Who gets mixed bipolar episodes?

ANSWER

Virtually anyone can develop bipolar disorder. About 2.5% of the U.S. population -- nearly 6 million people -- has some form of bipolar disorder.

Mixed episodes are common in people with bipolar disorder -- half or more of them have at least some mania symptoms during a full episode of depression. Those who develop bipolar disorder at a younger age, particularly in adolescence, may be more likely to have mixed episodes. People who develop episodes with mixed features may also develop "pure" depressed or "pure" manic or hypomanic phases of bipolar illness. People who have episodes of major depression but not full episodes of mania or hypomania also can sometimes have low-grade mania symptoms. These are symptoms that are not severe or extensive enough to be classified as bipolar disorder. This is referred to as an episode of "mixed depression" or a unipolar (major) depressive episode with mixed features.

Most people are in their teens or early 20s when symptoms from bipolar disorder first start. It is rare for bipolar disorder to develop for the first time after age 50. People who have an immediate family member with bipolar are at higher risk.
