From the article:
Dr Alasdair Coles, an academic neurologist at Cambridge University, says: 'We know MS is an auto-immune disease because if you block the immune response with drugs, people get better.'
My husband never responded to immune modulating drugs, does that mean he does not have MS? In fact a lot of people don't respond to those drugs...if they did, we wouldn't be looking for a different solution.
At the end of the article, it lumps a few different ideas together, as though they were wrong or wacky...they include Vitamin d playing a role, which is showing to be correct and not wacky at all, it's just we don't bother taking it, until it is too late.
