At one point a neurologist stated, "you could have a sort of pre-MS"...
Are they inherently by-definition different, as in 'in this particular case, one would exclude the other'?
This paper would argue the illnesses are remarkably similar. The list of labwork similarities makes you wonder how a clinician tells MS and ME apart.
I'm not at all arguing that they're actually the same illness, of course. But they are remarkably similar in presentation and lab data. I don't have trouble believing that MS could coexist with ME. It seems like it would be a very tiny immunological or endocrinological flip of a switch away.
