Autistic spectrum disorders--including autism, pervasive developmental disorders not otherwise specified (PDD-NOS), Asperger's syndrome, and others--are labels to describe neurological conditions that can affect a person's speech and communication, emotional growth, social skills, and physical and mental abilities.
