pervasive developmental disorder | PDD

pervasive developmental disorder not otherwise specified | PDD-NOS [Abbr.]

Definition: A type of pervasive developmental disorder that is defined by a period of entirely normal development before the onset of the disorder, followed by a definite loss of previously acquired skills in several areas of development over the course of a few months. Typically, this is accompanied by a general loss of interest in the environment, by stereotyped, repetitive motor mannerisms, and by autistic-like abnormalities in social interaction and communication. In some cases the disorder can be shown to be due to some associated encephalopathy but the diagnosis should be made on the behavioural features. | Dementia infantilis Disi ...[+++]ntegrative psychosis Heller's syndrome Symbiotic psychosis

Definition: A type of pervasive developmental disorder that is defined by: (a) the presence of abnormal or impaired development that is manifest before the age of three years, and (b) the characteristic type of abnormal functioning in all the three areas of psychopathology: reciprocal social interaction, communication, and restricted, stereotyped, repetitive behaviour. In addition to these specific diagnostic features, a range of other nonspecific problems are common, such as phobias, sleeping and eating disturbances, temper tantrums, ...[+++] and (self-directed) aggression. | Autistic disorder Infantile:autism | psychosis | Kanner's syndrome

Definition: A somewhat heterogeneous group of disorders that have in common abnormalities in social functioning which begin during the developmental period, but which (unlike the pervasive developmental disorders) are not primarily characterized by an apparently constitutional social incapacity or deficit that pervades all areas of functioning. In many instances, serious environmental distortions or privations probably play a crucial role in etiology.

The website of the Fédération québécoise de l'autisme et des autres troubles envahissants du développement says that autistic disorder, better known as autism or Kanner's autism, is one of five pervasive developmental disorders.

Other Pervasive Developmental Disorders, all of which share features of autism, include Rett's disorder, Asperger's syndrome, Childhood Disintegrative disorder, and PDD not otherwise specified (PDD-NOS).
