The Tidal Wave of Illness Among Gulf War Vets

From the Veterans Administration website:

Gulf War Veterans' Illnesses

Approximately 697,000 men and women served in Operations Desert Shield and Desert Storm from August 1990 to June 1991 during the Gulf War. In the years since they returned, nearly a quarter of Gulf War veterans have experienced illnesses that have led VA and others to investigate whether exposures during deployment caused their symptoms.  The evidence remains unclear.

There are many links to research and documents about these illnesses at this VA page:
