Corticosteroid-induced psychotic and mood disorders: diagnosis defined by DSM-IV and clinical pictures.

The authors investigated long-term outcome and treatment strategy of corticosteroid-induced psychotic and mood disorders as defined by DSM-IV. Review of medical records of 2,069 referral patients revealed 18 applicable patients. Their clinical characteristics, longitudinal courses, and treatments were studied. The authors identified 15 patients with mood disorder and 3 patients with psychotic disorder. Increasing doses or resumption of corticosteroids had the strongest influence on the psychiatric course. These two corticosteroid-induced psychiatric disorders may have different pathophysiological substrates closely related to patient vulnerability. Effective psychopharmacological treatment options were indicated with consideration being given to the underlying diseases.
