What is Autism Spectrum Disorder?

Autism spectrum disorder (ASD) is a developmental disorder that affects a person’s ability to socialize and communicate with others. ASD can also result in restricted, repetitive patterns of behavior, interests, or activities. The term “spectrum” refers to the wide range of symptoms, skills, and levels of impairment or disability that people with ASD can have. Because these symptoms and behaviors lie on a spectrum, no two autistic people are the same.
