[A Systematic Review of Personality Disorders and Addiction: Epidemiology, Course and Treatment].

Aim: This paper provides a systematic overview of the comorbidity of personality and addictive disorders including behavioural addictions.

Method: Systematic review.

Results: Personality disorders and substance-related addictions show high comorbidity rates. This is equally true of behavioural addictions. Most empirical research is on comorbidity with borderline personality disorder. For treatment of individuals with dual diagnoses, three psychotherapies have been demonstrated to be effective. Pharmacotherapeutic approaches have hardly been investigated.

Conclusion: METHODologically integrative treatment represents therapy of choice for patients with dual diagnoses. Comorbidity of personality disorders and behavioural addictions needs further investigation.
