Autism, or autism spectrum disorder (ASD), is a neurodevelopmental disorder marked by difficulties in social skills, communication, and sensory sensitivities, typically identified in early childhood. The DSM-5 categorizes autism by its characteristics, emphasizing the spectrum of challenges and strengths, with a prevalence of about 1 in 68 children in the U.S. Effective interventions range from behavioral programs to specialized therapies aimed at improving communication, social skills, and overall quality of life for those with autism.
