• A. Bipolar II
• B. Bipolar I
• C. Cyclothymic Disorder
• D. Major Depressive Disorder

Answer: (A)

The pattern of hypomanic episodes paired with depressive episodes defines Bipolar II disorder. In Bipolar II, a person experiences at least one hypomanic episode—an elevated or irritable mood with increased energy lasting at least four days, noticeable to others but not causing severe impairment or psychotic symptoms—and at least one major depressive episode, which involves a distinct period of depressed mood or loss of interest lasting at least two weeks with additional symptoms like sleep changes, appetite/weight changes, fatigue, feelings of worthlessness, or thoughts of death. This combination distinguishes it from Bipolar I, which requires a full manic episode (more intense and often impairing or hospitalizable); from cyclothymic disorder, where mood fluctuations are milder and do not meet full criteria for hypomanic or major depressive episodes for a prolonged period; and from Major Depressive Disorder, which involves depressive episodes without a history of hypomanic or manic episodes.
