From what I gathered getting the procedure done would stop any further progression. It appears that it may be too late for getting much better though once a person leaves the RRMS phase.

The criteria for the trials in the US are asking for RRMS, SPMS and PPMS, so there are no concrete delineations yet, or so it appears as to which of us might be helped or not helped. We should know more in another year.

Better yet, no PML!
