Well, I will give you a few....
Though it appears much research has been done into CCSVI, remember that thisisms and the internet boards in general represent a small proportion of what is actually going on. Only a couple of people have actually published anything on CCSVI, and repeatability in science is one of the most important things.
In the recent webcast on CCSVI sponsored by the NMSS, both proponents of CCSVI, Dr. Zamboni and Dr. Zivadinov recommended that MS patients continue with their treatments, whatever they might be, whether they have had CCSVI treatment or not. Dr. Zamboni's wife continues to use a DMD (not sure which one). The first 2 patients treated at Stanford continue to use Copaxone.
So, while the decision to use Copaxone or another DMD is a personal one, you shouldn't let CCSVI enter into the decision. The concept is still pretty much in its infancy. If nothing else, you will be buying time until the treatment is shown to be helpful and becomes mainstream.
