Autism is a complex neurodevelopmental concept and research domain focused on understanding a specific profile of human variation characterized by differences in social communication and interaction, and restricted, repetitive patterns of behavior, interests, or activities, often with sensory sensitivities. Academic investigation within this domain explores its diverse etiology, neurobiological underpinnings, cognitive profiles, developmental trajectories across the lifespan, and the development of effective supports and strategies for inclusion and well-being, contributing significantly to the understanding of neurodiversity.
