How do symptoms of bipolar I disorder last?

ANSWER

If left untreated, an episode of mania can last anywhere from a few days to several months. Most commonly, symptoms continue for a few weeks to a few months. Depression may follow shortly after, or not appear for weeks or months.

Many people with bipolar I disorder have long periods without symptoms in between episodes. A few have rapid-cycling symptoms of mania and depression, in which they may have periods of mania or depression four or more times within a year.
