Autism Spectrum Disorder (ASD)

Autism is a complex neurobiological disorder that typically appears during the first three years of life and lasts throughout a person’s lifetime. It is a spectrum disorder with a wide range of characteristics ranging from mild to severe. Individuals with ASD demonstrate difficulties in social interaction, communication, and behavior. Each person displays communication, social, and behavioral patterns that are unique to the individual but fit into the overall diagnosis of ASD. There are five primary diagnostic terms that fall under the Autism Spectrum Disorder heading: Autism, Asperger's Syndrome, PDD-NOS, Rett's Syndrome, and Childhood Disintegrative Disorder. While each shares common characteristics, there are differences that distinguish one diagnosis from another. For more complete information on "What is Autism Spectrum Disorder?" visit:
