Persistent Depressive Disorder (Dysthymia) is rated by the U.S. Department of Veterans Affairs under DC 9433 of 38 CFR § 4.130, DC 9433 across 6 severity tiers (0% / 10% / 30% / 50% / 70%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Persistent Depressive Disorder (formerly dysthymia) is a chronic depressed mood lasting most of the day, more days than not, for at least two years (one year in adolescents), accompanied by at least two of the following: poor appetite or overeating, insomnia or hypersomnia, low energy, low self-esteem, poor concentration or difficulty making decisions, and feelings of hopelessness. Unlike a discrete major depressive episode, the defining feature is duration and persistence, with symptoms rarely absent for more than two months at a time, producing a grinding low-grade impairment that veterans often describe as just feeling down for years. DSM-5 allows a co-occurring major depressive episode to be layered on this baseline (the "double depression" pattern), which can intensify the disability picture.
