TheDiagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV; American Psychiatric Association, 1994) defines Pervasive Developmental Disorders (PDD) as those syndromes which are characterized by severe and pervasive impairment of reciprocal social skills, communication, or the presence of stereotyped interests and activities. Included under PDD are Autism, Rett's disorder, childhood disintegrative disorder, Asperger's Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). To date, detailed neuroanatomic studies have been initiated in only two of these disorders, Autism and Rett syndrome (RS) and some very preliminary data are available for Asperger syndrome (AS).
