atypical pervasive developmental disorder

ASD | autism spectrum disorder | pervasive developmental disorder | PDD [Abbr.]

Definition: A type of pervasive developmental disorder that differs from childhood autism either in age of onset or in failing to fulfil all three sets of diagnostic criteria. This subcategory should be used when there is abnormal and impaired development that is present only after age three years, and a lack of sufficient demonstrable abnormalities in one or two of the three areas of psychopathology required for the diagnosis of autism (namely, reciprocal social interactions, communication, and restricted, stereotyped, repetitive beh ...[+++]aviour) in spite of characteristic abnormalities in the other area(s). Atypical autism arises most often in profoundly retarded individuals and in individuals with a severe specific developmental disorder of receptive language. | Atypical childhood psychosis Mental retardation with autistic features

Definition: A disorder in which the main feature is a serious impairment in the development of motor coordination that is not solely explicable in terms of general intellectual retardation or of any specific congenital or acquired neurological disorder. Nevertheless, in most cases a careful clinical examination shows marked neurodevelopmental immaturities such as choreiform movements of unsupported limbs or mirror movements and other associated motor features, as well as signs of impaired fine and gross motor coordination. | Clumsy child syndrome Developmental:coordination disorder | dyspraxia

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 associate ...[+++]d encephalopathy but the diagnosis should be made on the behavioural features. | Dementia infantilis Disintegrative psychosis Heller's syndrome Symbiotic psychosis

According to the Fédération québécoise de l'autisme et des autres troubles envahissants du développement, PDD comprises five disorders: autism, childhood disintegrative disorder, Asperger syndrome, pervasive developmental disorder not otherwise specified, which includes atypical autism, and Rett syndrome.

The other four developmental disorders are: childhood disintegrative disorder, Rett syndrome, pervasive development disorder not otherwise specified or atypical autism, and Asperger's syndrome.

Dysphasia is a pervasive impairment affecting verbal communication which is characterized by a slow and atypical development of the power of comprehension and use of language.

13. Remarks that the "big killers" (e.g. cancer diseases, cardiovascular diseases) and the "big cripplers" (e.g. musculo-skeletal disorders and other work-related chronic diseases, health problems resulting from e.g. unhealthy diets, drug abuse, environmental degradation and reduced physical activity) could be considerably reduced by general intersectoral policies and individual preventive policies and improved measures to address those factors in people's working and living environment which cause disease; stresses, therefore, the importance of developing occupational health care with a view to the prevention and early detection of dis ...[+++]eases and health problems;
