Mania requires symptoms for at least how long?

• A. 3 days
• B. 1 week
• C. 2 weeks
• D. 1 month

Answer: (B)

Mania is defined by a distinct period of abnormally elevated, expansive, or irritable mood with increased energy or activity that lasts at least one week (or any duration if hospitalization is necessary). That one-week threshold establishes a sustained pattern of mood and behavior change with impairment in functioning. If the person is hospitalized because of severe symptoms, the duration can be shorter and yet still meet the criterion. Compared to mania, hypomania requires at least four days but does not involve the same level of impairment or need for hospitalization. Therefore, the minimal duration for mania is one week, while longer periods also fit as long as the mood disturbance and impairment are present.
