Autism Spectrum Disorder

To define Autism Spectrum Disorder: Autism Spectrum Disorder involves differences in social communication and repetitive behaviors, with unique sensory experiences and varying support needs.

Overview

Description

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by persistent deficits in social communication and social interaction across contexts, along with restricted, repetitive patterns of behavior, interests, or activities. Sensory sensitivities and differences in processing are common. Presentation and support needs vary widely across individuals and over time.

Prevalence

Estimates vary by region and methodology; ASD is commonly identified in childhood and may be underrecognized in females and adults.

Age of Onset

Symptoms emerge in early childhood, though recognition may occur later as social demands increase.
