Just want to make it clear that having gluten ataxia and then going gluten free is not a cure. For many there is still no medication and only if you don't respond to a gluten free diet are you offered anything.A gluten free diet and a healthy eating approach along with regular exercise helps.
I also take lots of high dose supplements.
Use it or lose they say, it can stop the progression of ataxia, but if like me you have eaten gluten all your life, most of us do, then it still causes atrophy to the cerebellum. This is why early diagnosis is so important!
It doesn't help that many doctors and neurologists don't believe there is such a thing as non coeliac gluten sensitivity.
Good luck all.
