Symptom Checker: Symptoms & Signs Index
Medical Author: Melissa Conrad Stöppler, MD
Autism spectrum disorder (ASD) is a range of neurodevelopmental disorders predominantly characterized by impaired social functioning and communication disturbances. Symptoms can include intense focus on one item, unresponsiveness, lack of understanding social cues (like tone of voice or body language), repetitive movements, or self-abusive behavior like head-banging. The severity of the symptoms varies widely among affected individuals. Other possible symptoms include learning to speak relatively late, not playing interactively with other children, avoidance of eye contact, lack of empathy, and social withdrawal.
