Bipolar II disorder (pronounced bipolar two) is a form of mental illness. Bipolar II is similar to bipolar I disorder, with moods cycling between high and low over time. However, in bipolar II disorder, the up moods never reach full-on mania. The less-intense elevated moods in bipolar II disorder are called hypomanic episodes, or hypomania.
Bipolar disorder, also known as manic depression, is a mental illness that brings severe high and low moods and changes in sleep, energy, thinking, and behavior. People who have bipolar disorder can have periods in which they feel overly happy and energized and other periods of feeling very sad, hopeless, and sluggish. In between those periods, they usually feel normal. You can think of the highs and the lows as two poles of mood, which is why it's called bipolar disorder.
