Bipolar Disorder

A condition marked by extreme shifts in mood, energy, and activity levels.

What is Bipolar Disorder?

Bipolar disorder is a brain disorder that causes unusual shifts in mood, energy, activity levels, concentration, and the ability to carry out day-to-day tasks. These mood episodes range from very "up," elated, irritable, or energized periods (called manic or hypomanic episodes) to very "down," sad, or hopeless periods (called depressive episodes).

Bipolar disorder affects approximately 2.8% of adults in the United States, about 7 million people. Symptoms often appear during late adolescence or early adulthood, although they can occur at any age.

Bipolar disorder is a lifelong condition, but with the right treatment and support, people can live full and productive lives.

Types of Bipolar Disorder

Bipolar I Disorder

Defined by manic episodes that last at least seven days, or by manic symptoms so severe that immediate hospital care is needed. Depressive episodes typically occur as well, lasting at least two weeks.

Bipolar II Disorder

Defined by a pattern of depressive episodes and hypomanic episodes (less severe than full mania). People with Bipolar II do not experience full-blown manic episodes.

Cyclothymic Disorder

Periods of hypomanic and depressive symptoms that last for at least two years but do not meet the full criteria for hypomanic or depressive episodes.
