Brain Scans Detect Autism’s Signature

Published November 16, 2010 in Science Daily

An autism study by Yale School of Medicine researchers using functional magnetic resonance imaging (fMRI) has identified a pattern of brain activity that may characterize the genetic vulnerability to developing autism spectrum disorder (ASD). The team identified three distinct “neural signatures”: trait markers — brain regions with reduced activity in children with ASD and their unaffected siblings; state markers — brain areas with reduced activity found only in children with autism; and compensatory activity — enhanced activity seen only in unaffected siblings. The enhanced brain activity may reflect a developmental process by which these children overcome a genetic predisposition to develop ASD.
