I could barely comprehend the ICC critirea, so I guess that is evidence of neurocognitive problems??? Anyway, as far as I could tell I qualify for both, but it doesn't matter. After eight years I still don't have a diagnosis, it doesn't look like I will ever get one. I asked the doctor today if she believed CFS was a real disease. She said no. As you can imagine, our discussion rapidly went downhill from there! It ended with each of us firing the other. She said the tests she ordered don't show anything wrong, so there isn't anything wrong - I just need a psychotherapist and exercise. She got extremely indignant when I asked for a cardio stress test, VO2 max, etc. Her patients are not allowed to ask for tests. What an arrogant, ignorant attitude!
