Copaxone & Tysabri My wife who has now been on T for ~32 months showed no active disease in her latest MRI. That is a first. (Previously, treated with C for many years.) I set out the history of her progress on T here: http://siliconinvestor.advfn.com/readmsg.aspx?msgid=27015151 On T her deficits were reduced, no more exacerbations and now no evidence of new injury. ij
