Could Medicine be catching up? Make it so!
I haven't looked at the eMedicine definition of Chronic Fatigue Syndrome for a while. Low and behold, they actually said this in the first definitional paragraph:
Really! Go see for yourself. They even mention Chlamydia pneumoniae in the article. As one of the potential causes for CFS. I just about fell out of my computer chair. eMedicine is considered a "standard of care" reference, so this is a big deal. Their lit review on the immune and other abnormalities in CFS is also quite good.
