Note: This was my original hypothesis paper (thought process). I started this journey with my own realization of my own autism. I knew that my own brain wasn’t broken and seemed to be working in overdrive and I asked the question: What if these brains already had a unique way of processing information and that was amplified? What would the consequences be and how could it happen. Since that time epigenetics (stress mechanisms, or gene-environment interaction) became mainstream and some of the percentages of the population have shifted. I have a very busy brain, so grabbing quotes (or speaking in script) is often how I communicate, as writing (communication of my multilayered and multidirection thinking) has always been my biggest struggle. I know this isn’t how typical papers are written, nor the correct way… but it was a way that worked for me.
Autism, Stress and The Creative Brain
The evidence collected in this theory suggest that the minds of a subpopulation within the Autism Spectrum inherently process information differently than the norm, or those within the average or majority population. These subgroups of individuals may have evolved or adapted neurophysiologically atypical in order to receive more or uniquely process information from their sensory systems.
“This means creative individuals remain in contact with the extra information constantly streaming in from the environment” says Peterson…”The normal person classifies an object, and then forgets about it, even though that object is much more complex and interesting than he or she thinks. The creative person, by contrast, is always open to new possibilities.” (Peterson 2000)
Just like certain individuals are born athletically unique, typically with more or less fast or slow twitch muscle fibers, it could be similar in the brain. Most, or the average population (60-80%) would have a general combination of brain processing potentials, but the creative individual (15-20%) would have more specific processing potentials for a unique sensory experience of the world (Casanova 2008, Courchesne 2005), usually receiving more information to process or processing the information from the senses in an atypical fashion (sometimes called lateral thinking).
“They’re not random (genes for Autism & Schizophrenia),” says Thomas Insel, Director of the National Institute on Mental Health. “They tend to cluster around genes that are important for brain development.”
MORE INFORMATION, UNIQUE THOUGHT PROCESSING MAY REQUIRE MORE NUTRIENTS RELATED TO NEURAL GROWTH
Throughout our history, we have always had communities and villages with a core (majority) group of stabilizing, social, community-oriented individuals, and we have always the periphery minds; the innovators, the scientists, the geeks, the artists and the creative.
Leo Kanner published his first paper identifying autistic children in 1943. Kanner didn’t know why the children, all born in the 1930s, acted that way, but noticed the parents were college-educated and career-oriented: lawyers, psychiatrists, scientists. He wrote, “In the whole group, there are very few really warmhearted fathers and mothers. For the most part, the parents, grandparents, and collaterals are persons strongly preoccupied with abstractions of a scientific, literary, or artistic nature, and limited genuine interest in people.”
“People divide roughly, it seems to me, into two kinds, or rather a continuum is stretched between two extremes. There are people people and things people.” —W. D. Hamilton, recognised as one of the most significant evolutionary theorists of the 20th century (2005, p. 205)
From his book “Avoid Boring People” James Watson states:
“It may be that (Mr. X) is not entirely to blame for his social ineptitude. His repeated failures to comprehend the emotional states of those he presided over might be indicative of the genetic hand he was dealt as a mathematical economist—the very cards that endowed him with great quantitative intelligence may also have disable the normal faculties for reading human faces and voices. The social incapacity of mathematicians is no mere stereotype; many of most brilliant are mild to full-blown cases of Asperger’s syndrome (the high-intelligence form of autism), perhaps the most genetically determined of known human behavioral “disabilities.” (Watson 2007)
In a simplistic understanding this population could be more susceptible because of additional information received by the sensory systems through abnormal, “not a reflection of the majority”, differences in the brain. And the extra energy and resource demand this puts on the body, its systems and organs. This sensitivity is also reflected in allergies, sensory dysfunction and emotional dysregulation. This is inclusive of over 50 disorders, most prominently are Autism spectrum, Personality Disorders, Alzheimer’s, Bipolar, and Schizophrenia and all of the organ dysfunctions that are typical in this group including Thyroid Dysfunction, Asthma, Kidney infections, GI dysfunctions, Immune dysfunction.
Neuroatypical, more readily affected by Neurotoxins, creating predictable patterns of Neurological and Neuropsychiatric Dysfunction
Spectrum disorders as Deterministic Chaos Patterns
1. An Initial Condition
2. Multiple and varied influences
3. A predictable pattern of outcomes
An initial condition: Lowered Latent Inhibition or unique brain mechanisms for sensory and information processing. Biochemical, neurophysiological, genetic and adaptive uniqueness of an internally varied group of individuals (approximately 20% of population); increased nutritional needs (precursor resources) and sensitivity in relation to the increased dendritic growth and information processing required.
Small but significant environmental influences: Lack of proper nutritional resources, exposures to toxins that affect mineral balances (heavy metals), fat-balances, neuro-inhibitors, neurotoxins, inflammation and endocrine influencers (chemicals/pesticides/hormones) on a more susceptible population; Negative social imprinting, primal need of acceptance unfulfilled, average personality (instead of individual health) being assumed the ideal. Sensory timelines ignored, the need for additional input neglected/or blocked for foundational learning.
Predictable Outcomes: The co-morbity and spectrum disorders of emotional, behavioral, developmental, personality, neurological and sensory dysfunction as a result from individuals with the capacity to perceive more or uniquely process incoming stimuli from environment; Autism, ADHD, Personality Disorders (BPD), Bipolar, Alzheimer’s, Schizophrenia and ensuing physical complaints, from pain disorders, endocrine/organ issues to bowel and sensory dysfunctions.
Oscillation or Periodic Cycles (required in Chaotic Systems): As demonstrated by Circadian and Ultradian rhythms suggesting a rebuilding or oscillating pattern for restorative neurochemical/energy needs of the brain/body.
Science might be giving us all the clues we need to solve this puzzle but science (old rules of science) could be preventing us from seeing it….
Stuck in the wrong box: Conventional medicine has typically seen diseases as having a single organic cause, and each disease was a separate individual entity. Diseases were from a dysfunction or mutation, something inherently wrong. Modern science has proven this to be an incorrect analogy.
With a new framework for delineating these disorders, it could be hypothesized that children develop the more distressing symptoms of Autism FROM ANY STRESSOR in the environment (as well as many other neurological and behavioral disorders, depending on the individuals’ initial “starting point” and the combination and timing of environmental factors involved). This stress would impede the ability to build neural pathways and the brain would then attempt to protect itself from excessive stimulation, more than what it can handle at the time, due to lack of and combination of resources needed. What the evidence seems to be suggesting is that our genetic or neurophysiological make-up, our responses to and our influences coming from the environment, the increases in our exposures to toxins that affect mineral balances (heavy metals), neurotoxins, inflammation (autoimmunity) and endocrine influencers (pesticides/hormones) could be creating a greater stress on the systems within a particular population. And quite possibly these populations, in evolutionary terms, could be ones that filter less of their sensory information, allowing them to be what some consider more “creative”, but the trade-off could be an increased susceptibility to dysfunction when the environment is not conducive to neural growth.
Children having a genetic predisposition could make them more prone to environmental damage. A neuro-atypical individual, plus neurotoxic exposure could create neurophysiological dysfunction.
PUTTING THE EVIDENCE TOGETHER
It might not be the lack of evidence; it might be a lack of framework to make sense of the evidence.

Creativity and Mental Illness
Creativity could be seen as a unique capacity of an individual to receive more sensory information than the normal from their environment. While Mental disorders are often associated with an overabundance of sensory information.

Typically developing control children showed no such discrepancy, and a similar contrast was observed when a sample of autistic adults was compared with a sample of nonautistic adults. We conclude that intelligence has been underestimated in autistics.

Nevertheless, this relationship is not equivalent to the claim that creative individuals necessarily suffer from psychopathology. A theoretical interpretation is offered in terms of the cluster of cognitive abilities and dispositional traits required for creative behavior and the impact of genetic and environmental factors in the emergence of this cluster.

Heaton P, Wallace GL (2004) Annotation: the savant syndrome. Journal of Child Psychology and Psychiatry 2004 45:899-911. Results: It has long been observed that savant skills are more prevalent in individuals with autism than in those with other disorders. Therefore, in this annotation we seek to explore the parameters of the savant syndrome by considering these skills within the context of neuropsychological accounts of autism. A striking finding amongst those with savant skills, but without the diagnosis of autism, is the presence of cognitive features and behavioural traits associated with the disorder. Conclusions: We thus conclude that autism (or autistic traits) and savant skills are inextricably linked and we should therefore look to autism in our quest to solve the puzzle of the savant syndrome.

People with autism-related disorders are less likely to make irrational decisions, and are less influenced by gut instincts, according to research funded by the Wellcome Trust. The study adds to the growing body of research implicating altered emotional processing in autism. Decision-making is a complex process, involving both intuition and analysis: analysis involves computation and more “rational” thought, but is slower; intuition, by contrast, is much faster, but less accurate, relying on heuristics, or “gut instincts”.
Bad Boys Really do get More Girls. From issue 2661 of New Scientist magazine, 18 June 2008, page 12 http://www.newscientist.com/article/mg19826614.100 The traits are the self-obsession of narcissism; the impulsive, thrill-seeking and callous behaviour of psychopaths; and the deceitful and exploitative nature of Machiavellianism. At their extreme, these traits would be highly detrimental for life in traditional human societies. People with these personalities risk being shunned by others and shut out of relationships, leaving them without a mate, hungry and vulnerable to predators. But being just slightly evil could have an upside: a prolific sex life, says Peter Jonason at New Mexico State University in Las Cruces. “We have some evidence that the three traits are really the same thing and may represent a successful evolutionary strategy.”

Besides, nerds can learn social skills if they approach them with the same intellectual rigor they bring to calculus, says Lawrence Welkowitz, a psychologist at Keene State College. He’s found that nerds can often master the subtleties of social interaction, compensating for disinclination with focus and practice. He runs a peer-mentoring program in which popular kids take nerds under their wing and give them tips on how to be cool. The exposure to the popular kids’ world gives nerds a taste of social acceptance, which inspires them to keep working at it. But the socialization process isn’t easy: At first, nerds tend to get more depressed as they get more social. “They realize it’s hard, and they’ve been missing out on a lot,” he says. “But eventually, they get more skilled.”

