Pervasive developmental disorder

The pervasive developmental disorders are, in contrast to the circumscribed or specific developmental disorders, characterized by an impairment in communication and social relations as well as by a limited repertoire of activities. These disorders are congenital or acquired in early age, and the first symptoms show up before the age of three. The development is in accordance with the age at any time.

The two internationally used classification systems for diseases categorize the pervasive developmental disorders as follows:

The Diagnostic and Statistical Manual of Mental Disorders (DSM -IV) of 1994 identifies five pervasive developmental disorders:

  • 299.00: Autistic Disorder
  • 299.10: disintegrative disorder in childhood
  • 299.80: Rett Syndrome
  • 299.80: Asperger's Syndrome
  • 299.80: unspecified pervasive developmental disorder

In the International Statistical Classification of Diseases and Related Health Problems (ICD -10) of 1992 divided the pervasive developmental disorders into eight categories:

  • F84.0: infantile autism - ( Kanner's autism, Kanner 's syndrome)
  • F84.1: atypical autism
  • F84.2: Rett Syndrome
  • F84.3: Other disintegrative disorder of childhood - (eg Hellersche dementia)
  • F84.4: Overactive disorder with mental retardation and stereotyped movements
  • F84.5: Asperger Syndrome - ( formerly known as " autistic psychopathy ") is
  • F84.8: Other pervasive developmental disorder
  • F84.9: unspecified pervasive developmental disorder

All pervasive developmental disorders have some symptoms in common:

  • Difficulties with using and understanding language
  • Difficulties in relating to other people
  • Difficulty with changes in the environment and the daily routine
  • Repetitive body movements and other stereotypical behaviors
