The diagnosis of a mood disorder requires the presence or absence of a mood episode: major depressive episode, manic episode, or hypomanic episode. The mood disorders include major depressive disorder, persistent depressive disorder, bipolar I disorder, bipolar II disorder, and cyclothymic disorder. The mood disorders can be specified with seasonal pattern, rapid cycling, or peripartum onset.

Mood disorders are characterized predominantly by a disturbance in mood. Although earlier editions of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) grouped a wide variety of disorders under the heading of mood disorders, the fifth edition of the DSM (DSM-5), published in 2013, divides them into two categories: depressive disorders and bipolar and related disorders. Both categories include disorders characterized by mood episodes, which include major depressive episode, manic episode, and hypomanic episode.
