The New South Wales University (Australia) has just published findings suggesting that cfs results from brain damage caused by a virus. The virus clears up - but the brain damage stays and the brain issues all sorts of wrong information which causes the body to develop the cfs symptoms. This is not to say that cfs is imaginary or psychological - quite the reverse. The brain damage is visible. You might like to check this out on the following web site - if I am allowed to show it. Very readable. www.abc.net.au/news/newsitem and go from there. If the web site does not appear you can track down the details by typing in ABC Newsonline or go to the New South Wales University page. Unfortunately, the cause is just a suggested cause and there is no mention of resulting treatment.
