How to Diagnose Major Depressive Disorder

If you feel sad, lethargic and dejected about your life, you may be experiencing a major depressive episode. Approximately one in six adults experiences a depressive episode at some time in her life, making depression one of the most common mental health problems. Mental health professionals use the Diagnostic and Statistical Manual of Mental Disorders, or DSM-IV, to diagnose major depressive disorder. Although only a licensed psychiatrist or clinical psychologist can formally diagnose major depression, recognizing the primary symptoms allows you to seek treatment for your mental health problems.
