A team at the Children's Hospital in Philadelphia, supported by grants from the NIH, Autism Speaks, and others, have used magnetic signals from brain activity to discover that children with autism spectrum disorders process sound a fraction of a second slower than their peers.
So far, doctors have relied on anecdotal evidence and non-concrete patterns like speech development to recognize autism spectrum disorders. With refinement, this finding may provide an objective biological measurement for diagnosis.
