The Board granted service connection for multiple chemical sensitivity syndrome (MCSS), chronic fatigue syndrome (CFS) secondary to MCSS, and an acquired psychiatric disorder, to include depression and panic disorder, secondary to MCSS.
The deciding factor: The evidence supports a nexus between the Veteran's in-service asbestos exposure and his current diagnosis of MCSS. The Board finds that the record is at least in approximate balance as to whether the Veteran's MCSS is due to in-service exposure to asbestos, resolving all reasonable doubt in the Veteran's favor.
