That would be me, at 48.
And me at 46. Neuro says I’ve probably had it since college when I had a numb arm for about 2 weeks. But it got better, as did all the other weird stuff that happened through the years.
I saw a 2 year study of about 60 plus people in the test group where their disability scores improved making them less disabled. Brain lesions reduced on brain scans. The treatment involved a chemotherapy that has a 3% risk of death and a bone marrow transplant.
