CBT/GET is ineffective and potentially harmful.

ME/CFS patients seem to die considerably younger.

As has been established by the Bagnall et al. (1) and the Price et al. (2), the solution proposed by Santhouse (3), cognitive behavioural therapy (CBT)/graded exercise therapy (GET) reduced "fatigue severity" in 40% of chronic fatigued people, in contrast with 26% in usual care.


Taking into consideration the placebo effect, the fact that a reduction in "fatigue" is not reflected by objective improvement (4, 5), the fact that the evidence base for CBT and GET is almost non-existent, etc. one must conclude that CBT and GET is not effective.


Moreover, as established by large patient surveys, e.g. (6, 7), and by clinical practice (5), CBT/GET has a negative effect on the symptomology of many ME/CFS patients (pain, muscle weakness, neurocognitive impairment etc.)


This can be explained by the fact that exertion, and thus GET, intensifies the pre-existing pathophysiology: inflammation, immune dysfunction, immunosuppression, (persistent) infections, oxidative and nitrosative stress and their sequels, e.g. mitochondrial damage/dysfunction and a disturbed circulation (8, 9).


All in all, CBT/GET is a non-evidenced based therapy and even potentially harmful for many ME/CFS patients (10).


Santhouse also asserts incorrectly that 'the greatest risk to life is likely to be suicide' and 'this is often linked to depression that can be effectively treated'.


A study into the causes of death by a Jason (11) established that ▒20% of the patients had died from cancer, ▒20% had died as the consequence of heart failure, and ▒20% as a result of suicide.


The mean age of those who died from cancer and suicide was 47.8 and 39.3 years, respectively, which is ▒24 years younger than those who died from cancer and suicide in the general population.


The pathological abnormalities established in ME/CFS repeatedly plausibly explain an increased risk for cancer (12)and heart failure (13).


Certainly it is warranted to treat depression in ME/CFS.

However, successfully treating depression, e.g. by antidepressants, has no effect on characteristic physical and cognitive ME/CVS symptoms (14, 15, 16).

In conclusion, the comments made by Santhouse do not seem to be very appropriate.


Ironically, the CBT/GET mantra by Santhouse and colleagues and denial of serious biological aberrations is exactly the reason why many patients feel that 'the medical profession has given up to them'.


It is about time the medical profession takes this devastating illness seriously by exploring the biological abnormalities in depth and developing effective therapies aimed at these aberrations.


So the death of Lynn Gilderdale and many others will not be in vain.
