My Neurologist practically changes his mind about whether I am PPMS every time I go in. I am not on a DMD because I have had
MS for 47 years, have PPMS, and it is very slow, The CRABS would not do me much good. I was set to go on the new ones but with cancer I can't be on a the new drugs. I was told progression happens with or with out symptoms. Nothing can guarantee to stop progression but I think it is important to try.
