Bipolar Disorder

Bipolar disorder causes extreme mood swings, from very high energy (mania) to depression. Your mood may return to normal between these swings. Bipolar disorder is also called manic-depressive disorder. It often begins in the teen or early adult years, and it may run in families.

This illness can cause behavior so extreme that it's hard to work or have successful relationships. Medicines and counseling may help control the symptoms.
