Depression and internal medicine.

Although the Fathers of Internal Medicine described melancholia and wrote extensively about the affective disorders, internists continue to have difficulties diagnosing their medical patients' depressions. Consequently, it often falls to the psychiatric consultant to make the diagnosis amongst the medical population. We present current concepts of affective disorder that should be clinically relevant to the psychiatrist who works with internists and their patients. Early, accurate diagnosis of depressed medical patients requires increased awareness of depression, observation of the patient's appearance and mood, sensitivity to his or her feelings, and specific questioning about symptoms, losses, and stressors. For depressed medical patients, we present a comprehensive treatment program which often should include: 1) supportive psychotherapy, 2) antidepressant medications; and 3) resocialization or rehabilitation. We outline certain indications for psychiatric referral, and urge psychiatrists and internists to work together closely. Increasing the sensitivity of our colleagues in internal medicine toward affective illness should lead to more prompt identification and treatment of medical patients' depressions.
