It is frustrating, I know, waiting for an MS treatment that actually regenerates damaged myelin. There is a lot of research, but I do not know of any successfil regeneration treatments yet.
In summer of last year there was a small trial in Chicago that showed the possibility of nerve recovery. No treatment, but almost promising. A larger trial is now underway.
Look at this section on tne Mayo Clinic site talking about their research projects.
Check this site - Myelin Repair Foundation. It is one good one that follows progress on that topic.
I think this is a good question, and I hope this helps. Let me know how you are doing with this..
