Bipolar disorder, sometimes referred to as manic depression, is a mental disorder in which a person's emotions cycle gradually or rapidly between extreme states of being (generally mania or euphoria and depression). Different types of bipolar disorder are recognized based on the illness's presentation. These include Bipolar I, Bipolar II, and Mixed Bipolar. Each year, Bipolar disorder affects 2-3% of the U.S. population. There is no cure for Bipolar disorder, but it can generally be managed with psychotherapy and medication.
