ASD
Autism, also known as autism spectrum disorder (ASD), is a condition characterized by differences or difficulties in social communication and interaction, a need or strong preference for predictability and routine, sensory processing differences, focused interests, or repetitive behaviors. Features of autism are present from early childhood and the condition typically persists throughout life. Autism is classified as a neurodevelopmental disorder, and a formal diagnosis requires professional assessment that these characteristics cause significant challenges in daily life beyond what is expected given a person's age and social environment. Because autism is a spectrum disorder, presentations vary and support needs range from minimal to the person being non-speaking or needing 24-hour care.
