Personality Disorder (Service-Connected Aggravation) is rated by the U.S. Department of Veterans Affairs under DC 9440 of 38 CFR § 4.130, DC 9440; VAOPGCPREC 82-90 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.
A personality disorder is an enduring, pervasive pattern of inner experience and behavior - involving cognition, affect, interpersonal functioning, or impulse control - that deviates markedly from cultural expectation, is inflexible across situations, and traces to adolescence or early adulthood per DSM-5 (clusters include borderline, antisocial, schizotypal, avoidant, and others). Because the pattern is developmental in origin, VA treats a personality disorder as a congenital or developmental defect that is generally not a compensable disease or injury under 38 CFR 3.303(c), so direct service connection on its own is barred. The compensable theory here is superimposed aggravation: a personality disorder that pre-existed service and was permanently worsened beyond its natural progression by an in-service event, or an acquired mental disorder (such as PTSD or depression) that became superimposed on the underlying personality pathology during service.
