I recent got the "Could it be B12" book. I first read the chapter about B12 and MS. I have been diasnosed with B12 def. AND one of two neurologist insist on making sure I dont have MS as well due to abnormal MRI that shows demylating in my brains white matter. I read in the book that there my be a relationship. Some people with low B12 get MS, but not all MS patients have low B12. Next month I am having another MRI with contrast this time and a lumbar puncture to extract spinal fluid. Just wondering if anyone has MS as well or similar experience.
