Which of the following describes Dysthymic Disorder?

Dysthymic Disorder, now referred to as Persistent Depressive Disorder (PDD) in the DSM-5, is characterized by a chronic, low-grade depression lasting for at least two years in adults (one year in children and adolescents). This long-term depressive condition leads individuals to experience a persistent feeling of sadness or a loss of interest in normal activities, and while it may not be as severe as major depressive disorder, its duration makes it significant.

People with dysthymic disorder often find it challenging to function in daily life due to these ongoing symptoms, which can lead to a greater risk of developing major depressive episodes later on. Thus, the essence of this disorder lies in its chronic nature and its impact on one’s overall quality of life over an extended period, distinguishing it clearly from more transient depressive states, psychotic disorders, or anxiety disorders.
