Understanding Autism

Autism, also called autism spectrum disorder (ASD) in many clinical and public-health settings, is a developmental disability and a form of neurodivergence. It can influence communication, sensory experiences, learning, movement, routines, interests, and social interaction. Autistic people have varied strengths, support needs, and life experiences.

Why is it called a spectrum?

Spectrum does not mean everyone is on one simple line from “mild” to “severe.” People have different combinations of strengths and challenges, and support needs can vary by setting and over time. Some communicate with speech, some use augmentative and alternative communication, and some use multiple ways to communicate.

Autism across the lifespan

Autism is lifelong, although needs, environments, and preferred supports may change. Some people are identified in early childhood; others receive an evaluation as teenagers or adults. A person's outward appearance does not tell you whether they are autistic.

Acceptance and practical inclusion

• Ask how a person prefers to communicate and what accommodations help.
• Respect sensory needs, communication differences, movement, and routines.
• Offer clear information, predictable expectations, and accessible choices.
• Do not assume every autistic person has the same abilities or preferences.
• Include autistic people in decisions that affect their lives.

Language and identity

Many prefer identity-first language such as “autistic person”; others prefer person-first language such as “person with autism.” Follow the individual's preference where known. Avoid language that treats autistic people as broken or measures their worth by how non-autistic they appear.
