Norman, that was a big question when my son was diagnosed'ed with als on March 29, 2006. My son had 5 or 6 dental fillings, all mercury (amalgams?) I did quite a bit of research on als when he was diagnosed'ed, and I ran across this site that stated that mercury fillings cause als. By the time that my son was diagnosed'ed he was afraid to have them removed. I don't know what to think about the whole thing, it is so unfair. Everybody is guessing pesticides, dental fillings, dirty produce ( with pesticides), blunt trauma, what the h-ll is going on? Which one is it, and where is the cure? I even heard that canned tuna is bad, LOL! I am not ashamed to admit it, I AM ANGRY! My son didn't have to die because of all this bs, neither did all the others! Als is becoming more common every die. Pretty soon we're all gonna die from als! God bless everyone!
