Brain plasticity is very real. I see that someone has brought up Jill Bolte Taylor, and Norman Doidge's book (well worth the read).
I believe that i got this link - http://www.positscience.com/
- from Doidge's book, and although they are selling something, they offer a lot for free too.
I read on another thread that the person writing thought that RRMSers who were younger would heal better. I'm not sure that I would agree with that. I think that they may heal faster, but not necessarily better. Bolte-Taylor was not "young" when she had her stroke, and although she has not completely recovered (yet), her recovery is
remarkable. I am 48 years old, but I am in very good health (besides MS, and being a "heavy" smoker). I still recover very quickly from any injury, and it is almost impossible to bruise me. I have rarely been sick (besides amoebic dysentery, Giardia and e-coli - the hazards of Third World travel) Dietary support is, I believe, critical.
There are still quite a few Model Ts around, and they are older than most of your grandmas... I don't believe that age is always a determination of health.
