First of all, please know that I have no medical background.
Even if the MRI showed brain lesions ("white spots"), this is not conclusive evidence of MS – there is no definitive test for MS. Brain lesions are consistent with
many conditions (as are all the MS symptoms) – including, for example, migraine headaches… And yes, even a vitamin B12 deficiency.
MS is a diagnosis of exclusion, made
only after other more likely causes for the symptoms have been ruled out (but, no doubt, Eric's doctor has done this). Gluten sensitivity (or even celiac disease) is one of those to be ruled out.
