The Concept of Schizophrenia Is Coming to an End – Here's Why I'm not saying the BPS crowd are holding a significant part of the puzzle for ME/CFS. But it's interesting to note that they have their oar in many other waters too, some of which seem unexpected at first glance. But, nowhere else does it -- the BPS ideology and 'behavioural activation' -- have such downside potential to do harm than in ME/CFS, in my opinion - something that proponents fail to acknowledge and are in denial about. I'm not sure if this will turn out to be the case for ME/CFS or not, for a major subgroup. If it did, then I think that would help legitimise the condition, and make it possible to explain in a few sentences. I don't agree that finding a final common pathway would make investigating different causes academic, though the powers that be controlling health budgets might favour that argument. Yes... sounds about right, I think we can all relate to that one!
