Illness A group of scientists has determined that former service members who suffer from Gulf War Illness – which they sustained during Operation Desert Storm in 1990 and 1991 – are experiencing a host of maladies directly related to their condition. The scientists were funded in part by the Defense Department’s Congressionally Directed Medical Research Program and the Army’s medical research and material command. Their report appeared June 14 on the Web site of PLOS, www.plos.org, a non-profit organization of scientists and physicians that publishes peer-reviewed medical and scientific literature free of charge. The researchers studied 28 Gulf War veterans and 10 other unaffected subjects, focusing on the effects of exercise. They determined that one group of subjects experienced lightheadedness, palpitations, and "a subsequent loss of compensation after exercise," according to the scientists’ report. Another group reported increased sensitivity to pain.
