Autism spectrum disorders affect the way the brain works, leading to a range of behavioral and social disabilities that range from very mild to severe. Children with autism spectrum disorders have problems communicating and interacting socially. They also have repetitive behaviors, interests, and activities. About one-third of children with autism spectrum disorders have intellectual disability.

Children with developmental disorders often have problems with attention, memory, cognition, language, problem-solving, or social interaction. These problems can range from mild to severe and can be easily managed with behavioral and educational interventions or may require more support.
