The diagnosis of bipolar disorder type I (BPI) requires the presence of a manic episode of at least 1 week’s duration or that leads to hospitalization or other significant impairment in occupational or social functioning. The episode of mania cannot be caused by another medical illness or by substance abuse. These criteria are based on the specifications of the DSM-5. [2] The Department of Veterans Affairs and Department of Defense (VA/DOD) recommend using a standardized rating scale such as the Young Mania Rating Scale to assess the severity of a manic episode.
