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 two years of life. ASD is known as a "spectrum" disorder because there is wide variation in the type and severity of symptoms people experience. Learn more about autism spectrum disorder.
