title: [Sleep disorders and mental disorders].
abstract: BACKGROUND
  Recent research has revealed a lot of the secrets of sleep and how sleep influences our daily life and mental functioning.
  
  
  METHODS
  Current knowledge on the interaction between sleep disturbances and mental disorders is reviewed. The review is based on relevant literature identified by search in Medline and PsycInfo.
  
  
  RESULTS
  Research shows that sleep as a psychobiological phenomenon interacts with the processes of mental disorders. The best evidence for interactions between sleep disturbances and mental problems is found in depression, and sleep disturbances over some weeks have been found to be a predictor for depressive disorders.
  
  
  CONCLUSIONS
  Clinicians must distinguish between primary chronic sleep disorders of functional origin and secondary sleep disorders as part of a psychiatric condition. The former category should be treated by non-pharmacological interventions, while the latter should be adequately treated in a biopsychosocial model.
