The main difference between bipolar I and bipolar II disorders pertains to severity of the high-energy episodes caused by each type. A person with bipolar I disorder will experience a full manic episode, whereas a person with bipolar II disorder will experience only a hypomanic episode (a period that is less severe than a full manic episode). Mania in bipolar I disorder often results in work, school, and relationship problems. In some cases, it may require hospitalization. A manic episode is also just as frequently characterized by an irritable mood as an elevated one for people with bipolar I disorder. The incidence of episodes has been found to be greater in patients with bipolar II disorder than in those with bipolar I disorder, although rates of hospitalization and presence of psychotic symptoms are significantly lower for patients with bipolar II disorder.
