Scientific Definition

Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) is a neurodevelopmental disorder that was previously a separate diagnosis but is now included under the umbrella of autism spectrum disorder (ASD). PDD-NOS is characterized by impairments in social interaction, communication, and restricted or repetitive behaviors that do not meet the full diagnostic criteria for other pervasive developmental disorders like autistic disorder or Asperger’s syndrome. It’s estimated that PDD-NOS affects about 15 per 10,000 children.