Neurotransmitters & Hormones related to Personality & Dysfunctions
Normal Dopamine: (From NewScientist Feb. 2009: How to control a Herd by David Robson):
Interest in the idea of a herd mentality has been renewed by work into mirror neurons – cells that fire when we perform an action or watch someone perform a similar action. It suggests that our brains are geared to mimic our peers. “We are set up for ‘auto-copy’,” says Haidt.
Neurological evidence seems to back this idea. Vasily Klucharev, at the Donders Centre for Cognitive Neuroimaging in Nijmegen, the Netherlands, found that the brain releases more of the reward chemical dopamine when we fall in line with the group consensus (Neuron, vol 61, p 140). His team asked 24 women to rate more than 200 women for attractiveness. If a participant discovered their ratings did not tally with that of the others, they tended to readjust their scores. When a woman realized her differing opinion, fMRI scans revealed that her brain generated what the team dubbed an “error signal”. This has a conditioning effect, says Klucharev: it’s how we learn to follow the crowd.
(Those with altered dopamine receptors…could be those who don’t follow the crowd, or at least are not chemically conditioned or rewarded to do so….they are novelty, sensory, new experience seekers or depend more on rational thought than on peer pressure)
Abnormal Dopamine: (from Helen Fisher PhD, Chemistry.com)
Explorers have a very active dopamine system, a brain chemical associated with the tendency to seek novelty, among other qualities. …Explorers have more energy than most people; they tend to be restless, sometimes fast-paced. And they are highly curious—”For always roaming with a hungry heart,” as Tennyson put it. Constantly generating new ideas or creative insights, they easily shift their attention from one thing to another.
“Our research suggests that in high novelty-seeking individuals,
the brain is less able to regulate dopamine.“
Dr David Zald

Why We Take Risks — It’s the Dopamine By Alice Park. Tuesday, Dec. 30, 2008
Earlier studies in rats had shown that animals that tend to explore and take more risks in new environments also tend to have fewer of these inhibitory receptors (for Dopamine), and Zald wanted to find out if the same was true in people. “This is one of those situations where the data came out essentially perfectly,” he says. “The results were exactly as we predicted they would be, based on the animal data.” That is, like the rats, humans who were more spontaneous and eager to take risks had fewer dopamine-regulating receptors than those who were more cautious.

DeYoung CG, Peterson JB, Higgins DM. Higher-order factors of the Big Five predict conformity: Are there neuroses of health? (2002) Personality and Individual Differences, 33 (4), pp. 533-552. We present a biologically predicated model of these two personality factors, relating them to serotonergic and dopaminergic function, and we label them Stability (Emotional Stability, Agreeableness, and Conscientiousness) and Plasticity (Extraversion and Openness). Based on this model, we hypothesize that Stability will positively predict conformity (as indicated by socially desirable responding) and that Plasticity will negatively predict conformity. A structural equation model indicates that conformity is indeed positively related to Stability (university sample: β=0.98; community sample: β=0.69; P<0.01 for both) and negatively related to Plasticity (university sample: β=−0.48, P<0.07; community sample: β=−0.42, P<0.05). These findings suggest that there are pros and cons of conformity, such that the most thorough conformists will tend to be stable but also rigid, less able to adjust to novelty or change.

Some researchers believe that dopamine dysfunction may be also involved in the development of borderline personality disorder (BPD) because of evidence that dopamine is involved in cognitive and emotional processing and the regulation of impulsive behaviors (which are related to BPD symptoms). In addition, antipsychotic medications that target dopamine receptors in the brain seem to reduce BPD symptoms
SCHIZOPHRENIA: Gupta M, Chauhan C, Bhatnagar P, et al. Genetic susceptibility to schizophrenia: role of dopaminergic pathway gene polymorphisms. Pharmacogenomics. 2009 Feb;10(2):277-91.
The dopamine (DA) hypothesis is the oldest and most established of the schizophrenia hypotheses. It has evolved from clinical observations, and received empirical validation from antipsychotic treatment and more direct testing from imaging studies. Although clearly not sufficient to explain the complexity of this disorder, it offers a direct relationship to symptoms and to their treatment.
High levels of the neurotransmitter dopamine (or its agonists) in the brain are thought to lower latent inhibition (Swerdlow 2003). Certain dysfunctions of the neurotransmitter glutamate have also been implicated, and the glutamate hypothesis of schizophrenia is increasingly being seen as an alternative to the dopamine hypothesis of schizophrenia.

Dr Brosnan said that men having levels of testosterone very much higher than normal for males would also create the right hemisphere dominated brain which could help in science. The extremes of low testosterone and high testosterone for men would create the scientific brain, and the normal range in the middle would create the ‘social science’ brain.
“This right brain development is at the expense of language abilities and people skills that men with a more usual level of testosterone develop and which can help them in social science subjects like psychology or education.”

The researchers then looked at boys’ and girls’ test performances separately and compared them to finger-length ratio measurements. They found a clear link between high prenatal testosterone exposure, indicated by the longer ring finger compared to the index finger, and higher scores on the math SAT.
Similarly, they found higher literacy SAT scores for the girls among those who had lower prenatal testosterone exposure, as indicated by a shorter ring finger compared with the index finger.
The researchers also compared the finger-lengths ratios to all the children’s SAT scores and found that a relatively longer ring finger—indicating greater prenatal exposure to testosterone—meant a wider gap in scores for math versus literacy (writing and critical reading).
“Finger ratio provides us with an interesting insight into our innate abilities in key cognitive areas,” Brosnan said, in a prepared statement.

“The shower curtain of inhibition was a term introduced by a Hungarian neuroanatomist by the name of Szentagothai. Otherwise it was also called a strong vertical flow of inhibition by Vernon Mountcastle. Having a lot of wires together without insulating them from adjacent modules may promote what is called ephaptic conduction, amplification, and therefore seizures.” ~Dr. Manuel Casanova
We know that epilepsy involves temporary bursts of excessive electrical activity in different locations in the brain, locations which house our bodily sensations and functions as well as our memories and emotions. Psychiatrist Dr. David Bear states that the abnormal brain activity found in temporal lobe epilepsy can play a role in creative thinking and the making of art by uniting sensitivity, insight and sustained, critical attention. According to Dr. Bear:
“A temporal lobe focus in the superior individual may spark an extraordinary search for that entity we alternately call truth or beauty.”
What is also clear in the discussion of genius and epilepsy is that some of the most famous people in history had seizures. People with epilepsy have excelled in every area.

The anticonvulsants are a diverse group of pharmaceuticals used in the treatment of epileptic seizures. Anticonvulsants are also increasingly being used the treatment of bipolar disorder, since many seem to act as mood stabilizers. The goal of an anticonvulsant is to suppress the rapid and excessive firing of neurons that start a seizure. Failing this, a good anticonvulsant would prevent the spread of the seizure within the brain and offer protection against possible excitotoxic effects that may result in brain damage. However, anticonvulsants themselves have been linked to lowered IQ in children. (from Wikipedia 1/2009)
(reduce GABA, reduce dendritic growth and neuronal firing in the brain, these brains have more information than normal-they need more resources, when the resources are blocked/neglected…the stimulation grows unchecked and un-insulated…the anticonvulsants could theoretically stops them from having too much information…more information is a higher IQ, stop the communication, you stop seizures, but could we just stop the inflammation and toxicity and any other issues that would create the seizures?)

CHARACTER TYPES by Dr. Michael Lesser
What is wholly unique about Dr. Lesser theory is that he believes ALL individuals have these in-balance and out-of-balance personas. That the mental illnesses we see are reflections of a particular personality simply gone awry, out-of-balance, or maladaptive.
Dr. Lesser determined his character typing using first the “Five Factor Model (FFM)”of personality and then the biochemical markers of histamine, cortisol, serotonin and copper/zinc/magnesium; he noticed there were certain patterns within each “character-type”.
Dr. Lesser, suggests that the “Stoic” personality is the most common of all character types, estimating over 50% of his patients’ exhibit these traits. Why would this be significant? Because over 50% makes the Stoic Personality “normal” or the “average” personality. And if there is a majority personality and our current medical model assumes a static state initial condition, when there are actually variable initial conditions corresponding to unique physiological and neurophysiological aspects that reflect personality….then we have been making many incorrect assumptions about timelines, expectations and the measurement of “ideal”….

Interview from TIME magazine:
You basically break people down into four broad temperaments, each associated with certain brain chemicals.
There was a great deal of data that people vary in terms of their expression of dopamine and norepinephrine, serotonin, estrogen and oxytocin and testosterone. I culled from the academic literature all of those data points that show that these particular brain-chemical systems are related to certain aspects of personality. And I saw constellations of temperament traits that seemed to be associated with these chemicals.
What are the four types?
People who express dopamine — I call them Explorers — tend to be risk-taking, curious, creative, impulsive, optimistic and energetic. The traits associated with the serotonin system express themselves in what I call Builders. They’re cautious but not fearful, calm, traditional, community-oriented, persistent and loyal. Directors have traits associated with activity in the testosterone system. These people tend to be very analytical, decisive, tough-minded; they like to debate and can be aggressive. The fourth type is the Negotiator. Men or women who express activity in the estrogen system tend to be broadminded imaginative, compassionate, intuitive, verbal, nurturing, altruistic and idealistic.
How did you choose the four types and ascertain who they like?
They emerged out of the genetic literature. I didn’t impose them. I read the literature, and I found them. And then I developed the questionnaire to make sure these people did express these four [types of temperament] and expressed them in these ways. That study was done on 40,000 people. And then on the dating site Chemistry.com.

