Blood hints at autism’s source

From San Diego, at the Experimental Biology 2005 meeting

Researchers have identified a biochemical peculiarity in the blood of autistic children. The scientists say the finding could lead to earlier diagnosis of this neurological disorder and a better understanding of how certain genes may drive it.

Autism, which typically shows up in toddlers, is characterized by limited language skills, poor social interaction, repetitive behaviors, and limited interests.
