Teen Disorders: Bipolar Disorder

Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in a person's mood, energy, and ability to function. More severe than the normal ups and downs that everyone goes through, the symptoms of bipolar disorder can be socially and emotionally debilitating. Untreated, bipolar disorder can lead to damaged relationships, poor job or school performance, and even suicide.