An Evolutionary Advantage
Why might a socially balanced, effective filtering Personality be more common?
From an evolutionary standpoint they represent stability, community & socializing personalities. Linear thinking, salt of the earth, socially-oriented, core characteristics for a stable community.
And the more creative, less socially inclined, less filtering Peripheral Minds?
Might represent the possibilities of human experience, passion, innovation, change-makers, reality-truth seekers. The periphery of human existence, the forces of change, exuberance, understanding and the seekers of knowledge and fundamental understanding.
STABILITY. COMMUNITY. COHESION. AN AGREED UPON REALITY.
CREATIVITY. INNOVATION. DISCOVERY. CHANGE. TRUTH.
There could easily be an evolutionary advantage to stability plus possibility in social structures and communities.
The mistakes of the measuring stick
(Everyone is unique in their own way…but there are patterns of similarities)
We all have different potentials and different inborn skills. We are all equal and needed and special and important to our community, our families, and the advancement of the human race. And there could be an evolutionary benefit to having a minority with variable neurophysiological experiences of the world…
How did this happen?
The Bell Curve gone wrong: Measure the average.
Unfortunately the Average Acumen might fall to the average personality. Or the Stoic. So all standards, testing, developmental expectations would be for the traits of the average Stoic who has very effective filtering systems and social-based skills. So they develop and learn very differently than less-filtering character types: the Star, the the Lover and the Dreamer. These character types need more information to learn the same concepts, because they learn them fundamentally and with more information.
Their learning curve appears to be different. They may need more information, more possibilities, more challenges, and different angles to fully identify with the concept at hand (including sensory information). Or learn different skills at different times in their development (See “Brain Matures a Few Years Later but at normal Pace for ADHD” Shaw 2007).These differences will seem un-normal, slow or scattered, but they must build the same foundations as all children must.
Genius: someone who sees reality differently or more clearly than others; one who receives or comprehends more information from their environment than the norm.
Madness: someone who sees reality differently or more clouded than others; one who receives but cannot comprehend the excessive information coming in from their environment.
Further prominent examples of genius and madness: Einstein’s son, Eduardo and James Watson’s son with schizophrenia. John Nash. …. Many great scientists in our past or present could be associated with either a personality disorder or within the Autistic-Asperger’s spectrum. Asperger’s is also known as the “Geek-Syndrome”…
This is the fine line. And there could be any number of stressors that could cause the circuitry in the brain to not fully process information and lead to sensory dysfunction. It is possible that this “excess” of information could lead an individual to require learning information differently than the norm, sometimes more quickly and sometimes it could take much longer, either because of distractions (or longer ways around), or because they learn things much more intimately and fundamentally than their peers and this takes more precise information and sometimes more information than what is offered or available at that time (but the thought still got started, the dendrites were put into action and want to finish their circuitry). And ultimately this increased information, with its subsequent dendrites, neural responses, and neurotransmitters are not produced in a vacuum, they are not just available in a static manner, they need to be manufactured and regulated by a multitude of organs, systems, raw material and energy, we could make an assumption from the evidence that if any of these pathways are inhibited in any way the information would not be processed properly or the pathways would have difficulty being built…and these necessary components would naturally and under normal conditions work differently than those who filter their environments more efficiently (don’t receive as much information) and these individuals, who have more information to process (creative), would require more nutritional or raw materials from their systems and their outside environment than the average, a person receiving less sensory input.
Genes, Inherited traits, Expression, Patterns and Clues
A genetic disease is very different than an inheritable genetic susceptibility, especially when we know that we can no longer look for that “magic bullet” answer from genetic research…
Scientists have spent years looking for a “schizophrenia gene” and an “autism gene,” but the search has been frustrating. They have ID’d genes that make people susceptible to the disorders, but none of those genes are shared by enough people … “They’re not random,” says Thomas Insel, director of the NIMH “They tend to cluster around genes that are important for brain development.” (Shute 2008)

There is broad agreement that genetic influences are central in the development of idiopathic autism. Whether relatives manifest genetically related milder phenotypes, and if so how these relate to autism proper, has proved a more contentious issue. A review of the relevant studies indicates that relatives aresometimes affected by difficulties that appear conceptually related to autistic behaviors. These range in severity from pervasive developmental disorders to abnormalities in only one area of functioning, and possibly extend to related personality traits. Issues involved in clarifying the components of milder phenotypes and their relationship to autism are outlined

Filtering Systems: Receptors in the Brain
Excitatory and Inhibitory Pathways for Information Management
GABA and GLUTAMATE
GLUTAMATE: A genome scan was previously performed and pointed to chromosome 6q21 as a candidate region for autism. This region contains the glutamate receptor 6 (GluR6 or GRIK2) gene, a functional candidate for the syndrome. Glutamate is the principal excitatory neurotransmitter in the brain and is directly involved in cognitive functions such as memory and learning. (Jamain, 2008). Among the new clues is stronger evidence for an association between autism and sites of genes for neurexins, molecules that build glutamate synapses; the connection machinery by which brain cells communicate.
GABA: Since one of the primary functions of GABA is to inhibit nerve cells from firing, it plays a key role in telling the body to “slow down.” The GABA system therefore acts as a sort of information filter, preventing the brain from becoming over-stimulated, the researchers explained. “Impairing the GABA system could overwhelm the brain with sensory information, leading to both the behavior and the pattern of cell damage that emerges in autism,” said John Hussman, Ph.D., a study co-author and president of The Hussman Foundation, one of the groups that funded the study. The researchers examined 14 genes that encode portions of the GABA receptor in 470 Caucasian families. Of those families, 266 included more than one person with autism and 204 included one autistic individual. The team tested for associations between particular gene variants and the disease. They also applied sophisticated statistical methods designed to zero in on the effects of particular gene combinations. The researchers found that one of the GABA receptor genes, GABRA4, is involved in the origin of autism. Moreover, they report, GABRA4 appears to increase autism risk through its interaction with a second GABA gene, GABRB1. (Pericak-Vance, M. American Journal of Human Genetics, September 2005; vol 77)
Frith CD, Frith U. The self and its reputation in autism. Neuron. 2008 Feb 7;57(3):331-2. The findings reveal an unusual lack of brain activity in mid cingulate cortex when they make their investments.

According to estimates, approximately one in every hundred persons experiences a schizophrenic episode at least once in their lives.. in addition to environmental factors, genetic components are crucial—approximately 80 percent according to estimations.

Momoi T, Fujita E, Senoo H, Momoi M. Genetic factors and epigenetic factors for autism: endoplasmic reticulum stress and impaired synaptic function. Cell Biol Int.;34(1):13-9.
The molecular pathogenesis of ASD (autism spectrum disorder), one of the heritable neurodevelopmental disorders, is not well understood, although over 15 autistic-susceptible gene loci have been extensively studied. A major issue is whether the proteins that these candidate genes encode are involved in general function and signal transduction. Several mutations in genes encoding synaptic adhesion molecules such as neuroligin, neurexin, CNTNAP (contactin-associated protein) and CADM1 (cell-adhesion molecule 1) found in ASD suggest that impaired synaptic function is the underlying pathogenesis. However, knockout mouse models of these mutations do not show all of the autism-related symptoms, suggesting that gain-of-function in addition to loss-of-function arising from these mutations may be associated with ASD pathogenesis. Another finding is that family members with a given mutation frequently do not manifest autistic symptoms, which possibly may be because of gender effects, dominance theory and environmental factors, including hormones and stress. Thus epigenetic factors complicate our understanding of the relationship between these mutated genes and ASD pathogenesis. We focus in the present review on findings that ER (endoplasmic reticulum) stress arising from these mutations causes a trafficking disorder of synaptic receptors, such as GABA (gamma-aminobutyric acid) B-receptors, and leads to their impaired synaptic function and signal transduction. In the present review we propose a hypothesis that ASD pathogenesis is linked not only to loss-of-function but also to gain-of-function, with an ER stress response to unfolded proteins under the influence of epigenetic factors.
Moalem S, Percy ME. (2004). The quandary of reductionism: relevance to Alzheimer disease research. Journal of Alzheimers Disease, 4(6): 531-7
Modern science has embraced reductionism, seeking ever-smaller parts to explain the whole. Although reductionistic approaches are successful in very simple biological modeling, they are not necessarily appropriate for systems of increasing complexity. Drawing on famous historical examples of how non-reductionist thinking has benefited mankind, and of how reductionism has sometimes led to erroneous conclusions, we call attention to the need to move away from purely linear reasoning in order to succeed in addressing many of the problems we face with the predicted demographic increase in seniors, and the increase in numbers of those afflicted with Alzheimer disease. The time has come to reconsider and seriously question our most basic assumptions and beliefs surrounding what we believe Alzheimer disease to be, without which we run the risk of missed opportunities and failure.

“It is clear that intelligence is at least partly genetically determined. This was supported by the discovery in 2001 that the volume of the brain’s grey matter, made up of “processor” cells, is heritable and correlates with certain elements of IQ (Nature Neuroscience, DOI: 10.1038/nn758). The amount of white matter, which provides the connections between these processors, has since been shown to be heritable too (Journal of Neuroscience, vol 26, p 10235). Now it seems that the quality of these connections, which is governed by the integrity of the protective myelin sheath that encases them, is also largely genetic, and correlates with IQ

The establishment of appropriate neural circuitry depends on the coordination of multiple developmental events across space and time. These events include proliferation, migration, differentiation, and survival-all of which can be mediated by hepatocyte growth factor (HGF) signaling through the Met receptor tyrosine kinase. We previously found a functional promoter variant of the MET gene to be associated with autism spectrum disorder, suggesting that forebrain circuits governing social and emotional function may be especially vulnerable to developmental disruptions in HGF/Met signaling. …Temporally, peak expression of transcript and protein occurs during the second postnatal week. This period is characterized by extensive neurite outgrowth and synaptogenesis, supporting a role for the receptor in these processes. Collectively, these data suggest that Met signaling may be necessary for the appropriate wiring of forebrain circuits, with particular relevance to the social and emotional dimensions of behavior.

Objective: Catechol-O-methyltransferase (COMT) gene was hypothesized to have a relationship with human prefrontal cortex (PFC) function and individual cognitive abilities. The object of this study was to investigate the possible impact of genotypes of COMT Val158Met polymorphism on cognitive ability among children living in the Qinba region in China. Conclusion: Our results indicate that COMT gene Val158Met polymorphism may be related to the intelligence of Chinese girls, although the results cannot withstand multiple testing. Consequently, further studies with larger samples and perfect design still need place more emphasis on the gender difference and compensation effect of dopamine activity in PFC.

SENSORY INTER-RELATIONSHIPS AND LEARNING
(Information comes in from ALL the sensory organs, but filter through common pathways of the cerebellum)
It could be hypothesized that the varied progressive symptoms/dysfunctions of these disorders stem from aspects of sensory processing: Too much information and/or not enough resources to process information.
The success of mainstream treatments (like ABA/OT), which give the children additional, focused, repetitive information, may be a clue that these minds did not or cannot process or receive this information for neurophysiological programming. These therapies may work by completing the pathways for learned behavior/knowledge which had been previously or continues to be clouded by excessive “noise” (similar to information bottlenecks) or the lack of resources and raw materials needed to build these pathways from the incoming sensory information (myelination).
Could these therapies at times be similar to pulling a truck through the mud? Yes, you can get results (the truck moves), but might it be easier if we first got rid of the mud?
Critical learning periods during childhood, the peripheral mind and the lack of resources complicated by too much information could create information “bottlenecks”; either not learning when they need to, the information is not able to get through (or myelinated appropriately, see Bartzokis 2004) or not having enough information for complete processing.
THOUGHT: (Sensory information is also learned and myelinated) And retraining seemingly unrelated aspects of the senses, such as Behavioral Optometry, Cerebellar “exercises” that re-stimulate or retrain vision, hearing or balance, will reportedly make vast improvements in behavior, emotions, memory and in some cases increase IQ (IQ may also be related GABA, hence the lowered IQ with GABA-inhibiting drugs of anti-epileptics). (thought: could this type of retraining be either finishing or rewiring or improving the brain’s sensory “learning” to work more efficiently and this eliminates confusing or unfinished “business” as a drain on resources, less confusing, less bottlenecks, more info can get through, get myelinated, get recalled, get neurotransmitted.)

