It just sounds like another one of these things where maybe there is a subset of patients Dxed with MS that actually don't have MS, but instead lingering damage from a head injury. The same can be said for the CCSVI theories...maybe the people being helped by it really didn't have MS, but instead a vascular condition with symptoms that mimiced MS? The autoimmune angle is just too well established for there to be some cause that is totally devoid of any autimmune processes.
