Depressive disorder

Depressive disorders are disorders that are characterized by the presence of irrationally sad, empty, and irritable moods that cause a significant decrease in human function. They are not combined into a singular diagnosis because they differ in duration, timing, or presumed cause. According to international guidelines, a depressive disorder should not be diagnosed in anyone with a history of manic episodes because then their condition would fall under a bipolar disorder.
