"Researchers at the University of Leicester, working with the NHS Information Center found that roughly 1 in 100 adults are on the spectrum — the same rate found for children in England, Japan, Canada and, for that matter, New Jersey."

"However, the most interesting finding is that only the children with Asperger’s showed more brain mass in an area called the right supramarginal gyrus, which is an area of the brain that has been associated with social cognition, including theory of mind"

Fascinating. "While mean velocities of 5HTT kinetics did not significantly differ among the groups, significant elevation in the mean velocity of MAOB kinetics was observed in NS subjects and was even more pronounced in HS subjects in comparison to controls. Also, a decrease in adenosine 50 -diphosphate-induced platelet aggregation of borderline significance was observed in NS subjects, compared to C subjects. The results suggest a possibility of upregulation of monoaminergic synthesis/ degradation and, probably consequential, downregulation of 5HT2Ar in autistic subjects."

Linking this due to a comment about diagnostic substitution: "the 5% highest scorers were assessed as possessing ‘extreme autistic-like traits’ and “Around 10% of all children showed only social impairment, only communicative difficulties or only rigid and repetitive interests and behavior, and these problems appeared to be at a level of severity comparable to that found in children with diagnosed ASD in our sample” ( Plomin et al 2006 ( MEDLINE ) Plomin et al 2006 page 1218 ( MEDLINE ) ). Does 10% of the entire population have an ‘Autism Spectrum Disorder”? Japanese schizophrenia researchers applied the Broad Autism Phenotype Questionnaire (BAPQ) to a group of patients diagnosed with either schizophrenia or schizoid personality disorder (A broad schizophrenia phenotype). All participants scored higher than the cutoff points in the BAPQ test."

Coping mechanisms again. "You may have noted however, that children with autism had greater fractional anisotrophy in two areas (superior fasciculus and left occipital lobe). The authors argued that this finding may be due to increase use of brain regions involved in working memory and visual processing. Therefore, these findings may reflect brain correlates of advanced non-verbal strategies used by individuals with autism to process verbal information."

Does diagnostic substitution explain increases in autism diagnosis? Not likely in California - Child Psychology Research Blog - http://www.child-psych.org/2009...
"The authors stated that these findings are consistent with other recent examinations of emotion recognition deficits in autism that suggest that such deficits are more related to general cognitive deficits rather than the presence of autism."

"With this new fine-grained data, the researchers were able to reach the conclusion that training leads to gains of efficiency in the central processing module within the IFJ. The degree of improvement in reaction time corresponded to the acceleration in IFJ processing as revealed by fMRI. This shows that, even though the brain is massively parallel, complicated behaviors must pass through this bottleneck before they can be executed."

"Perhaps the real problem is attempting to lump all these behavioral problems into the basket of clinical dependence. No one denies that some children play too many video games or that MDMA abuse is a serious problem for some individuals. But does it make sense to classify a college kid spending too much time on Facebook in the same category as a woman who lives on the street and sells her body to support a heroin habit? Can our definitions of addiction and our social deterrents against it actually cause more harm than they prevent?"

"Autism is thought to be associated with a bias towards detail-focussed processing. While the cognitive basis remains controversial, one strong hypothesis is that there are high processing costs associated with changing from local into global processing. A possible neural mechanism underlying this processing style is abnormal neural connectivity; specifically reduced structural or functional connectivity between brain regions might lead to good exemplar-based processing but poor generalisation." Of course, exceptional local detail focus and a bias towards repetitive complex actions could be a huge asset in some situations. There could be plenty of high-functioning autistic spectrum people out there right now that have just found a niche that works for them.
