The signs, symptoms, and effects of bipolar disorder can look different for each person impacted. Learning about bipolar disorder is one of the first steps toward healing.
Learn about bipolar disorder
Bipolar disorder is a severe mental disorder characterized by manic and depressive episodes. During a manic episode, a person may have excessive amounts of energy, a reduced need for sleep, may embark on large, unrealistic projects, and may engage in excessive risk-taking behaviors. During a depressive episode, a person may become withdrawn, have a depressed mood, lose pleasure in activities he or she used to enjoy, experience changes in weight, suffer from fatigue, and experience a decrease in his or her ability to problem-solve or concentrate.
While all bipolar disorders are diagnosed based on the presence of manic or hypomanic and depressive symptoms, there are three primary types of bipolar disorder: bipolar I, bipolar II, and cyclothymia. A person with bipolar I disorder experiences full manic and depressive episodes, while a person with bipolar II experiences hypomanic episodes and full depressive episodes. The mania of bipolar I and the hypomania of bipolar II are differentiated by the degree to which a person’s ability to function is impaired by the episode, with a hypomanic episode causing less overall impairment than a manic episode. Finally, cyclothymia is the least severe of the bipolar disorders. A person with cyclothymia experiences some symptoms of hypomania and some symptoms of depressive episodes but does not meet criteria for full hypomanic episodes or full depressive episodes.
Living with bipolar disorder can be extremely difficult, but thankfully, it is possible to receive treatment that can allow a person with bipolar disorder to manage his or her symptoms and live a full and happy life.
Bipolar disorder statistics
According to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, approximately 1.8 percent of people are struggling with bipolar disorder in a given year, and roughly the same number of men and women are diagnosed with the disorder. About 1 percent of people are diagnosed with cyclothymic disorder. Bipolar disorders also tend to be more common in more affluent countries.
Causes and risk factors for bipolar disorder
While the exact causes and risk factors for bipolar disorder continue to be researched, experts agree that the following factors play a role in determining a person’s risk of being diagnosed with bipolar disorder:
Genetic: A person’s genetics play a powerful role in determining his or her risk of developing bipolar disorder. People who have family members with bipolar disorder are nearly ten times more likely to be diagnosed with the disorder than are people without a family history of bipolar disorder. In addition, people with a family history of schizophrenia are also more likely to be diagnosed with bipolar disorder.
Environmental: Bipolar disorder tends to be more common in wealthier countries than in poorer countries. In addition, people who are separated, widowed, or divorced are also more likely to have the disorder.
- Family history of bipolar disorder or substance use disorder(s)
