Pervasive developmental disorder (PPD) is a group of five developmental children's diseases that present as delays in socialization and communication skills. Children with PPD have problems talking, playing with others and expressing how they feel. The five diseases are: autism, Rett syndrome, childhood disintegrative disorder, Asperger syndrome and pervasive developmental disorder not otherwise specified.NICHCY: Pervasive Developmental Disorders

Pervasive developmental disorder not otherwise specified is characterized by the standard PDD symptoms, difficulty with interaction, communication and play, yet the symptoms are not severe enough or they do not match the symptoms of the other pervasive developmental disorders.NICHCY: Pervasive Developmental Disorders
