Summary

This lesson introduces dysthymia, its persistent pattern of depressive symptoms, and the core features clinicians consider during diagnosis.

Dysthymia is a chronic depressive condition marked by symptoms similar to those of major depressive disorder (MDD), but with a long-lasting course. The DSM-5-TR uses the name persistent depressive disorder (PDD), while ICD-11 uses dysthymic disorder. The DSM-5 adopted PDD in 2013, combining the former categories of dysthymic disorder and chronic major depressive disorder because evidence did not establish a clinically meaningful distinction between them.
