A new collection stores genetic and behavioral information about children with autism in inpatient psychiatric units.

Electrically stimulating a particular circuit in the brain shows promise for reversing symptoms of Rett syndrome, a disorder that shares features with autism.

Researchers have defined a new syndrome that results from carrying two mutated copies of CNTNAP2, a gene linked to autism.
