title: [The concept of «multiple complex developmental disorder» - a disorder of social interaction, paranoid thinking and social anxiety in a 17-year-old boy].
abstract: OBJECTIVE
  Multiple complex developmental disorder (MCDD) is a little-known disorder characterized by disturbances in the regulation of emotions, social interactions and thought disorders. Neither the classification system of ICD-10 nor the DSM-IV lists MCDD as an independent disorder.
  
  
  METHODS
  The study presents an overview on diagnostic criteria, current research and illustration by a case report of a 17-year-old adolescent.
  
  
  RESULTS
  MCDD, autistic disorders and schizophrenic disorders partially overlap. A clear classification or differentiation is currently not clearly possible.
  
  
  CONCLUSIONS
  Many open questions remain, and further research is needed.
