This is Science Today. After the Gulf War, most
American servicemen and women returned home safely.
But since then, thousands have complained of symptoms
ranging from memory loss to fatigue. So far, scientists
have been unable to figure out what causes the so-called
Gulf War Illness-or whether it even exists. Now,
Dr. Michael Weiner of the University of California,
San Francisco is looking to answer some of the big
questions about Gulf War Illness.
