Bipolar disorder, previously referred to as manic-depressive illness, is a disorder affecting mood, behavior, and cognition. Individuals with bipolar disorder experience symptoms from two “poles”: (1) depression, characterized by low mood, sadness, anhedonia, sleep and appetite disturbance, poor concentration, fatigue, feelings of guilt and worthlessness, and psychomotor slowing; and (2) mania, distinguished by euphoric, elevated and/or irritable mood, decreased need for sleep, increased energy and activity, hypersexuality, pressured speech, racing thoughts, grandiosity, and increased risk-taking.
