Depersonalization/Derealization Disorder is rated by the U.S. Department of Veterans Affairs under DC 9417 of 38 CFR § 4.130, DC 9417 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.
Depersonalization/Derealization Disorder is a dissociative condition marked by persistent or recurrent episodes of feeling detached from, or like an outside observer of, the own mind, body, or actions (depersonalization), and/or experiencing the surrounding world as unreal, dreamlike, foggy, or visually distorted (derealization). A defining DSM-5 feature is that reality testing stays intact during episodes, so the person knows the experience is a perceptual disturbance and not a delusion or psychotic break. The detachment is chronic and distressing, frequently described as emotional numbing or "going through the motions," and commonly co-occurs with trauma exposure, anxiety, and depression.
