The Veterans Affairs Department of united states announced that it will re-examine the disability claims of thousands of Persian Gulf War veterans still suffering from the mysterious Gulf War illnesses two decades after the war ended. At a meeting of the Federal Advisory Committee on Gulf War Veteran's Illnesses held yesterday in Washington, D.C., scientists from around the country presented their latest research to committee members searching for clues to this mysterious illness. Early in the meeting a new culprit emerged -- "the other brain" -- the non-electric portion of the brain composed of brain cells called glia.

Gulf War syndrome is characterized by a collection of unexplained symptoms, many of them neurological, including chronic pain, chronic fatigue, depression, sleep disturbances, memory loss, as well as gastrointestinal and lung problems. A number of causes have been suspected, including exposure to low-level neurotoxins, including sarin gas, drugs taken to protect soldiers from biological and chemical warfare agents, pesticides used to treat tents and soldier's uniforms stationed in the desert, depleted uranium from munitions, and the toxic mixture of fumes released for a year after the war ended from oil fields set ablaze by the retreating Iraq soldiers. The toxic fumes blotted out the sun at midday for miles.

Many people suffer chronic pain after an injury. Unlike normal pain, chronic pain does not end after the injury heals; in fact it often gets worse. The latest research shows that chronic pain results from an interaction between the immune system and the brain. When we are sick, substances are released by the body that tell the brain to initiate the familiar "sickness response," which we have all experienced, for example when we catch the flu. Profound fatigue, headache, sensitivity to light and sound, and painful joints and muscles, drive us to bed. This sickness response forces us to rest and give the body the opportunity to fight the invading germ. This sounds a lot like the symptoms of many Gulf War veterans. One of the reasons the Gulf War Syndrome may have been so difficult to understand is that glia--the other brain--has itself been such a mystery until recently.
