Bipolar disorder, also known as manic depression, is a treatable illness involving extreme changes in mood, thought, energy, and behavior. A person with bipolar disorder has moods that usually alternate between mania, or extremely âupâ mood, and depression, or extremely âdownâ mood. This change or âmood swingâ can last for hours, days, weeks, or even months. Typically, someone with bipolar disorder experiences one or two cycles a year, with manic episodes generally occurring in the spring or fall.
