What is Autism?

Autism spectrum disorder (ASD) is a neurological and developmental disorder that affects how people interact with others, communicate, learn, and behave. Although autism can be diagnosed at any age, it is described as a “developmental disorder” because symptoms generally appear in the first 2 years of life.

The Features of Autism Spectrum Disorder

The Centers for Disease Control and Prevention (CDC) refers to The American Psychiatric Association’s Diagnostic and Statistical Manual, Fifth Edition (DSM-5) to provide standardized criteria to help diagnose ASD as graphically displayed above.

The DSM 5 uses a level system within diagnosis to determine/ predict the level of support the individual will need; the lowest level of support beginning with requiring support at level 1 to requiring very substantial support at level 3.
