Bipolar Disorder

Bipolar disorder is a mental disorder that causes unusual shifts in mood, energy, activity levels, concentration, and the ability to carry out day-to-day tasks. Bipolar disorder is typically diagnosed during late adolescence (teen years) or early adulthood. If you think you or a loved one has bipolar disorder, talking with a doctor or other licensed health care provider is the first step. Know the signs and symptoms.
