What is autism spectrum disorder? Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication, and behavioral challenges. The term âspectrumâ refers to the wide range of symptoms, skills, and levels of impairment that people with ASD can have. ASD affects people in different ways and can range from mild to severe. People with ASD share some symptoms, such as difficulties with social interaction, but there are differences in when the symptoms start, how severe they are, the number of symptoms, and whether other problems are present. The symptoms and their severity can change over time. The signs of ASD begin in early childhood, usually in the first 2 years of life, although a small minority of children may show hints of future problems within the first year of life.
