I am under the impression that they did not find anything on her MRI. It was not uncommon for MS to be misdiagnoed back then. MS was a blanket diagnoses after they rule out everything else. I just read a book that claimed that a Candida overgrowth
was the cause for MS she treated the overgrowth with antifungals and diet modification. I am not convinced she ever had MS in her case but the symptoms for candida overgrowth do mimmic the symptoms of MS. The frequent use of Antibiotics , steroids and other things create this condition and may be helpful to you. Personally I do regular acupuncture treatments and have found them invaluable for reducing some MS symptoms. I wish you and your aunt the best of luck!
