Bipоlаr disоrder is а chrоnic mood disorder chаracterized by the presence of mania (bipolar I disorder) or hypomania and depression (bipolar II disorder). Manic episodes are distinct periods of abnormally and persistent moods that can be euphoric, expansive, or irritable. Manic patients often have greatly inflated self-esteem, confidence, decreased need for sleep, pressured speech, racing or crowded thoughts, distractibility, increased involvement in goal-directed activities (e.g., starting many projects but being unable to finish any), hypersexuality, and excessive involvement in pleasurable activities with a high potential for painful consequences. Despite mania being the defining characteristic of the disease, depressed moods tend to predominate, with bipolar I patients experiencing a 3:1 ratio of depression to mania over the course of the illness. Hypomania consists of manic episodes that do not lead to social or occupational dysfunction. Pharmacologic treatment for bipolar consists of mood stabilizers such as lithium, valproic acid, and carbamazepine. Lithium is typically considered the first-line maintenance medication for bipolar disorder. Bipolar disorder is associated with a high rate of suicide (up to 15%) and several comorbidities such as substance abuse and anxiety disorders.
