- Bipolar type 1 – Patients experience manic episodes and, in most cases, also experience major depressive and hypomanic episodes.
- Bipolar type 2 – Patients experience at least 1 hypomanic episode and at least 1 major depressive episode but do not have manic episodes.
The estimated prevalence of bipolar type 1 and bipolar type 2 disorders in the United States is 1.8%. The bipolar disorders have the highest genetic link of all major mental illnesses, with an up to tenfold increase in risk among individuals with relatives who have bipolar disorders. Symptoms usually begin in early adulthood, and bipolar disorder is less commonly diagnosed during childhood or adolescence. There is no difference between the sexes in prevalence of the disease. However, women are more likely to experience more depressive symptoms than men. There is an increased risk of substance use disorders and suicidal ideation or suicide attempt in individuals with bipolar disorder.
