Gulf War Syndrome
Many Gulf War veterans suffer from illnesses which the medically community does not clearly understand. Physicians sometimes refer to these poorly-known illnesses as undiagnosed illness, chronic fatigue syndrome or chronic multi-symptom illness. The causes of Gulf War syndrome are not well-known, but there is speculation that toxic exposure or medical vaccinations may be a cause.
At any rate, to qualify for VA benefits, a Gulf War veteran must have an undiagnosed illness, a medically unexplained chronic multi-symptom illness or one of the diagnosed illnesses listed in the regulations. Also, the illness must manifest a disability to a degree of ten (10) percent or more. See 38 U.S.C. § 1117.
