Pervasive Developmental Disorder. A broad category of disability that involves problems in social interaction and verbal and nonverbal communication. PDD is not a specific diagnosis but an umbrella term for several disorders and syndromes considered to be mental and/or behavioral disorders. Its major diagnosis is autism. PDD not otherwise specified (PDDNOS) refers to children who have autistic characteristics but do not formally qualify for the diagnosis.
