Quizplus · Accepted Answer

Dysthymia, also known as persistent depressive disorder, is characterized by chronic low mood and other symptoms of depression that persist for at least two years (or one year for children and adolescents). Dysthymia has been debated as a potential personality disorder due to its persistent nature and the belief that it may be indicative of an individual's underlying personality traits. However, it is currently classified as a mood disorder in the DSM-5.
