Bipolar I Disorder requires at least one manic episode lasting how long?

• A. 7 days or more
• B. 4 days
• C. 1 day
• D. 2 weeks

Answer: (A)

Manic episodes have a specific time requirement to be considered clinically significant. For a manic episode, the period of abnormally elevated or irritable mood with increased energy must last at least seven days, unless hospitalization is needed to prevent harm, in which case the episode can be shorter but still counts as manic. This duration threshold distinguishes mania from hypomania, which lasts at least four days but does not cause marked impairment or require hospitalization. Bipolar I Disorder is diagnosed after at least one manic episode, making seven days (or shorter if there’s hospitalization) the minimum duration. Shorter spans like four days (hypomania), one day, or a longer but not the minimum duration do not meet the manic criterion.
