I suppose not. Looks like we just need to dump the word from the name entirely. I'll take Chronic Syndrome over Chronic Fatigue Syndrome any day. I mean, heck, I've got chronic all kinds of things -- chronic immune dysfunction, chronic autonomic dysfunction, chronic infections -- I'm just all around chronic. My impression of the word "fatigue" as it applies to ME/CFS is more consistent with this definition from The Free Dictionary than "lack of energy and motivation". I particularly like the Physiology definition.
