Signs and symptoms

Autism spectrum disorder (ASD) is a developmental disorder characterized by differences in social interaction and communication as well as the presence of restricted and repetitive patterns of behavior, interest or activities. People who have ASD may experience a range of symptoms and characteristics. Some people may have very noticeable characteristics, others may not. ASD may be diagnosed as early as 18 to 24 months, but can be diagnosed at any age. The earlier treatment and intervention begins, the more effective the outcomes.
