Bipolar disorder is a mental health condition defined by periods (or episodes) of extreme mood disturbances that affect mood, thoughts, and behavior. There are two main types of bipolar disorders. Bipolar I disorder involves episodes of severe mania and often depression. Bipolar II disorder involves a less severe form of mania called hypomania.1 There is also a third type known as cyclothymic disorder.
Estimates suggest that around 4.4% of U.S. adults will have bipolar disorder at some point in their lives.2 Genetics are thought to play a significant role, although brain abnormalities and environmental factors also contribute as causes of bipolar disorder. Mood stabilizers are usually the first-line treatment, but electroconvulsive therapy (ECT) may be used to address severe symptoms.
