Demographic information and summary statistics by diagnosis. Note: the ASD group is comprised of individuals diagnosed with all formerly used DSM-IV-TR subtypes, including 289 (66.1%) individuals diagnosed with Autism, 73 (16.7%) individuals diagnosed with Asperger's, 25 (5.7%) individuals diagnosed with Pervasive Development Disorder, and three (0.7%) individuals diagnosed as ASD-Not Otherwise Specified. DSM-IV-TR subtype information was not provided for 47 (11%) of ASD patients. Asymmetry values are non-directional.
