Quick Answer
Bipolar I requires at least one full manic episode — a period of significantly elevated, expansive, or irritable mood plus increased energy and activity, lasting at least 7 days or requiring hospitalization. Bipolar II involves hypomanic episodes (less severe than full mania, lasting at least 4 days) plus major depressive episodes. Bipolar II is often missed because hypomania can feel pleasant or productive — patients usually only seek help during the depressive episodes. Both types share the same treatment foundation: mood stabilization first, careful use of antidepressants only with a mood stabilizer on board.
