What is a Pervasive Developmental Disorder (PDD)?
Pervasive Developmental Disorders refer to a broader group of neurobiological conditions, known as autistic spectrum disorders, that are characterized by delayed development of communication and social skills. Children with these disorders often have trouble relating and communicating with others, and have noticeable difficulty in using and understanding language. They may also exhibit unusual play with toys and other objects, including flicking or shaking toys in nontraditional manners, repetitively spinning toys, and lining up toys instead of playing with them. These children often have extreme difficulty with changes in routine.
