I am 51 y. old, live in Israel and was diagnosed with Spino-cerebelar Ataxia in 1994. Supervised by a Neurologist. I take vitamin E plus other vitamins B1,B12, etc. Am treated mainly with muscle relaxants. Walk very slowly and since last year with the help of a cane, (equilibrium, balance). So far no progression nor regression. In my humble opinion, you daughter should see a Neurologist. J.K.
