I was diagnosed with Genetic Cerebellar Ataxia about 7 /8 years ago.
My job involved a lot of talking, but apart from speech being difficult, my advice is just get on with life as best as you can.
I used to be a runner, (London Marathon twice Great North 4 times)
and countless others. I still" run" 3 times a week so please don't give up without a fight,even if you don't win at least you will have tried .It isn't what you have, it's how you deal with it.
I am 68 and refuse to lie down just yet.
