Bipolar I disorder is characterized by periods of deep, prolonged, and profound depression that alternate with periods of an excessively elevated or irritable mood known as mania. It is a common, severe, and persistent mental illness that is often a serious lifelong struggle and challenge. Patients who present with mania, hypomania, or depression should be evaluated for bipolar disorder. Between the extremes of "pure" mania and "pure" depression, patients can experience mixed states, in which various manic and depressive symptoms are present at the same time.

The lifetime prevalence of bipolar I disorder for the general population is nearly 1%. However, the prevalence is much higher among first-degree relatives of individuals with bipolar or schizophrenia disorder. The average age at onset is about 18-20 years, but it can occur in the teens or, more uncommonly, in childhood. The condition affects men and women equally.
