VIDEO: Dr. Eric Courchesne explains the underlying brain biology of autism

A small study by Dr. Eric Courchesne found that male children with autism had larger brain weights and 67% more prefrontal brain neurons than children without autism.Dr. Eric Courchesne, keynote speaker at IMFAR 2011, describes the underlying brain biology of autism and shares new findings showing differences in brain structure in people with autism. These changes originate in the second trimester of prenatal life when there is a tremendous overproduction of brain cells in individuals with autism that create patches of functional abnormality. Dr. Courchesne describes how early intervention alters brain connections and structure, and discusses the “recovery genetics” of autism, including new understanding about why some kids recover from autism while other children continue to struggle.