Figure from Ashwin et al. 2008 (Biological Psychiatry)
(Crespi cont.) Might this be an isolated finding, a quirk of neurodevelopmental nature? Previous work has revealed enhanced auditory pitch discrimination in autism (Bonnel et al. 2003; O’Riordan and Passetti 2006), as well as increased sensitivity to vibration and thermal pain (Cascio et al. 2008), increased tactile sensitivity (Blakemore et al. 2006), olfactory sensitivities comparable to those of canines (Bogdashina 2003, p. 54), superior abilities in visual search tasks (O’Riordan et al. 2001), generally enhanced perception of relatively simple, static stimuli (Mottron et al. 2006), and evidence for ‘enhanced functioning and role of the primary visual cortex’ (Caron et al. 2006). More generally, autistics have recently been shown to exhibit higher ‘fluid intelligence’ – a form of problem-solving intelligence independent of acquired knowledge, higher than that of non-autistic controls (Dawson et al. 2007; Hayashi et al. 2008), also lending support to the idea that the previously-perceived association of autism with mental retardation is due to biases in ascertainment and diagnosis (Skuse 2007).
The implications of these findings for our understanding of the autistic and so-called normal brains, the evolutionary bases of autism, and societal perception of autistics, are difficult to overstate. The simplest, albeit preliminary, neurological explanation for perceptual and analytic enhancements in autistics is that their brains are ‘tuned’ to higher frequencies (Blakemore et al. 2006) due to differences in neuronal micro-architecture (Casanova et al. 2003) and greater emphasis on left-hemispheric, local-processing, high-frequency abilities (Ivry and Robertson 1998; Cook 2002; Han et al. 2002; Wang et al. 2007). At an evolutionary level, Grandin and Johnson (2005) have likened autistic savant talents to the enhanced sensory and memory skills of animals, and strong signals of positive Darwinian selection along the human lineage have consistently been reported for genes underlying sensory perception (e. g., Nielsen et al. 2005).
Whatever the proximate and ultimate explanations for eagle-eyed autism, Ashwin et al. (2008) have opened new doors to our understanding of perception, and the many meanings of what it means to be human and autistic.

…Note from the text of the full paper that stress causes the release of the hormone corticosterone which lowers latent inhibition. In a nutshell, when an organism runs into problems that cause stress the resulting release of stress hormones causes the mind to shift into a state where it will examine factors in the environment that it normally ignores. This allows the organism to look for solutions to the stress-causing problem that would be ignored in normal and less stressed circumstances.
From Future Pundit:
So perhaps we could hypothesize something like this under stressful conditions, or in personality conjurations characterized by increased novelty-sensitivity, approach behavior, and DA activity, decreased LI is associated with increased permeability and flexibility of functional cognitive and perceptual category [see Barsalou (1983)for a discussion of such categories ].Imagine a situation where current plans are not producing desired outcomes —a situation where current categories of perception and cognition are in error, from the pragmatic perspective. Something anomalous or novel emerges as a consequence (Peterson, 1999), and drives exploratory behavior. Stress or trait-dependent decreased LI, under such circumstances, could produce increased signal (as well as noise), with regards to the erroneous pattern of behavior and the anomaly that it produced. This might offer the organism, currently enmeshed in the consequences of mistaken presuppositions, the possibility of gathering new information, where nothing but categorical certainty once existed. Decreased LI might therefore be regarded as advantageous, in that it allows for the perception of more unlikely, radical and numerous options for reconsideration, but disadvantageous in that the stressed or approach-oriented person risks ‘‘drowning in possibility,’’ to use Kierkegaard ’s phrase.

The modular arrangement of the neocortex is based on the cell minicolumn: a self-contained ecosystem of neurons and their afferent, efferent, and interneuronal connections. The authors’ preliminary studies indicate that minicolumns in the brains of autistic patients are narrower, with an altered internal organization. More specifically, their minicolumns reveal less peripheral neuropil space and increased spacing among their constituent cells. The peripheral neuropil space of the minicolumn is the conduit, among other things, for inhibitory local circuit projections. A defect in these GABAergic fibers may correlate with the increased prevalence of seizures among autistic patients. This article expands on our initial findings by arguing for the specificity of GABAergic inhibition in the neocortex as being focused around its mini- and macrocolumnar organization. The authors conclude that GABAergic interneurons are vital to proper minicolumnar differentiation and signal processing (e.g., filtering capacity of the neocortex), thus providing a putative correlate to autistic symptomatology.
Brain Anatomical Network and Intelligence
PLoS Comput Biol, Vol. 5, No. 5. (29 May 2009), e1000395.
Author Summary: Networks of interconnected brain regions coordinate brain activities. Information is processed in the grey matter (cortex and subcortical structures) and passed along the network via whitish, fatty-coated fiber bundles, the white matter. Using maps of these white matter tracks, we provided evidence that higher intelligence may result from more efficient information transfer. Specifically, we hypothesized that higher IQ derives from higher global efficiency of the brain anatomical network. Seventy-nine healthy young adults were divided into general and high IQ groups. We used diffusion tensor tractography, which maps brain white matter fibers, to construct anatomical brain networks for each subject and calculated the network properties using both binary and weighted networks. We consistently found that the high intelligence group’s brain network was significantly more efficient than was the general intelligence group’s. Moreover, IQ scores were significantly correlated with network properties, such as shorter path lengths and higher overall efficiency, indicating that the information transfer in the brain was more efficient. These converging evidences support the hypothesis that the efficiency of the organization of the brain structure may be an important biological basis for intelligence.

The present study investigated the performance of children with and without autism on auditory and tactile discrimination tasks and revealed superior auditory but comparable tactile discrimination in autism relative to controls. These results extend previous findings of perceptual discrimination in autism and may be relevant for a neuro-developmental hypothesis of the disorder.

DOI: 10.1126/science.272.5261.545. Recent evidence that the cerebellum is involved in perception and cognition challenges the prevailing view that its primary function is fine motor control. A new alternative hypothesis is that the lateral cerebellum is not activated by the control of movement per se, but is strongly engaged during the acquisition and discrimination of sensory information. Magnetic resonance imaging of the lateral cerebellar output (dentate) nucleus during passive and active sensory tasks confirmed this hypothesis. These findings suggest that the lateral cerebellum may be active during motor, perceptual, and cognitive performances specifically because of the requirement to process sensory data.

Recent neuroimaging data, including voxel based morphometry, PET and fMRI, revealed that the insular cortex was involved in various neuropsychiatric diseases such as mood disorders, panic disorders, PTSD, obsessive-compulsive disorders, eating disorders, and schizophrenia. Investigations of functions and connections of the insular cortex suggest that sensory information including gustatory, olfactory, visual, auditory, and tactile inputs converge on the insular cortex, and that these multimodal sensory information may be integrated there.
Rice, S. Barone, D.Jr. Critical periods of vulnerability for the developing nervous system: evidence from humans and animal models. Environ Health Perspect. 2000 June; 108(Suppl 3): 511–533. Vulnerable periods during the development of the nervous system are sensitive to environmental insults because they are dependent on the temporal and regional emergence of critical developmental processes (i.e., proliferation, migration, differentiation, synaptogenesis, myelination, and apoptosis) …Furthermore, various clinical disorders in humans (e.g., schizophrenia, dyslexia, epilepsy, and autism) may also be the result of interference with normal ontogeny of developmental processes in the nervous system. Of critical concern is the possibility that developmental exposure to neurotoxicants may result in an acceleration of age-related decline in function. This concern is compounded by the fact that developmental neurotoxicity that results in small effects can have a profound societal impact when amortized across the entire population and across the life span of humans

Additional neurobiological experiments-both on the pattern of sensory inputs to the cerebellum and on the ways in which the cerebellum processes that information-also suggest a need to substantially revise current thinking about the function of this organ

Thought: Interconnections of the sensory systems AND the unique qualities within this community suggest not only a need for unique resources, but a need for unique stimulation, and unique potential.
Physicist David Bohm (1982) asserts that the root cause of this crisis of perception lies in our habit of seeing and experiencing ourselves and our world as constituted of separately existent fragments. “The notion that all these fragments are separately existent is evidently an illusion, and this illusion cannot do other then lead to endless conflict and confusion.”
Unique starting points or processing potentials create unique but predictable outcomes from distinct environmental influences.
MENTAL ILLNESS IS NOT WHAT WE HAVE CLASSICALLY UNDERSTOOD IT TO BE. AS DIFFICULT AS IT MIGHT BE TO IMAGINE THAT THESE DISORDERS ARE RELATED NOT ONLY TO EACH OTHER AS DIAMETRICALLY OPPOSED OR MANIFESTED SLIGHTLY DIFFERENTLY DEPENDING ON TIMING, LEVEL OF ASSAULT, EXPERIENCE OR LACK OF RESOURCES, BUT THEY ALSO INVOLVE MULTIPLE ORGANS AND SYSTEMS THAT AGAIN RELATE BACK TO EACH OTHER. SO A CROSS-OVER OF EVIDENCE FROM MANY FIELDS MAY START GIVING US A BIGGER INTEGRATED PICTURE OF THE WHOLE.
“Could autism and schizophrenia be cousins? New research shows that people with schizophrenia have rare variations in genes that control brain development and that each person has a unique pattern of mutations. The finding is startlingly similar to new research on autism…. Thomas Insel, a psychiatrist who heads the National Institute of Mental Health, calls the new understanding that disorders like schizophrenia and autism have unique origins in each person a “Tolstoy moment”(Happy families are all alike; every unhappy family is unhappy in its own way) in mental health. ~ (Shute 2008).
… findings such as the frequency of comorbidity among the major diagnostic entities have led to systematic studies of their boundaries and renewed questions about categorical vs dimensional approaches to classification. (Insel 2008: Psychiatric Epidemiology)
Anckarsater, H, Stahlberg, O, et al. The Impact of ADHD and Autism Spectrum Disorders on Temperament, Character, and Personality Development. Am J Psychiatry, 2006 163: 1239-1244. RESULTS: Patients with ADHD reported high novelty seeking and high harm avoidance. Patients with autism spectrum disorders reported low novelty seeking, low reward dependence, and high harm avoidance. Character scores (self-directedness and cooperativeness) were extremely low among subjects with neuropsychiatric disorders, indicating a high overall prevalence of personality disorders, which was confirmed with the SCID-II. Cluster B personality disorders were more common in subjects with ADHD, while cluster A and C disorders were more common in those with autism spectrum disorders. The overlap between DSM-IV personality disorder categories was high, and they seem less clinically useful in this context. CONCLUSIONS: ADHD and autism spectrum disorders are associated with specific temperament configurations and an increased risk of personality disorders and deficits in character maturation.

