This discussion makes me realize how little science knows about MS. How do they know those with vapid smiles are suffering internally? How on earth? Yes, posting the study might be worthwhile.
I have learned over the decades that the knowledge about MS and other neurological diseases is poor. The only thing I go on is "what works". Some people seem to do marvelously on LDN and I wish I could take it, but unlikely to work for me because of my Porphyria. The Swank diet works for me because it's obvious that my symptoms increase if I get off it for more than one day. I start to stagger if I get off it when traveling or something like that. So that's another "what works" for me. I would definitely try LDN if I could take it.
