Overview
Autism spectrum disorder (ASD) is a developmental disorder that affects communication, social interaction, behavior, and sensory processing.
It's called a "spectrum" disorder because it can vary widely in its presentation and severity, ranging from mild to severe.
Causes
Some common characteristics of ASD include difficulties in social interaction, such as understanding social cues and nonverbal communication, challenges in forming relationships, repetitive behaviors or rituals, intense interests in specific topics, and sensory sensitivities.
