The Board found that the Veteran's Chiari malformation is a congenital defect and was not aggravated during active military service, thus denying his claim for service connection.
The deciding factor: Service connection requires evidence of a current disability. The Veteran's Chiari malformation was present since birth and considered congenital in nature. There was no evidence of additional disability due to a superimposed injury or disease during service.
