"A congressionally mandated scientific panel has concluded that Gulf War syndrome is real and still afflicts nearly a quarter of the 700,000 U.S. troops who served in the 1991 conflict, according to a report released Monday.
The report broke with most earlier studies by concluding that two chemical exposures were direct causes of the disorder: the drug pyridostigmine bromide, given to troops to protect against nerve gas, and pesticides that were widely used -- and often overused -- to protect against sand flies and other pests."
