Unfortunately it seems some of the positive aspects of the ME situation in Sweden are repeatedly being overstated. It is true that there is a separate diagnostic code etc for burnout:
However, how ME is viewed and treated in different parts of the country varies a lot, and also between different healthcare centers in the same city.
There's the good but extremely rare examples like the ME center at Stora Sköndal in Stockholm. But there are loads of Swedish healthcare professionals including doctors as well as researchers, politicians, policy makers etc who view ME as a psychological/psychiatric/behavioural/health anxiety/cultural issue, or believe that ME is the same thing as burnout, or who flat out deny that ME exists at all.
Plenty of GPs and even some so called ME specialist centers subscribe to the BPS model, offering CBT/GET and similar approaches. There is a very influential BPS lobby who are given plenty of space in the media/public debate, who get actively involved in political/goverment processes by trying to stop biomedical ME centers from being established or get their contracts cancelled, who actively promote PACE and Per Fink's functional somatic model etc. There is plenty of BPS research into ME happening. There is very strong stigma, discrimination, ignorance, prejudice and contempt. Etc etc etc.
Actually, only yesterday there was a news article in a local Swedish paper (Ludvika Tidning, 14 January. I haven't been able to find it online, sorry.) about the similarities and differences between ME and burnout. Indre Bileviciute-Ljungar, a well-known so called ME specialist and BPS researcher (for example, medical expert of the currently ongoing
the Mind-Body Study), was quoted saying some reasonable things -- like highlighting the current lack of knowledge and the need for more research -- but also things like "One must try different treatment and rehabilitation methods to create evidence and not wait for evidence that can take many years yet." and "you can try a burnout treatment or rehabilitation and see how the [ME] patient responds".
I'd say that's really dangeous advice. Way too many of us have already deteriorated severely and permanently from being pushed into the "illness-denying" kind of CBT, exercise and other kinds of "activating" interventions and experiments
This, by the way, is the kind of people who are actively involved in drawing up our treatment guidelines etc...
The Danish people need to choose their study visit destination very carefully. As I already mentioned, there are several so called ME specialist centers that reportedly have strong BPS views (for example Smärthjälpen in Göteborg and Pain and rehab center at Linköping University hospital). They would have no problems finding Swedish healthcare professionals and politicians that support the functional somatic/MUS or cognitive behavioural (CBT/GET) models of ME, if that's what they were looking for... Please be careful.
