Gulf War Syndrome

Gulf War syndrome, also called Gulf War illness or chronic multisymptom illness, cluster of illnesses in veterans of the Persian Gulf War (1990–91). Gulf War syndrome is characterized not by any definable medical condition or diagnostic test but by variable and nonspecific symptoms. While not fatal, it is associated with considerable distress and disability. In 2013 the Institute of Medicine (later renamed National Academy of Medicine), an American nongovernmental organization, estimated that about 200,000, or roughly one-third of Gulf War veterans, suffered from Gulf War syndrome.
