I certainly agree with everyone else, be vigilant - it could be 'chemo-brain'. Having said that, I think that with all the bad press about Tysabri in the past few years, I would think many doctors are somewhat reluctant. Do you know you JCV status? That makes a huge difference, and even if you were JCV+ your chances of PML are almost negligible for the first two years, and if you are negative, you are safe, as long s you have frequent tests. It truly is a wonderful drug.

It might be time to find another doc, who is more up to date, although I understand your loyalty.
