Sasha has replied succinctly, here’s my waffle
ME wasn’t treated as biologically physical or biologically driven psychiatric in the way you describe
@Jonathan Edwards or in the way anorexia or schizophrenia might be now thought . The biological aspect of the BPS model was either ignored or thought preliminary, the trigger, or minor or generally insignificant, unimportant. Wessely , who cares about viruses, we just keep on keeping on with effective rehabilitation, paraphrasing.
The illness or “condition” they would probably prefer, in terms of biology was a combination of dysregulation, reversible through behaviour, deconditioning, reversible through the behaviour, sensitisation, reversible through behaviour or exposure, mild but inconsistent immune stuff, who cares if we can reverse it through behaviour. It wasn’t talked of in terms serious immune challenges being looked at now for example t-cells, the mitochondria dysfunction idea was sneered at, although it now could be widespread and all the other stuff, serious ANS dysfunction etc. Our biological abnormalities weren’t serious and often largely irreversible like other illness.
Our unhelpful beliefs on being “physically unwell” and therefore unable to do exercise were more just irrational (we are western self obsessive, female) , learned behaviour (from unhelpful support groups and a more sick sounding name ME) and so on, not driven by paranoia or depression or OCD type thinking, hence our being supposedly easy and cheap to fix Ie with a nurse trained briefly in CBT “reassuring us” there was no genuine obstacle in completing a graded activity program except our beliefs (FITENT) and that we just had as a difficulty a circadin rhythm disturbance or such. There are apparently psychological and social causes of beliefs, ie the belief that people of a certain race are a certain way is learned not driven biologically. That’s why I think the term unhelpful beliefs was used, they were simply unhelpful, easy to drop, re educate. We didnt need Drs or psychiatrists generally, or medicine, just an OT to inform , reassure, motivate and encourage. How appealing to the government, 250,000 rehabilitated by the cheapest health professional. People like Blakemore might have called ME a brain disorder but there was no brain research.
ME neglect was driven both by the belief cheap rehab was effective and that there was ” no organic cause” to use the language of MUS. Establishing to the medical community that there is organic cause after all or serious biological abnormalities (if they mean the same thing) seems crucial to me. I suspect organic and biological abnormalities mean different things as said above, so perhaps organic is better term as long as there’s agreement on it. Crawleys abnormalities are such as reversible inflammation which graded exercise supposedly will treat not exacerbate - many outside the group of mild, new, recovering, will struggle to find that sort of exercise because of their other biological abnormalities
