i had symptoms such as l'hermitte's for a long time prior to my snowboarding accident. i also had various problems like numbness or lost coordination or weakness which always resolved if i would bother to take my b12 for a few days. subacute combined degeneration of the spinal cord results in thoracic and cervical lesions that are really only distinguishable from ms lesions when you throw in other things like oligoclonal banding. which i have. without further testing for specificity, all the bands indicate is chronic cns inflammation which is not typically an issue in cobalamin deficiency. but there are other factors besides b12 in play in my case, such as the candida.
i refer to my condition as ms because the doctors have placed a check mark beside each item on the list of conditions that are required for ms diagnosis. mind you their differential diagnosis regarding cobalamin was a bit off but whatever. i have all the check marks.
regarding turning it around, i did say manageable, and potentially
reversible. i have read too many accounts, both anecdotal
and in the context of peer reviewed studies, of problems corrected and symptoms resolving, not to believe that some aspects of some forms of ms are manageable and indeed reversible. i mean here alone you must have read about sarah's treatment and dave's approach. i'm not saying that i think any single approach would definitely work for each patient. in my particular case, we will just have to see if my attempts to fix things are successful.
all in all, i don't think the definition of ms is in any way clear and specific enough to make generalizations like 'irreversible' about the disease as a whole. we shall see!
