Bipolar I Disorder
Defined by at least one manic episode lasting a week or requiring hospitalization, often followed by depressive periods.
Mania can involve psychosis or severe impairment. Treatment typically includes mood stabilizers to prevent extreme highs.
Bipolar II Disorder
Features hypomanic episodes (milder mania) alternating with major depression, without full manic phases. Hypomania may feel
productive but leads to crashes. Focus is on antidepressants and therapy to balance lows.
