Chronic pain and the psychiatrist

SUMMARY Chronic pain is a phenomenon with important psychiatric aspects from a diagnostic as well as a therapeutic point of view. The place of chronic pain in the different versions of the Diagnostic and Statistical Manual of Mental Disorders, and the differential-diagnosis are critically discussed. The comorbidity with depression, anxiety disorders, substance abuse and personality disorders is extensively treated. Finally, the essential role of the psychiatrist in the multidisciplinary therapeutic approach of these patients is emphasised.
