title: [Sleep-wake disorders and DSM-5].
abstract: BACKGROUND
  Most individuals with mental disorders complain about the problems they experience with sleeping and waking. It is becoming evident that careful diagnosis of sleep-wake disorders is of great importance for the prevention and treatment of mental disorders. Since the introduction of the DSM-IV, clinical scientific research has provided important new insights in this field.
  
  
  OBJECTIVE
  To find out whether the new classification of sleep-wake disorders in DSM-5 is likely to improve the diagnosis of disorders of this type.
  
  
  METHODS
  We discuss the main changes in the DSM-5 classification of sleep- wake disorders, comparing the new version with the version in DSM-IV.
  
  
  RESULTS
  Because considerable attention is being given to the symptom-orientated and dimensional approach, the classification of sleep-wake disorders in the DSM-5 is closer to current psychiatric practice and it does justice to the current scientific insights into the dimensional nature of psychiatric disorders.
  
  
  CONCLUSIONS
  The DSM-5 classification takes recent scientific insights into account and might help to improve the diagnosis of sleep-wake disorders in psychiatry.
