Autism: Symptoms & Signs

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. Children with ASD who have not developed sufficient language skills may act out, including screaming or crying, to express their needs. It is important to note that people with ASD may vary widely in their level of functioning, and not all people with ASD will experience all of the symptoms listed.

Early symptoms and signs in babies may vary but can include lack of eye contact or decreased eye contact, being overly focused on one item, and lack of back-and-forth play. Very young children may show early symptoms like loss of interest in social contact and social withdrawal.
