My boyfriend has told me that vitamin E doesn't do anything for him, although I still make him take it just in case. It's still in the stages of being researched as to what effects it has. There is another current study, although I will admit that it sounds a bit crazy but there is supposed to be an antioxidant in blue berries that helps with muscle coordination and motor skills. The best thing that he has come up with is exercise. He was doing martial arts until it became to difficult and now goes swimming as often as possible. His neurologist told him that keeping fit will slow down the progression.
