Autism Spectrum Disorder (ASD)

Autism spectrum disorder 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.  

Autism is known as a “spectrum” disorder because there is wide variation in the type and severity of symptoms people experience. ASD occurs in all ethnic, racial, and economic groups. The latest Centers for Disease Control and Prevention analysis estimates that one in 44 children have ASD.

People with autism have a wide range of symptoms, which can include differences in social and communication behaviors, intellectual disabilities, and other physical and mental health conditions. People with autism also have a wide range of health care and service needs. Research shows that access to needed services and support early in life can promote people’s health and well-being over the long term.
