Abstract
The past decade has witnessed significant advances in the treatment of chronic depression. Several antidepressant medications1 and forms of psychotherapy2,3 have shown efficacy. Still, approximately 50% of chronically depressed patients in intent-to-treat analyses fail to respond to an adequate trial of antidepressant medication or psychotherapy, and an additional 20% do not obtain complete remission.1,4-6 This is important because residual symptoms are associated with significant functional impairment7 and increased risks of relapse and recurrence.8-10