Abstract: Autistic-spectrum conditions and psychotic-spectrum conditions (mainly schizophrenia, bipolar disorder, and major depression) represent two major suites of disorders of human cognition, affect, and behavior that involve altered development and function of the social brain. We describe evidence that a large set of phenotypic traits exhibit diametrically opposite phenotypes in autistic-spectrum versus psychotic-spectrum conditions, with a focus on schizophrenia. This suite of traits is inter-correlated, in that autism involves a general pattern of constrained overgrowth, whereas schizophrenia involves undergrowth. These disorders also exhibit diametric patterns for traits related to social brain development, including aspects of gaze, agency, social cognition, local versus global processing, language, and behavior. Social cognition is thus underdeveloped in autistic-spectrum conditions and hyper-developed on the psychotic spectrum. We propose and evaluate a novel hypothesis that may help to explain these diametric phenotypes: that the development of these two sets of conditions is mediated in part by alterations of genomic imprinting. Evidence regarding the genetic, physiological, neurological, and psychological underpinnings of psychotic-spectrum conditions supports the hypothesis that the etiologies of these conditions involve biases towards increased relative effects from imprinted genes with maternal expression, which engender a general pattern of undergrowth. By contrast, autistic-spectrum conditions appear to involve increased relative bias towards effects of paternally expressed genes, which mediate overgrowth. This hypothesis provides a simple yet comprehensive theory, grounded in evolutionary biology and genetics, for understanding the causes and phenotypes of autistic-spectrum and psychotic-spectrum conditions.

A basic structural abnormality in the frontal cortex might cause these individuals to have higher psychiatric comorbidity (not only of ASPD and SSPD) and the abnormal characteristics identified might not be entirely explained by the co-occurrence of these two disorders. The authors have rightly identified that the results could not merely be due to the additive effects of both disorders, but that the increased prevalence of personality disorder in the study population might be due to a common confounder that does not lie on the causal pathway between ASPD/SSPD and abnormality in characteristics.
Newcorn, J, Sprich, S. Comorbidity of attention deficit hyperactivity disorder with conduct, depressive, anxiety, and other disorders. Am J Psychiatry, 1991 148: 564-577 FINDINGS: The literature supports considerable comorbidity of attention deficit hyperactivity disorder with conduct disorder, oppositional defiant disorder, mood disorders, anxiety disorders, learning disabilities, and other disorders, such as mental retardation, Tourette’s syndrome, and borderline personality disorder. CONCLUSIONS: Subgroups of children with attention deficit hyperactivity disorder might be delineated on the basis of the disorder’s comorbidity with other disorders. These subgroups may have differing risk factors, clinical courses, and pharmacological responses. Thus, their proper identification may lead to refinements in preventive and treatment strategies. Investigation of these issues should help to clarify the etiology, course, and outcome of attention deficit hyperactivity disorder.

Whilst not always quantifiable, no patient was found to have one condition in isolation and comorbidity rates were found at incidences of up to 95%, representing an increase on the expected prevalence in a general population of 160-2300%.Conclusion The patterns of comorbidity occurred with such frequency that it would suggest that there could be an argument for the downgrading of these conditions from disorders per se to symptoms and that further investigation might suggest that the patterns of comorbidity may fit the criteria for a developmental delay syndrome.

Thought: When we begin to see these entities as connected patterns, we can begin to see the patterns of development and the research delineating what we once that were “separate” disorders can now be seen as interconnected…and the evidence begins making a more coherent picture of the whole. Just like climates, similarities and variability…and not distinguished entities.
BRAINGUT: Enteric Nervous System
Recently a study in ScienceDaily from Dr. Pat Levitt stated that the Met Gene was implicated in both Autism and Gut disorders. “Met Gene is expressed in the brain during development and is important for a number of different processes, including cell migration, development of excitatory and inhibitory neurons, synapse formation, and myelination”. (Levitt 2009) So if the “second brain” also needs these same pathways built during critical “learning” periods for sensory organs, such as digestive system and immune system (both have sensory aspects, both need to respond readily to environmental conditions and become programmed to respond), could this genetic relation to these processes be another affirmation that these individuals are not getting the necessary resources to build neurological pathways?
“The Second Brain”: The enteric nervous system also makes use of more than 30 neurotransmitters, most of which are identical to the ones found in CNS, such as acetylcholine, dopamine, and serotonin. The enteric nervous system has the capacity to alter its response depending on such factors as bulk and nutrient composition. In addition, ENS contains support cells which are similar to astroglia of the brain and a diffusion barrier around the capillaries surrounding ganglia which is similar to the blood-brain barrier of cerebral blood vessels.

But 95 percent of the body’s serotonin is housed in the gut, where it acts as a neurotransmitter and a signaling mechanism. Serotonin also acts as a go-between, keeping the brain in the skull up to date with what is happening in the brain below. Such communication is mostly one way, with 90 percent traveling from the gut to the head.”You can run any test you want on people with IBS, and their GI tracts look essentially normal,” Mawe said.

(Could PTSD have a direct relationship with the increased memory/emotional response to sensory experience in this “peripheral” population?)
The consistency around the 20% mark for the population is an extremely important clue. This mathematical representation is a uniqueness of experience in a minority, 20%, of the population. The research on PTSD, that after a traumatic event it is not a “random” number of individuals that develop this syndrome. It appears to affect those that are more susceptible…to memory, emotions, and experience of their surroundings. The same is true for those that express “emotional dysregulation” in the study of French students, not exactly a disorder, but what seems to be a precursor to “borderline personality”, borderline personality is characterized by emotional dysregulation, fear of abandonment (aka not fitting in/not being normal), they are also many times highly personable, flexible in thought and action, successful, creative, dynamic individuals…

And when learning every aspect of a particular problem is required in order to resolve a condition, it’s easy to understand that in some cases it never happens, so the foundation of said subject never gets laid and built upon, or the child/adult lives their lives unresolved and in constant conflict/crisis mode.
It could be hypothesized that the brain was set-up this way to finish thoughts started, to inspire or even demand for human to “figure things out” and all of these pathways serve a purpose, anger, frustration, obsession, compulsion, single-mindedness…starting a multitude of “branches”, more than the normal individual, gives their brains much more to do, more directions to follow, more information to take in…which could serve a purpose.
Nutrition & Resources
- Intense mental needs (equivalent to running mini-mental marathons on a daily basis) lead to intensely delicate balance of chemicals, requirements, recovery and restoration. Just as physical demands require additional provisions, so does mental demands, they actually require MORE energy and resources. The brain uses 20% of total calorie needs (75% during infancy) daily for “normal” functioning, the brain represent 2-3% of body weight, it also receives it’s energy from primarily glucose, unlike the body which can use either glucose or fat for energy. So living in the mind and especially when the mind is in overdrive, can be a drain on the systems, resources and organs of the body.
Social & Acceptance
- So what would happen to any child if they felt or knew they were fundamentally different and that being different would mean that they would not be understood or accepted, socially rejected or shunned? And the alternative, what would happen to any child if they spent their lives trying to fit in by being something they are not? Because this competition to be the best “normal” as possible, when that normal is defined by personality characteristics as opposed to value characteristics, causes emotional unrest in these individuals, when our values are on a personality preferences that they simply can never become. You cannot wish or train yourself into physiological personality characteristic & traits.
People evolve for a multitude of purposes, our bodies are created to adapt and change. If the “geeks/artists/scientists” of the world are lacking filters or have other chemical uniqueness that allows them to live with more possibilities, then the biochemically individuality of these individuals may also set them up to be more environmentally sensitive or have compensatory actions, such as emotional sensitivity (different than norm) as a way to balance the influx of information.
Nutrition and the Mind
Drugs show an effect. Drugs can demonstrate a particular mechanism of action. Drugs have linear, singular, straight-line observable, cause and effect action. Drugs work beautifully once something is broken or depleted. This shows a direct effect and it is this type of disease that is in the realm of Classical Physics. Classical Physics in medicine also assume a static starting point.
But research has shown that our physiological minds are in constant ebb and flow; a reflection and response to our environment. Evolutionary Biology is demonstrating this fact. And changing the nutritional components of food in order to “kill germs”, preserve and make food more economically viable, created a multitude of subtle changes in the availability, combination and interaction of nutrition of those foods and their inherent properties. And this in turn could reflect and impact the ability of our minds to process information (especially frontal lobes) and for the interactive systems of the body to function optimally.

Bartzokis G. Brain myelination in prevalent neuropsychiatric developmental disorders: primary and comorbid addiction. Adolesc Psychiatry. 2005;29:55-96.PMID: 18668184
The role of nutrition may be particularly important. In order to build membranes – “and myelin is the ultimate membrane” – the body requires sufficient supplies of essential fatty acids found in fish oils, flaxseed, grains and nuts. But the diets of young people are notoriously poor, he says, and likely to be deficient in key nutrients.
Dr. Bartzokis and his team described the younger brain undergoing myelination and what can happen if those connections don’t develop normally.
Dr. Bartzokis believes that humans brains myelinate different circuits at varying points throughout life, which may explain why the brain diseases of young people are frequently very different than those of older people.
An example is if myelin is disrupted early in life, basic circuits that govern language and social communication might not develop normally, hence autism.
If the problems develop in school-age children, the inability to process information fast and effectively might result in the development of attention deficits. Later in adolescence, problems with myelin can impair a person’s ability to think clearly, a common feature of schizophrenia. http://www.schizophrenia.com/sznews/archives/002685.html

CONCLUSIONS: Zinc monotherapy was significantly superior to placebo in reducing symptoms of hyperactivity, impulsivity and impaired socialization in patients with ADHD. Although by themselves, these findings may not be sufficient, it may well be considered that zinc treatment appears to be an efficacious treatment for ADHD patients having older age and high BMI score with low zinc and FFA levels.
Black M. Zinc deficiency and child development. Am J Clin Nutr 1998;68:464S– 9S [Suppl.]. Zinc is a trace metal that is present in the brain and contributes to its structure and function. Limited evidence from both animal and human studies suggests that zinc deficiency may lead to delays in cognitive development. Although the mechanisms linking zinc deficiency with cognitive development are unclear, it appears that zinc deficiency may lead to deficits in children’s neuropsychologic functioning, activity, or motor development, and thus interfere with cognitive performance.

