My father's significant other had just the beginnings of it a long time ago (est. 10 years or so). Somehow she was able to reverse the minor effects she had, and she does not have it now. I know the prognosis is not good, and you hear it only get's worse, but there was good news for my dad's significant other. I will find out for sure what she did (I'll be seeing her Wednesday night, so it will be a few days before I post).
Hang in there. You're having some tough times!
