Overview
Bipolar disorder is a serious mental illness characterized by extreme swings in mood. Patients alternate between manic (extremely high energy, euphoria) and depressive periods. Lifetime prevalence is 2-3%.
Formerly known as "manic-depressive illness," this condition can be largely controlled with proper treatment. Untreated cases carry a high risk of suicide.