Ebaldi M, Murrin LC, Pfeiffer RF. Hippocampal zinc thionein and pyridoxal phosphate modulated synaptic function. Vitamin B-6. Annals of the New York Acad of Sci 1980. p. 189– 201. The hippocampus, a component of the limbic system, is a prominent subcortical structure, which not only contains high concentrations of zinc, but also exhibits regional variations in this essential element, with concentrations being highest in the hilar region and lowest in the fimbria. For example, the concentration of zinc in the mossy fiber axons has been estimated to approach 300-350 microM. Both zinc and pyridoxal phosphate (PLP) deficiency and excess have been reported to produce epileptic form seizures, which are blocked by gamma-aminobutyric acid (GABA). The proposed mechanism is that at physiological concentrations zinc stimulates the activity of the hippocampal pyridoxal kinase (50% stimulation at 1.7 x 10(-7) M), enhancing the formation of PLP, whereas in pharmacological doses zinc inhibits the activity of glutamate decarboxylase (GAD) directly (50% inhibition at 6.5 X 10(-4) M) by preventing the binding of PLP to HoloGAD

It has long been suspected that the relative abundance of specific nutrients can affect cognitive processes and emotions. Newly described influences of dietary factors on neuronal function and synaptic plasticity have revealed some of the vital mechanisms that are responsible for the action of diet on brain health and mental function. Several gut hormones that can enter the brain, or that are produced in the brain itself, influence cognitive ability. In addition, well-established regulators of synaptic plasticity, such as brain-derived neurotrophic factor, can function as metabolic modulators, responding to peripheral signals such as food intake. Understanding the molecular basis of the effects of food on cognition will help us to determine how best to manipulate diet in order to increase the resistance of neurons to insults and promote mental fitness.

Thought: Prove to me that something is influential and interactive…but only by using the rules used to define effects in a singular, direct manner.
When you are faced with the problem of having to show a singular effect in order to prove it takes multiple influences to have an effect, this is called circular reasoning. It simply can’t be done. You can’t show truth by beginning with a false premise. In mathematics we create formulas based on observable facts in order to then test for the truth under new conditions. If the original formula for testing is based on an incomplete assumption it might just be the reason for the rifts in understandings and no clear picture for any of these disorders.
This exclusive reliance on a simplistic model of disease has limited and misled our understanding of human health from such factors as nutrition. Nutrition may not have a direct, singular or linear effect on health, not as we see the effects of germs or drugs….but nutrition has a much more over-reaching effect on things like gene expression, adaptive processes and the manifestation of complex disorders that resemble weather patterns in particular climates.

RECENT FINDINGS: Externalizing behavior is associated with both macromalnutrition (e.g. protein) and micromalnutrition (e.g. iron and zinc). Both prenatal and postnatal malnutrition is implicated. The long-term effects of malnutrition on behavior could be reversible. The effects of docosahexaenoic acid/omega-3 long-chain essential fatty acid on externalizing behavior are more mixed. From animal and human findings, it is hypothesized that malnutrition impairs neurocognitive functioning by reducing neurons, alternating neurotransmitter functioning, and increasing neurotoxicity, and that such neurocognitive impairments predispose to externalizing behavior.

In addition to being a thinking machine, the brain is also a flesh and blood organ that must comply with the laws of metabolism and physiology. Insight into both its ‘mental’ and ‘physical’ properties is vital for comprehending key aspects of brain health and function. … For it to participate in such mentally demanding endeavors, the brain would have relied on the prior existence of sophisticated neuronal circuitry. I suggest a nutritional basis for the dramatic cerebral expansion, with enhanced functionality (such as development of tool use and hunting strategy) being the natural responses of a larger, more plastic organ to novelty and environmental challenges. The common link between the evolutionary cerebral expansion and modern brain health/function resides in the massive wiring demands inherent in both processes. This marked amplification in neuronal connectivity is made possible by the enhanced production of synaptic membranes (nerve cell membranes in the regions of points of nerve cell contact).
How was it possible to fuel the production of major increases in neuronal number and synaptic density? This required the concordant expression of genetic potential (likely driven, in part, by the provision of an uninterrupted energy supply) and proper nutritional content – meaning high, sustained caloric and nutrient density. … persistent supply of nutrient dense calories is essential for brain expansion. To fully appreciate how energetically expensive brains are, consider that modern brains comprise about 2.3% of the body mass, yet consume almost one quarter of the available energy. Newborn brains utilize fully 75% of the body’s energy!

Thought: Why did we get rid of FAT from the diet anyway? My answer: Because the confines of Classical Physics and the 2nd Law of Thermodynamics dictates that the “only” direct linear effect of food on health (aka weight gain/obesity)was calories (calories in calories out).So…get rid of the highest caloric food group, aka FAT calories and you’d get rid of obesity….we’ve been travelling down the wrong path (singular blame) to health for a very long time because of our adherence to the wrong framework and ‘system’ of scientific thinking concerning human body and health…this is, in my opinion, the ‘crisis of perception’.

Thought: A sub-hypothesis: Could peripheral minds retain more minerals and therefore more metals than the general population?
One aspect of these minds having unique processing and more sensory information than the average is that they might also require more nutritional building blocks (neurotransmitters) for this information to be processed correctly and timely.
As we evolved, these individuals could have adapted to retain more nutritional resources from the foods they ate, and therefore became unique vessels for retaining minerals (such as Zinc, Selenium, Iron, Magnesium, Copper).
It could be hypothesized that if they retain these minerals at a higher rate, they would also retain METALS and mineral substrates at a higher rate than in the average population. These minerals might cause more damage by their own inherent toxicity and by blocking the essentially needed minerals for sensory processing. (Blocking and toxic agents such as Mercury, Fluoride, Aluminum, MSG, Cadnium, Lead).
(This is very over-simplified, but I think a good question to ask and a place to start, I think ultimately it will be much more complicated, such as different minerals may make individuals more susceptible to different metals at different times, ie, youth is a time for neural growth and as we age these needs shift to maintenance. This might require a different combination of resources, so in youth we may need more zinc, which would make us more susceptible to mercury, as we age we may need more selenium, which might make us more susceptible to aluminum…if there is shown to be a relation and interaction.)

The brain has the ability to change and morph with experience, “damaged” or lesser functioning areas can change with stimulation. (mainstream has always thought the brain was “set” in stone to more or less once through childhood)
EPIGENETICS (Wikipedia 2009)
In biology, the term epigenetics refers to changes in phenotype (appearance) or gene expression caused by mechanisms other than changes in the underlying DNA sequence (hence the name epi – “in addition to” – genetics). These changes may remain through cell divisions for the remainder of the cell’s life and may also last for multiple generations. However, there is no change in the underlying DNA sequence of the organism; instead, non-genetic factors cause the organism’s genes to behave (or “express themselves”) differently. The best example of epigenetic changes in eukaryotic biology is the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo which in turn become fully differentiated cells. In other words, a single fertilized egg cell – the zygote – changes into the many cell types including neurons, muscle cells, epithelium, blood vessels et cetera as it continues to divide. It does so by activating some genes while inhibiting others.

Dr. Pat Levitt: “…developmental neurobiologists spent an enormous amount of time trashing each others’ work because one was either in the “nature school” or the “nurture school” regarding brain development. Of course, that was silly because we know that the brain is built through a genetic blueprint that takes information from the outside world and utilizes it to direct the developmental course to wire up circuits. This gene–environment interaction is one of the unique properties of the brain. So, of course, regarding ASD, it is not genetic versus environmental, irrespective of whether you think there is a principal cause that is genetic or environmental. Because ASDs have at their core disrupted brain development, in terms of etiology, both genetic and environmental influences must play roles because this is in the basis for brain development.” ~Dr. Pat Levitt.

Thought: (There has been a strong and heated debate between Neurodiversity (ND) and Environmental-Damage (ED) advocacy groups. “Genes or Environment.”
I think in many ways they have been pitted against each other when in reality they have a common enemy: An out-dated mode of scientific thinking. ND is fighting the sociological confines and ED is fighting physiological confines of a disease model (GTD) and Classical Physics. ND is up against the Central Limit Theorem and ED is up against Koch’s Postulate. When creating this new framework it’s much easier to see that they may actually be on the same team, neuroatypical more readily damaged by neurotoxins resulting in neurological burdens or dysfunction.)

In a small study, the researchers tracked 30 men with low-risk prostate cancer who decided against conventional medical treatment such as surgery and radiation or hormone therapy. The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation.
After the three months, the men had changes in activity in about 500 genes — including 48 that were turned on and 453 genes that were turned off. The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences

Both androgens and glutamate alter neuronal and glial calcium oscillations, which are known to regulate cell migration, maturation, and final brain cytoarchitectural structure. Studies have also shown high levels of DHEA and low levels of DHEA-S in ASD, which can result from both mercury toxicity and chronic inflammation. Chronic microglial activation appears to be a hallmark of ASD. Peripheral immune stimulation, mercury, and elevated levels of androgens can all stimulate microglial activation. Linked to both transsulfuration problems and chronic mercury toxicity are elevations in homocysteine levels in ASD patients. Homocysteine and especially its metabolic products are powerful excitotoxins. Intimately linked to elevations in DHEA, excitotoxicity and mercury toxicity are abnormalities in mitochondrial function. A number of studies have shown that reduced energy production by mitochondria greatly enhances excitotoxicity.

