Young children with autism appear more likely to have enlarged amygdala - the part of the brain associated with registering faces and with expressing key emotions, according to a study released on Monday.
Described in the May issue of Archives of General Psychiatry, the study compared the magnetic resonance imaging (MRI) results of 50 autistic children and 33 control children.
The children's brain scans were taken at age two and again at age four.
