Specific developmental disorders are disorders in which development is delayed in one specific area or areas,[1] and in which basically all other areas of development are not affected.[2] Specific developmental disorders are as opposed to pervasive developmental disorders[2] that are characterized by delays in the development of multiple basic functions including socialization and communication.

ICD-10 taxonomy

The tenth revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) has four categories of specific developmental disorder: specific developmental disorders of speech and language, specific developmental disorders of scholastic skills, specific developmental disorder of motor function, and mixed specific developmental disorder.

DSM-IV taxonomy

In the Diagnostic and Statistical Manual of Mental Disorders DSM, SDD was opposed to the pervasive developmental disorders (PDD). There were two factors that were considered:

  • The specificity of the impairment: in SDD there is one single domain that is affected, whereas in PDD multiple areas of functioning are affected.[3]
  • The nature of the impairment: development in SDD is delayed but not otherwise abnormal, whereas in PDD there are behavioral deviations that are not typical for any developmental stage.[3]

In the DSM-IV-TR specific developmental disorders are no longer grouped together. Instead they are reclassified as communication disorders, learning disorders, and motor skills disorders.[citation needed]
