Bipolar Disorder

According to the World Health Organization, bipolar disorder is the sixth leading cause of disability in the world. The condition affects approximately 5.7 million adult Americans—about 2.6 percent of the U.S. population age 18 and older.

There are three types of bipolar disorder:

  • Bipolar I Disorder (mania or a mixed episode):The classic manic-depressive form of the illness, characterized by at least one manic episode or mixed episode. Bipolar I Disorder also involves at least one episode of depression.
  • Bipolar II Disorder (hypomania and depression):In Bipolar II disorder, the person doesn’t experience full-blown manic episodes. Instead, the illness involves episodes of hypomania and severe depression.
  • Cyclothymia (hypomania and mild depression):Cyclothymia is a milder form of bipolar disorder. It also consists of cyclical mood swings, but the symptoms are less severe than full-blown mania or depression
