Generalized Anxiety Disorder is rated by the U.S. Department of Veterans Affairs under DC 9400 of 38 CFR § 4.130, DC 9400 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. This condition is frequently rated as secondary to Sleep Apnea or GERD under 38 C.F.R. § 3.310.
Generalized Anxiety Disorder (GAD) is characterized by excessive, hard-to-control worry occurring more days than not for at least six months, spanning multiple domains such as health, finances, work, and safety. Under DSM-5 the worry pairs with at least three of six physical and cognitive symptoms (restlessness or feeling keyed up, easy fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbance), and the disturbance causes clinically significant distress or impairment not better explained by another mental disorder. GAD frequently co-occurs with depression and other anxiety conditions, which is why VA evaluates the overall functional picture rather than the label alone.
