What Are the Types of Mood Disorders?

Major depression is the most common mood disorder. This debilitating illness causes mental anguish and physical ailments. It often prevents normal daily function. While some people with depression may experience only one episode of major depression in a lifetime, most endure multiple episodes.

Bipolar disorder, also called manic-depressive illness, is less common. Even so, it affects about 5.7 million American adults. Bipolar disorder is a combination of extreme elation, which is known as mania, and depression.
