A 26-year-old female presents after a 4-day episode of increased energy, decreased need for sleep (5 hours, feeling rested), rapid speech, and increased productivity at work. She felt "amazing" during the episode but did not miss work, was not hospitalized, and did not experience psychotic features. She has a history of two major depressive episodes. The episode resolved on its own. What is the MOST likely diagnosis?
Explanation
Bipolar II requires at least one hypomanic episode and at least one major depressive episode, with no history of full mania. The 4-day duration with decreased sleep need, rapid speech, and increased energy meets hypomania criteria. The absence of hospitalization, psychosis, and marked functional impairment distinguishes hypomania from mania.
Key Takeaway
Bipolar II = ≥1 hypomanic episode (≥4 days) + ≥1 major depressive episode + never a full manic episode. Hypomania does not require hospitalization or psychosis and does not cause marked functional impairment.
