Autism is a complex neurobehavioral condition that includes impairments in social interaction and developmental language and communication skills combined with rigid, repetitive behaviors. Because of the range of symptoms, this condition is now called Autism Spectrum Disorder (ASD). Children with autism have trouble communicating.
