Gulf War Syndrome is a medical condition that was initially expressly equated with the first Gulf War, although certain symptoms have been found to span other conflicts in the Middle East and surrounding areas since then. The U.S. soldiers returning from the first Gulf War began suffering from chronic health issues that were chronicled and eventually became categorized as Gulf War Syndrome. More than 650,000 Service members served in Operation Desert Shield and Desert Storm from August 2, 1990 to July 31, 1991. For VA benefits eligibility purposes, the Gulf War period is still in effect. This means that anyone who served on active duty from August 2, 1990, to present is considered a Gulf War Veteran.
