Gulf War Syndrome vets have notable brain abnormalities likely triggered by nerve gas, researchers have discovered. The finding flies in the face of years of Defense Department pronouncements that the syndrome—characterized by pain, lack of concentration and memory loss—is psychological, and linked to combat stress. But vets suffering from the syndrome show marked abnormalities in their brains that show up on MRIs, a University of Texas study has found. Damaged parts of the brain react differently to an injected neurotransmitter, reports the Dallas Observer.

Researchers believe the abnormalities were caused by exposure to small amounts of sarin gas—thought another study has indicated that drugs given to service members to protect against nerve gas may have also been toxic. "This was really one of the first techniques to show an objective picture of whether there's really brain damage or not," said the lead researcher in the current study. But theories now about how to treat the problem are a "shot in the dark," he added. The Veteran Administration estimates that a quarter of the 700,000 troops deployed to the 1991 Persian Gulf War suffer from the syndrome. (More Gulf War Syndrome stories.)
