CFIDS/ME diagnosis breakthrough
I think this is the most on-topic diagnosis tool I've seen.
and here's a nice summary of the legal implications of the test
There is a disease characterized by protracted recovery from exertion. It doesn't have a name. It used to be what was meant by "CFS", then by "CFIDS".
There is a continuous push by the CDC and others to widen -- and thereby dilute -- the definition of CFIDS. They've proved repeatedly that if you throw "anyone with protracted fatigue" into the definition of the term, then you can "cure" most of the (added) sufferers with Graded Exercise and CBT. It is a scam, but what's new in that?
However, this back-to-back test of cardiopulmonary capacity gets right at the heart of the problem -- protracted recovery from exertion -- measures that, and provides pretty tough-to-fake documentation of the symptom.
I am going to ask my doctor to perform this measurement. I don't want or need disability compensation, thank God. I could have, though, if I hadn't found an effective treatment. I want him to measure this so that I can measure my progress.
