That could still be very interesting. Eg. There are some other illnesses like MS where patients can get fatigued in a similar way to CFS, but not always. If we find a similar response between the fatigued and non fatigued MS patients for example, that could still point to something that is going on causing the fatigue in both cases. Ron Davis’s line on this was to point out having one disease doesn’t mean you can’t have any others. There are a lot of other interesting overlaps showing up. One of the more interesting to me (because I have it) is that about 40% of CFS patients are testing positive for small fiber polyneuropathy on punch biopsies that appear to be autoimmune in origin. Is that itself an underlying cause of some 40% of CFS cases or is it just a common comorbid condition that whatever triggers CFS also triggers?
