Mania - Course

Course

Manic episodes can last from a few weeks to two to three months in length, and they are often preceded by stressful life events. While the average age for a first manic episode is in the early twenties, some occur in the teenage years. Those who have their first episode in their teens often have a history of behavior problems. Sometimes mania is not seen until after age 50.

Over 90% of individuals who have one manic episode will have additional episodes. And approximately 60-70% of manic episodes occur just before or after periods of major depression. While this may paint a rather bleak picture, it should be noted that some experts hold that while up to 40% of those with bipolar disorder will experience repeating cycles, they rarely experience long-term physical or mental impairment. And most people with bipolar disorder have periods with almost no symptoms in which they essentially function normally.
