I see the same neuro as Wiz...at a recent lecture, he discussed the theory out there that the immune system might not in fact be attacking the myelin...that the immune cells go in after whatever causes the damage to clean it up.
He still thinks we'll figure out what actually causes the disease, and has hopes that a cure will be found in our lifetime.

This is an interesting thread...I look forward to more posts as I ruminate on this...
