Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. Symptoms of bipolar disorder are severe. They are different from the normal ups-and-downs that everyone goes through from time to time. Bipolar disorder symptoms can result in damaged relationships, poor job or school performance, and even suicide. But bipolar disorder can be treated. A combination of professional counseling and medication helps most people return to productive and fulfilling lives.

Bipolar symptoms may seem like separate problems, not recognized as parts of a larger problem, so it can be years before a person is properly diagnosed and treated. Bipolar disorder often develops in a person's late teens or early adult years, and it has been reported that at least half of all cases start before age 25. Some people have their first symptoms during childhood, while others may develop symptoms late in life. Like diabetes or heart disease, bipolar disorder is a long-term illness that must be carefully managed throughout a person's life.

Bipolar mood changes are called episodes, and people usually shift from manic to depressive episodes.
