multiple sclerosis
"I was 41 when I was diagnosed in 4/98 and took Copaxone until 9/99. I was one of the lab rats in the original Tysabri trials.  Then the FDA approved it and removed from the market due to PML.  My MS came with a back with a vengeance & I was still on Copaxone.  I got back on Tysabri in 4/07. I am almost 56 now and still working full time. I still go to the gym relatively regularly and lead a good life. If your immune system is okay other than MS, have not taken any nasty immune suppressing medicines and if they test you and you do not have the JC virus its a no brainer.  If you have the JC virus its more complicated.  My MS is still not easy but its my best option. Look at the stats vs. other options.  Good Luck!"
