Pervasive Developmental Disorder (PDD)

What is a Pervasive Developmental Disorder (PDD)?

There are many childhood disorders under the PDD umbrella. The most widely known PDD is Autism. Professionals and parents of children with PDD often describe individuals as being "on the spectrum" meaning that their behaviors fall on a continuum regarding the intensity of observed symptoms.

Individuals with PDD display significant deficits in three major areas: (1) social interaction, (2) communication, and (3) stereotyped and/or repetitive patterns of behavior and interests (i.e., hand flapping, lining up objects, inflexible adherence to nonfunctional routines, and preoccupation with parts of objects).
