There is a particularly higher rate of ALS among Gulf War vets of 1990-1991 which has caused the VA to get involved. I'm one of those vets (did 20 yrs in the navy) and have developed symptoms that mirror ALS. So far, the neuros haven't been able to make any kind of difinitive diagnosis. Theres the weakness, hyperreflexia, stiffness, twitching and some atrophy in my right arm that may or may not be attributable to the rest of whats going on. Anyway, in the military, your sleep pattern is constatly being disturbed and stress levels can go through the roof. Oh, not to mention diet! The food isn't exactly lean cousine kind of stuff. But, I'd do it all over again in a heart beat (which I may not have a whole lot left - lol).
