A mood disorder is a psychological disorder in which a disturbance in mood (i.e., elevated mood, depressed mood, or a combination of both) is the main feature (DSM-5 2013). Currently, mood disorders are divided into two separate chapters: Depressive Disorders and Bipolar and Related Disorders (DSM-5 2013). Nine total diagnoses exist under Depressive Disorders including Disruptive Mood Dysregulation Disorder, Major Depressive Disorder, and Persistent Depressive Disorder (Dysthymia; see DSM-5 for complete list).
