It's got to be at the mitochondrial level..

Maybe we all don't have the same 'disease' either just a thought.. Seems like they know just as much as Charcot did in the 1800s.. Here we are 150 years later :)

I'm interested in Wahls protocol as it looks at nutritionally dense food to feed the mitochondria, the engine of the cell.

Unfortunately, there are many things researches believe leads to MS. There is not one thing they can point to that is the single denominator.
It might be genetics, however, that doesn't explain others like myself, i have no family history.
Some say its environmentally driven, this is very broad and generalized, what in ones environment causes MS, this is the question?
Some say its inoculations, say Anthrax Vaccine?
No one has the single cause and most likely that one thing that ties us all together is what needs to be answered?

I think MS caused V. D deficiency ,in other word, MS caused a leakage of Vitamin D from the body cause some MSers spent most of their lives (especially childhood) under sun shine in a very hot countries (a friend of mine from Sudan told me so.
I think there's a worldwide air pollution plays a role.
