Complications in Depression

Depression is often chronic, with episodes of recurrence and improvement. Approximately one-third of patients with a single episode of major depression will have another episode within 1 year after discontinuing treatment, and more than 50% will have a recurrence at some point in their lives. Depression is more likely to recur if the first episode was severe or prolonged, or if there have been recurrences. To date, even newer antidepressants have failed to achieve permanent remission in most patients with major depression, although the standard medications are very effective in treating and preventing acute episodes.

Risk for Suicide

About 90% of suicides are due to treatable disorders, most commonly depression or substance abuse. People with depression have up to a 15% risk for suicide, with the highest risk in patients who are hospitalized for depression. Some studies indicate that atypical depression poses a higher risk for suicide than typical depression and that dysthymia may pose a higher risk than episodic major depressive disorder. Depressed men are more likely to commit suicide than depressed women, and in the U.S. and around the world, suicide is most common in men older than 60. Suicidal preoccupation or threats of suicide should always be treated seriously in anyone, however.
