What is Autism?
Autism is a difference in how a person’s brain works and experiences the world. It can affect communication, sensory experiences, learning styles, and daily life. There is not just one definition of autism. Some definitions come from medical or diagnostic systems, while others come from Autistic people and focus on lived experience and identity.
Ways Autism is Defined and Understood
Autism is described in different ways depending on who is defining it and why. Definitions used in healthcare, research, law, and service systems may focus on diagnosis or eligibility, while definitions from Autistic people and advocacy organizations may emphasize lived experience, identity, strengths, barriers, and support needs. The sources below offer different perspectives on what autism is and how it is understood.

Autism and Disability Language
Words matter. The language used to describe autism and disability can affect whether people feel respected, understood, and included. Autistic people may have different preferences for how they describe themselves. Some prefer “Autistic person,” others prefer “person with autism,” and some use both. There is no single choice that fits everyone. When possible, use the language a person prefers. If you do not know, it is okay to ask.
Language also changes over time. Some terms that were once commonly used may now be considered outdated, inaccurate, or harmful. Autistic people, families, caregivers, professionals, and organizations may also use different language based on their experiences and perspectives. KYACA values these perspectives while supporting each person’s right to have a voice in how they are described.
