Yes, a "non-psychological" illness that can only be "cured" with "psychological" treatments and the ever-ready exhortation to "exercise more" and "reduce stress".
Somatoform psychologists will always try their best to explain a physiological condition in psychological terms.
After all, Wessely agrees that ME/CFS can be triggered by viral infection... he just claims that after the acute viral illness causing ME/CFS has disappeared, all the symptoms of ME/CFS remain because the patient has not updated his belief system, and thus still thinks he is ill. Then by some sort of
magical thinking, Wessely and Co rather bizarrely claim that it is only your belief system that creates all your symptoms and keeps you ill.
In this way, Wessely and Co have completely twisted and distorted a physiological-caused condition like ME/CFS into a psychological-caused one, using a bizarre theoretical model which amounts to nothing more than
magical thinking. Amazing that that a purportedly science-based publication like the DSM-5 can have a chapter on somatoform disorders, which in essence are no more that magical thinking!
So no doubt the somatoform psychologists (and their disability insurance industry paymasters) will be twisting the physiology of central sensitization in some contorted way to try to make it fit their magical thinking somatoform views on disease etiology.
But that is not a valid reason to criticize central sensitization.
If we are going to critically appraise central sensitization, it needs to be done by examining central sensitization in physiological terms, and working out if this mechanism might be able to biochemically explain ME/CFS symptoms (and the symptoms other diseases central sensitization purports to explain).
I have not looked into central sensitization much, but from what I can see so far, it seems that central sensitization might conceivably play a role in ME/CFS and other diseases grouped under CSS; but I doubt if central sensitization is the whole of the disease.
And even if central sensitization
is present in ME/CFS, we still need to ask what causes it. That is, what dysfunctional mechanism is behind central sensitization. Causes for central sensitization might include neuroinflammation, autoimmunity, or infection.
