(Long post)
AYME and Professor Crawley are very clear on our position, we do think that ME/CFS is a biological condition and much research needs to be done to determine the exact cause and treatment. We do not support the hypothesis that ME/CFS is a psychological disorder. However, a complete understanding of ME/CFS may be decades away and we cannot allow nothing to be done for children and young people with ME/CFS in the meantime. There is promising research happening at the moment, but even if the exact cause is determined soon, it may take a long time for a treatment to be available.
The way in which Crawley defines her patients is guaranteed to
1) ensure that the cause of the disease is never found because its a non-sensical grouping of patients
2) ensure that at least some of the patients will benefit from the therapies she is pushing because her cohorts include such a range of unrelated conditions, allowing her to claim that she is helping "ME/CFS" patients
Her claim that one in 50 teens have CFS is based on a study of parent reported chronic fatigue. And the FITNET study uses the NICE criteria, which she defines to be 3 months of fatigue plus any one of a list of 9 symptoms. Exclusions are listed as "conditions that explain the fatigue" - it doesn't specify any psych conditions as exclusionary.
No way of knowing what these patients have. Her cohorts are clinically meaningless.
MEGA is using the NICE criteria? Will MEGA be using it in the same way that Crawley is using it in FITNET? Or will MEGA leave it up to each researcher to apply the NICE criteria however they want?
