Autism—often called autism spectrum disorder (ASD) —is a lifelong neurodevelopmental difference that affects how a person communicates, interacts with others, and experiences the world.123
What the "Spectrum" Means
- Unique combinations: Autism is not a straight line from "mild" to "severe". Instead, it means each autistic person has a unique mix of strengths, challenges, and support needs.12
- Support levels: Some autistic people live completely independently, while others need substantial, daily support.123
- Lifelong identity: Autism is present from birth (or early childhood) and is an inherent part of a person's identity rather than an illness or disease.123
Core Characteristics
- Social communication: Differences in how people converse, read non-verbal cues (like eye contact or body language), or build relationships.123
- Routine and focus: A strong preference for routines, predictability, or deep, focused interests in specific topics.123
- Sensory processing: Heightened or lowered sensitivity to lights, sounds, smells, tastes, or textures.123
- Stimming: Using repetitive movements or sounds (such as hand-flapping, rocking, or pacing) to self-regulate, express joy, or cope with overstimulation.12
Common Co-Occurring Conditions
- Many autistic people also experience conditions like ADHD, anxiety, depression, epilepsy, or specific learning differences like dyslexia.
- Around a third of autistic people also have a general learning disability, though many have average or above-average intelligence.1234
