The Gulf War Syndromes UT Southwestern researchers studied 249 members of a U.S. Navy reserve unit and found that up to one-fourth of them suffered symptoms that occur togetherm indicating a possible syndrome.
Chronic diarrhea is common in all three syndromes.
None of the 249 veterans was near Khamisiyah at any time in the war. Psychological testing showed that none is suffering from stress. Veterans with syndrome 2 were more likely to be unemployed. A definition of the Gulf War syndrome developed for the U.S. Department of Defense from examinations of Gulf War veterans who remained on active duty in 1994 closely mirrored syndromes 1 and 3 but did not reflect syndrome 2.
