Hi, I was diagnosed with PPMS about 4 years ago.I feel much the same frustration as you.My neurologists,of which I have 3,keep telling me to live in hope.Other than that I am also searching the net for possible cures or medication.I am afraid to say there is little out there.The good news is President O´`Bama lifted the ban on feotel stem cell research in the States.Good ridence to Bush. You will find many sites claiming to have miraculous cures for PPMAS.This is a lot of nonsense.They atre golod diggers attenpting to get your hard earned money,Kings Colledge in London are at present the most advbanced in this field,and they will tell you,they are far from any sort of cure.   I have now lost my sight and am forced to carry a white cane,I dont like it one bit.However it makes my daily lifem a little more bearable. Keep your chin up and keep your hopes alive!
