Now Arkansas Children's Hospital Research Institute researchers report for the first time that children with autism have a severely abnormal metabolic profile indicating increased vulnerability to oxidative stress. The scientists also identified a significant increase in the frequency of several genetic polymorphisms that they believe may increase the risk of autism in specific combinations yet to be determined.  more
