Despite the clinician's goal of treating the depressed patient to the point of remission, this state is generally achieved in only 15% to 30% of patients. Another 10% to 30% of patients respond poorly to antidepressant treatment, while 30% to 40% have a remitting and relapsing course.1 Patients without a major depressive disorder are likely to be treated successfully by primary care physicians and/or other mental health professionals, which leaves psychiatrists to treat patients who have forms of depression that are less responsive to treatment.
