Key Brain 'Networks' May Differ in Autism

Neural systems tied to gauging social cues appear 'over-connected' in children with the disorder

"The differences haven't always been consistent. We still don't yet understand what causes autism, nor do we have a great handle on how the brain of those with autism differs," he explained.

"What they found was that this excess connectivity is more common in those with more severe symptoms," Adesman said. However, "they are not sure if this is a chicken or egg [finding]."

The researchers agree, noting that they can't establish cause and effect. In essence, it's possible that the abnormal social development of children with an autism spectrum disorder may lead to the connectivity differences, they said, not the other way around.

Fishman said her team is planning further study, however. She said that if the findings are replicated, there might be a way to tweak the neural networks to bring them closer to that of children without an autism spectrum disorder.
