720L,
The best help you can give your friend, is to make sure they take care of themselves, take their meds, try to avoid stressful situations and get rest whenever they can.
I was diagnosed thru MRI and process of ruling out other possible conditions. I have some walking issues, I won't deny its a struggle many times, but have learned to deal with it. Very grateful to my DH, a very big help to me. My brother also has MS and doesn't take care of himself , medicine or anything, he has progressed some, but is still getting around, we were both diagnosed at 50 , so think I had it, but just didn't want to think it could be a more serious than a back issue. Oh well, I take a daily shot of copaxone and so far " knock on wood ", hasn't gotten any worse, pretty much the same as when first diagnosed.
My thoughts and prayers go to your friend, they will be fine and they have a real good friend.
