Pervasive Developmental Disorders

Six Specific Disorders

Autistic Disorder (see section regarding Autism)

Rett’s Disorder

Also – Rett’s Syndrome – disgnosed primarily in girls. Development proceeds normally until 6-18 months of age when behavior and abilities regress. Gross motor skills also regress. Then, speech, reasoning and hand use are lost. Repetition of some gestures and movements begin (constant hand-wringing or hand washing).

Childhood Disintegrative Disorder

A rare disorder – classified by regression in ability to move, bladder and bowel control, and social and language skills. These appear after a period of at least two years of relatively normal development. The onset is prior to age 10.

Asperger’s Disorder (see section regarding Aspergers Disorder)


These students do not meet the criteria for the other four PDD diagnoses or do not meet the degree of impairment of the other four diagnoses. The DSM IV states this diagnosis be applied “when there is a severe and pervasive impairment in the development of social interaction or verbal and nonverbal communication skills, or when stereotyped behavior, interests, and activities are present, but the criteria are not met for a specific PDD.”