Schizophr Bull 35: 256-278. The pathologic and behavioral abnormalities attributed to exposure to endocrine disruptors like bisphenol-A (BPA) have been studied in animals. Mental conditions ranging from cognitive impairment to autism have been linked to BPA exposure by more than one investigation. Concurrent with these developments in BPA research, schizophrenia research has continued to find evidence of possible endocrine or neuroendocrine involvement in the disease. Sufficient information now exists for a comparison of the neurotoxicological and behavioral pathology associated with exposure to BPA and other endocrine disruptors to the abnormalities observed in schizophrenia. …These similarities can be observed in 11 broad categories of abnormality: physical development, brain anatomy, cellular anatomy, hormone function, neurotransmitters and receptors, proteins and factors, processes and substances, immunology, sexual development, social behaviors or physiological responses, and other behaviors
Chen, CW. Assessment of endocrine disruptors: approaches, issues, and uncertainties. Folia Histochem Cytobiol. 2001;39 Suppl 2:20–23. This paper focuses on the quantitative risk assessment of environmental endocrine-disrupting chemicals (EDCs) to human health. An EDC can be defined as an exogenous agent that interferes with the normal endocrine signaling and communication mechanisms. The normal feedback control system of natural hormones is responsible for regulatory mechanisms that maintain homeostasis. Hormones deliver their message to target cells by interacting with receptors, initiating signal transduction, gene transcription, and mRNA translation, and ultimately leading to cellular response. Because effects of EDCs include diverse disease endpoints such as cancer, reproductive toxicity, developmental toxicity, immune system effects, acute toxicity, and neurotoxicity, risk assessment of EDCs is necessarily endpoint-specific. From the quantitative viewpoint, it is best to model the normal endocrinology and then extend the model to include impacts attributable to a particular exogenous agent

According to the Autism Society of America, autism is now considered to be an epidemic. The increase in the rate of autism revealed by epidemiological studies and government reports implicates the importance of external or environmental factors that may be changing. This article discusses the evidence for the case that some children with autism may become autistic from neuronal cell death or brain damage sometime after birth as result of insult; and addresses the hypotheses that toxicity and oxidative stress may be a cause of neuronal insult in autism

Grandjean P, Landrigan PJ Developmental Neurotoxicity of Industrial Chemicals. The Lancet, November 8, 2006- Vol. 368. Grandjean and co-author Philip J. Landrigan, Professor at Mount Sinai School of Medicine, compiled a list of 202 environmental chemicals known to be toxic to the human brain using the Hazardous Substances Data Bank of the National Library of Medicine and other data sources. (The authors note that the list should not be regarded as comprehensive; for example, the number of chemicals that can cause neurotoxicity in laboratory animal tests exceeds 1,000.) The authors then examined the published literature on the only five substances on the list—lead, methylmercury, arsenic, PCBs and toluene—that had sufficient documentation of toxicity to the developing human brain in order to analyze how that toxicity had been first recognized and how it led to control of exposure. They found a similar pattern in how the risks of each substance were documented: first, a recognition of adult toxicity and episodes of poisoning among children, followed by a growing body of epidemiological evidence that exposure to lower levels of the substances caused neurobehavioral deficits in children. “Even if substantial documentation on their toxicity is available, most chemicals are not regulated to protect the developing brain,” says Grandjean. “Only a few substances, such as lead and mercury, are controlled with the purpose of protecting children. The 200 other chemicals that are known to be toxic to the human brain are not regulated to prevent adverse effects on the fetus or a small child.”

Dr. Mark Noble: I think that if one wants to test the hypothesis that mercury is the primary causative agent in autism, that that is the wrong hypothesis. If one wants to test the hypothesis that mercury is one of many environmental factors that may contribute to this outcome that looks like the right hypothesis.
So if we look at what we can look at now, there is a limited number of agents where the sensitivity of analyses are sufficient to enable us to do reasonable studies, the organic materials, PCBs, a few other effects. That data may turn out to be extraordinarily compelling, particularly because of what we are hearing about the heavy metals and the chelation therapy. At least heavy metals are something that can be analyzed pretty well.
What I am specifically concerned with is that—with all respect and admiration and concern for the parents’ groups and everyone who has been trying to pursue the idea of a specific environment toxicant or a specific vaccination, just from a biological point of view, it doesn’t sound like a great hypothesis. It sounds like these may be pieces, that they happened at a particular time, but they are not going to apply to all the kids.
From the cell’s point of view, I don’t think it matters. Am I oxidized because of an inflammation? Am I oxidized because I got mercury? I don’t care, I’m oxidized, I am in electron deficit. The data that I am hearing just keeps agreeing with that. Even this idea of astrogliosis and the white-matter tracks, when we take these oligodendrocyte progenitors and expose them to oxidative stress, they turn into astrocytes. So even that is a really intriguing outcome. We have to look at specific astrocyte populations there.
So that is what I mean, that these all could be players. It doesn’t sound likely at this stage that any one of them is a player of central importance.

Potential contributions of environmental chemicals and conditions to the etiology of Autism Spectrum Disorders are the subject of considerable current research and speculation. The present paper describes the results of a study undertaken as part of a larger project devoted to the connection between properties of the indoor environment and asthma and allergy in young Swedish children. Results from the second phase of the DBH-study (DBH-II) indicate PVC flooring to be one important source of airborne phthalates indoors, and that asthma and allergy prevalence are associated with phthalate concentrations in settled dust in the children’s bedroom. Because these associations are among the few linking ASD with environmental variables, they warrant further and more extensive exploration….(Cone 2009) Vinyl flooring is commonplace in Sweden, where only about 1 percent of homes have carpeted floors. But it is uncommon in U.S. bedrooms, so it may not be related to autism among American children. However, carpeting contains other contaminants, including pesticides and brominated flame retardants, which have been found to harm brain development in animal tests. The scientists said their new finding “suggests that studies of other chemical contaminants with endocrine disruptor properties might yield useful insights into the genesis of autism. http://www.environmentalhealthnews.org/ehs/news/autism-and-vinyl-flooring

Pall M. L. (2002) NMDA sensitization and stimulation by peroxynitrite, nitric oxide and organic solvents as the mechanism of chemical sensitivity in multiple chemical sensitivity. FASEB J, 16,1407-1417. Multiple chemical sensitivity (MCS) is a condition where previous exposure to hydrophobic organic solvents or pesticides appears to render people hypersensitive to a wide range of chemicals, including organic solvents. The hypersensitivity is often exquisite, with MCS individuals showing sensitivity that appears to be at least two orders of magnitude greater than that of normal individuals. This paper presents a plausible set of interacting mechanisms to explain such heightened sensitivity. It is based on two earlier theories of MCS: the elevated nitric oxide/peroxynitrite theory and the neural sensitization theory. It is also based on evidence implicating excessive NMDA activity in MCS. Four sensitization mechanisms are proposed to act synergistically, each based on known physiological mechanisms: Nitric oxide-mediated stimulation of neurotransmitter (glutamate) release; peroxynitrite-mediated ATP depletion and consequent hypersensitivity of NMDA receptors; peroxynitrite-mediated increased permeability of the blood–brain barrier, producing increased accessibility of organic chemicals to the central nervous system; and nitric oxide inhibition of cytochrome P450 metabolism. Evidence for each of these mechanisms, which may also be involved in Parkinson’s disease, is reviewed. These interacting mechanisms provide explanations for diverse aspects of MCS and a framework for hypothesis-driven MCS research

Walsh WJ, Rehman F. Methylation syndromes in mental illness. Abstract, Neuroscience Society. New Orleans; Nov. 1997.
Methylation: Rich van Konynenburg’s idea is that ineffective methylation is a major cause of fatigue. There are many possible reasons but those that he’s identified for which methylation is essential to are:
- To produce vital molecules such as Co Q-10 and carnitine.
- To switch on DNA and switch off DNA. This is achieved by activating and deactivating genes by methylation. This is essential for gene expression and protein synthesis. Proteins of course make up the hormones, neurotransmitters, enzymes, immune factors and are fundamental to good health. When viruses attack our bodies, they take over our own DNA in order to replicate themselves. If we can’t switch DNA/RNA replication off then we will become more susceptible to viral infection.
- To produce myelin for the brain and nervous system.
- To determine the rate of synthesis of glutathione which is essential for detoxification.
- To determine the rate of synthesis of glutathione which is an essential anti-oxidant as glutathione-peroxidase. Furthermore oxidative stress blocks glutathione synthesis – yet another vicious cycle!
- To control sulphur metabolism of the body, not just glutathione but also cysteine, taurine and sulphate. This is an important process for detoxification.
- As part of folic acid metabolism. This also switches on synthesis of new DNA and RNA.
- For normal immune function. The methylation cycle is essential for cell mediated immune function and blockages here will mean that infections will not be adequately dealt with. I know this clinically because many patients tell me that once they get on to their B12 injections (an essential co-factor for methylation) this seems to protect them from getting infections.
The overall effect here is that if the methylation cycle doesn’t work, the immune system mal-functions, the detoxification system mal-functions, our ability to heal and repair is reduced and the anti-oxidant system mal-functions. ~ (Dr. Sarah Myhill www.drmyhill.co.uk)

“if the mechanistic information concerning hormone action that we review here had been considered, the currently accepted practice of only testing very high doses to predict effects of doses thousands or even millions of times lower would have been recognized to be inappropriate. The result would have been that doses of EDCs, such as methoxychlor and bisphenol A, far below those currently being described as “safe” would, in fact, have been predicted to produce biological responses, and much lower doses would have been tested.”
In a non-monotonic dose response curve (NMDRC) , the shape of the dose response curve reverses as the level of contamination goes up. Some NMDRC are shaped like U’s, with high responses at low and at high levels of contamination. Others are shaped like inverted U’s with the greatest response in intermediate ranges. The puzzling but observable fact is that low doses may actually cause greater impact than high doses for a specific response.
Welshons et al. interprete this in the following way: At high doses, the contaminant is overtly toxic, poisioning the system and hence (in the example below), causing shrinkage of the prostate. At an intermediate dose (but very low dose… in the example below 0.2 parts per billion), DES turns on genes that stimulate prostate growth.

The essence of my (Dr. Vijendra Singh) “Autoimmune Hypothesis” is that a virus-induced autoimmune response to developing brain myelin may impair anatomical development of neural pathways in autistic children. This line of thinking relies on the fact that the speed of nerve-impulse transmission depends essentially on structural properties of the insulating myelin sheath, connecting nerve fibers, and axon diameter. The anatomical changes could ultimately lead to life-long disturbances of higher mental functions such as learning, memory, communication, social interaction, etc.

To conclude, since everything changes with time, I firmly believe that it is time to re-evaluate the safety of vaccines and the manner in which we practice immunizations. Vaccines are well known to cause numerous adverse reactions in humans and no matter how rare they might be it is time to pay a closer attention to them. I don’t think the epidemiological studies will suffice the purpose but the laboratory-based experimental research is urgently needed. We need new policies simply because the existing policies are not in line with our modern knowledge of human immunology, virology, and genomics. This is clearly exemplified by our experimental approach involving laboratory techniques that did not exist 30-40 years ago when the vaccines were originally developed. Indeed, there is persuasive evidence to suggest that the MMR vaccine could potentially cause autism or a regressive form thereof in a significant number of children. At this juncture, I would also like to recommend a new policy of “Testing immunity before vaccination or immunization” that should help identify immunocompromised children who otherwise might react adversely to vaccines. The cost should not deter us from implementing this policy especially when the lives of hundreds and thousands of children and their families are concerned.

