MY husband's neurologist here in town. told him when he was diagnosed at 47, he probably had symptoms 10 years prior to that age, but they were not severe enough to go to a doctor. Of course, as you look back, there were things that you may have noticed and just disregarded. Makes sense to me.... I think old age(elder years) hit when you are no longer productive, amazing when it comes at 52 or 55, or even younger. Gerrry Haines
