Question

Quizplus · Accepted Answer

Bipolar I disorder is characterized by at least one manic episode, with or without major depressive episodes. Psychotic symptoms are not a requirement for diagnosis, although they can occur during severe manic or depressive episodes. Bipolar II disorder involves at least one hypomanic episode and one major depressive episode, but does not include the full-blown manic episodes seen in Bipolar I. Therefore, the presence or absence of psychotic symptoms is not a distinguishing factor for a Bipolar I diagnosis.
