There seems to be a desire evident in the commentary on this topic to categorise CFS as either completely psychological, or completely physiological. My own experience, having had the condition for much of the past 10 years, and having (after many years of frustration) found treatment methods that have enabled me to achieve almost full recovery, is that it is very much both physiological and psychological, and that only by treating the mind and the body together can full recovery be achieved. Whilst many people will want to read this study as evidence that CFS is fundamentally physiological in nature, it doesn't do anything to dismiss the role of psychology as a causal or perpetuating factor. It is equivalent to using a lab test indicating (for example) imbalances of serotonin as evidence of depression, without taking into account the many years of stress and trauma that may have led up to the issue manifesting as a physiological (and debilitating psychological) condition. Whilst I have no doubt there is scope to develop treatments that can ease CFS sufferers' physiological symptoms, and I hope research findings like this can help to bring about these kinds of breakthroughs, I have no expectation that a comprehensive remedy for CFS can be found that doesn't include profound psychological healing as a key part of the treatment. It also occurs to me that a major reason why this condition continues to evade explanation and treatment by mainstream medicine, is that the profession is unaccustomed to looking at things as both psychological and physiological in nature, and that it will take a change in mindset on this to pave the way to discovering effective treatments for CFS and other such "mysterious" conditions.