Could we also be asking the question: Is it vaccines or has the deterioration of our environment and nutrition created a situation where these individuals no longer have the capability or resources to recover from the stress of vaccines? Or is it a combination of both? Is it that vaccines now cause too much of a “distraction” of resources from myelination and brain processing development and adequate neuro-functioning? (*note: thinking in terms of variability, cumulative, ecosystem impairment….vaccines might merely be the most effective way to cause impairment within particular systems already under heavy burdens and predisposed neurophysiology that would directly and indirectly lead to the manifestation of symptoms)
And is this analogous to idea of sun damage…did we become “allergic” to the sun is the source of life on earth? Or is our inability to repair from the sun’s natural ‘damage’. A result of our depleted resources, such as antioxidants and Omega-3 fats? Is this a combination of the ozone(additional stress) and our lack of proper nutrition to repair? Wouldn’t the solutions come full circle, back to addressing our environment and the nutritional quality of our food/resources?

In toto, there is strong circumstantial evidence from both experimental and clinical studies to support a role for omega-3 FA in the prevention of non-melanoma skin cancer (NMSC). In experimental animal studies there is direct evidence that dietary omega-3 FA inhibits ultraviolet radiation (UVR) carcinogenic expression, with regard to both increased tumor latent period and reduced tumor multiplicity. Equivalent levels of omega-6 FA increase UVR carcinogenic expression. Dietary omega-3 FA dramatically reduces the plasma and cutaneous pro-inflammatory and immunosuppressive PGE(2) levels in mice. Dietary omega-6 FA increases prostaglandin E synthase type 2 (PGE(2)) level. Dietary omega-3 FA significantly reduces the inflammatory response and sustains, or enhances, the delayed type hypersensitivity immune response in mice when compared to an equivalent dietary level of omega-6 FA. Supplementary omega-3 FA significantly increases the UVR-mediated erythema threshold in humans. Supplementary omega-3 FA significantly reduces the level of pro-inflammatory and immunosuppressive PGE(2) levels in Ultraviolet B-irradiated human skin.

OBJECTIVE: This article reviews recent developments in cytokine biology that are relevant to clinical psychiatry. METHOD: The authors reviewed English-language literature of the last 15 years that pertains to the biology of cytokines with emphasis on central nervous system effects in general and psychiatric disorders in particular. RESULTS: Growing evidence suggests that, in addition to providing communication between immune cells, specific cytokines play a role in signaling the brain to produce neurochemical, neuroendocrine, neuroimmune, and behavioral changes. This signaling may be part of a generalized, comprehensive mechanism to mobilize resources in the face of physical and/or psychological stress and to maintain homeostasis. The clinical implications of these findings are far-reaching and include a possible role for cytokines in the pathophysiology of specific psychiatric disorders such as major depression, schizophrenia, and Alzheimer’s disease. The effects of cytokines in the central nervous system may provide a possible mechanism for the “sickness behavior” of patients with severe infection or cancer, as well as for the neuropsychiatric adverse effects of treatment with interferons and interleukins.CONCLUSIONS: A better understanding of the role of cytokines in various brain activities will enhance knowledge of specific psychobiological mechanisms in health and disease and provide opportunities for novel treatment interventions.

In the past, Ohio State University (osu.edu 2009) researchers have discovered that:
Chronic stress can weaken the immune status of caregivers to the extent that they are more susceptible to the onset of some diseases;
High levels of psychological stress can slow the process of wound healing to such an extent as to increase the risks of recovery in procedures ranging from minor dental procedures to major surgery;
Vaccines given to protect against both bacterial and viral diseases may be impaired if the inoculations are given when a person is highly stressed;
Even in people who are normally considered to be “happy”, the effects of minor psychological stress can have health impacts.

Even when these patients are coming into the clinic looking pretty healthy, they have evidence of extra metabolic stress,” Enns said, noting the findings were surprising because none of the patients were in the midst of a health crisis such as organ failure when blood samples were taken. It is the first time such signs have been uniformly shown in the blood of patients across a wide range of mitochondrial disorders, he added.
The team saw that levels of glutathione, the body’s primary antioxidant, were significantly reduced in white blood cells from the 20 mitochondrial disease patients in the study. The observation means patients’ antioxidant defenses were indeed depleted.

The Role of Emotion
I think we too often dismiss emotions as irrelevant, inconvenient “noise”, or even just a character flaw, when these emotions serve a purpose; as protection, guidance, and inspiration.
Take a look at dendrites, the computer programming of the brain. Dependent upon energy (ATP), neurochemicals, and electricity to create this wondrous and beautiful network of connecting branches. Every time we start a memory, learn a skill, build a neural pathway, this is what our brain kicks into gear. It builds a neuronet for every occasion, every moment…all day, every day. And it tries to finish and connect each and every one (remaining consistent and complete). This is how, as infants, we learn coordination, learn our environment, what to do, what not to do, it’s how we get “programmed”. We get constant feedback and each neuronet builds upon the previous forest built by our experience. (could be an indication for an increased susceptibility to PTSD?)

Mammals and birds have evolved three primary, discrete, interrelated emotion-motivation systems in the brain for mating, reproduction, and parenting: lust, attraction, and male-female attachment. Each emotion-motivation system is associated with a specific constellation of neural correlates and a distinct behavioral repertoire. Lust evolved to initiate the mating process with any appropriate partner; attraction evolved to enable individuals to choose among and prefer specific mating partners, thereby conserving their mating time and energy; male-female attachment evolved to enable individuals to cooperate with a reproductive mate until species-specific parental duties have been completed.

Terence Ketter, MD, professor of psychiatry and behavioral sciences and a study co-author, said he became interested in the link between mental illness and creativity after noticing that patients who came through the bipolar clinic, despite having problems, were extraordinarily bright, motivated people who “tended to lead interesting lives.” He began a scholarly pursuit of this link and in 2002 published a study that showed healthy artists were more similar in personality to individuals with bipolar disorder (the majority of whom were on medication) than to healthy people in the general population. Some researchers believe that bipolar disorder or mania, a defining symptom of the disease, causes creative activity. Ketter said he believes that bipolar patients’ creativity stems from their mobilizing energy that result from negative emotion to initiate some sort of solution to their problems. “In this case, discontent is the mother of invention,” he said.

Momentary lapses in attention frequently impair goal-directed behavior, sometimes with serious consequences. Nevertheless, we lack an integrated view of the brain mechanisms underlying such lapses. By investigating trial-by-trial relationships between brain activity and response time in humans, we determined that attentional lapses begin with reduced prestimulus activity in anterior cingulate and right prefrontal regions involved in controlling attention. Less efficient stimulus processing during attentional lapses was also characterized by less deactivation of a ‘default-mode’ network, reduced stimulus-evoked sensory activity, and increased activity in widespread regions of frontal and parietal cortex. Finally, consistent with a mechanism for recovering from attentional lapses, increased stimulus-evoked activity in the right inferior frontal gyrus and the right temporal-parietal junction predicted better performance on the next trial. Our findings provide a new, system-wide understanding of the patterns of brain activity that are associated with brief attentional lapses, which informs both theoretical and clinical models of goal-directed behavior.

This is important because larger synapses consume a lot of energy, occupy more space and require more supplies, including the proteins examined in this study. Sleep — by allowing synaptic downscaling — saves energy, space and material, and clears away unnecessary “noise” from the previous day, the researchers believe. The fresh brain is then ready to learn again in the morning.

Ernest Rossi with his ground-breaking work with what he calls Ultradian Rhythms.
His research in these rhythms discusses how the brain depletes essential neurochemicals and needs “restoration breaks” on particular rhythms during the course of the day. This gives us the understanding that these resources can be depleted and need constant attention to function at an optimal rate as to not engage “stress modes” of the mind and body.
Western medical scientists are world class experts, exceedingly precise and astonishingly accurate with their work and knowledge. To borrow a phrase, Not Even Wrong, because they are not wrong. In fact, in their unrelenting adherence to the principals of those methods (of Classical Physics and modern medicine) that we can say and believe with utmost certainty that Autism and related disorders have nothing inherently wrong (or single cause). Which is why there are still experts who will contend, that within their scientific framework, Autism, Fibromyalgia, Personality disorders, etc. “don’t really exist”(as diseases) because existing in that scientific model means “a single organic cause” or something wrong to begin with (genetic disease). The acceptance that these disorders exist at all, is because we cannot deny the presence of such profound symptoms and sometimes, sometimes only because individuals and parents have not and would not allow them to be ignored.

“Thoughtful leaders increasingly recognize that we are not only failing to solve the persistent problems we face, but are in fact causing them. System dynamics is designed to help avoid such policy resistance and identify high-leverage policies for sustained improvement. What does it take to be an effective systems thinker, and to teach system dynamics fruitfully? Understanding complex systems requires mastery of concepts such as feedback, stocks and flows, time delays, and nonlinearity. Research shows that these concepts are highly counterintuitive and poorly understood. It also shows how they can be taught and learned. Doing so requires the use of formal models and simulations to test our mental models and develop our intuition about complex systems. Yet, though essential, these concepts and tools are not sufficient. Becoming an effective systems thinker also requires the rigorous and disciplined use of scientific inquiry skills so that we can uncover our hidden assumptions and biases. It requires respect and empathy for others and other viewpoints. Most important, and most difficult to learn, systems thinking requires understanding that all models are wrong and humility about the limitations of our knowledge. Such humility is essential in creating an environment in which we can learn about the complex systems in which we are embedded and work effectively to create the world we truly desire.”

So, what is a system? A system is a set of things—people, cells, molecules, or whatever—interconnected in such a sway that they produce their own pattern of behavior over time. The system maybe buffeted, constricted, triggered, or driven by outside forces. But the system’s response to these forces is characteristic of itself, and that response is seldom simple in the real world….The system, to a large extent, causes its own behavior! An outside event may unleash that behavior, but the same outside event applied to a different system is likely to produce a different result. (p.34)…You’ll be thinking not in terms of a static world, but a dynamic one. You’ll stop looking for who’s to blame; instead you’ll start asking “What’s the system?”
IF WE CAN BEGIN TO USE THE SCIENCE OF ECOSYSTEMS AND SUSTAINABILITY, WE MAY BEGIN TO UNRAVEL THE MYSTERIES OF AUTISM.
It is the conclusion of this theory that our science, our environment, our mistaken interpretations, and our well intentioned but misguidance of nutrition information, environmental influences (chemicals), our educational standardization (assumptions of normal) and our communities (competiveness and comparisons) have created these unbalanced and unhealthy outcomes. Changing our understanding of the human body to an ecosystem scientific framework that interacts, is challenged and intimately influenced by our environment, nutrition, attitudes, economic motivations, community, and educational expectations will guide our future endeavors and begin to correct our mistakes of the past.
