Thanks! I think that Crawley does think CFS can be 'physiological'. Classing it as 'physiological' doesn't need to mean much though, and imo is largely a distraction from the real problems with the way people like Crawley apporach patients. TraditionAlly there is an assocation between classing patient's health problems as 'psychological', and approaching them in a manipulative and 'paternalistic' manner, but there's also a lot of people who think that it's okay to treat those with 'physiological' problems in the same way. Crawley's shown that she's a quack (see the links in my signature!) regardless of what she thinks is the likely cause of symptoms in CFS.
