Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pervasive Developmental Disorders (PDD) is a diagnostic category that includes five disorders related to developmental delays in basic functions including socialization and communication. Symptoms of PDD may be obvious as early as infancy or at the typical onset before three years of age. PDD includes the autism spectrum disorders (ASD) of autism and Asperger syndrome, as well as the more rare Rett Syndrome and childhood disintegrative disorder (CDD). This book explores each of the five disorders within PDD, the characteristics, causes, and treatments.
