Dom, I agree that there is so much more to this disease than the tracking of physical disability
That said, Robbie the info you posted is fabulous, and right on the money.
I find for me that the worse my physical symptoms get the more I miss the full use of my brain.
Where it was at one time the most horrifying thought to me to need assistance with walking, it's way worse and far more scary to feel so many days that I need assistance with thinking!!!
