In it's own medically quite fast way, the discussions related to the link between Mitochondrial Disorders and Autism Spectrum Disorders are gaining traction. There is meeting to discuss the same at the UMDF conference in Indianapolis on June 29. As I had posted earlier, this is a natural conclusion of limit theorem and this is the only known case of a particular disease causing an autism spectrum disorder as opposed to "no reason" that usually accompanies autism. So this is definitely something worth a discussion.
Meanwhile, a research team in Korea has found another possible triggerchemical in the brain that can cause Autism Spectrum Disorders. This is the area in the brain that carries out primitive emotions.
