In the Sept. 23 Neurology, the researchers report that soldiers deployed to the gulf were 1.92 times more likely to develop ALS in the decade following the conflict than if they had not been deployed.
In a second study in the same journal, Robert W. Haley of the University of Texas Southwestern Medical Center in Dallas tracked down 17 veterans who were diagnosed w
