Psychiatric illness presents as behavioural and mood abnormalities

Psychiatric illness can present with all sorts of other things. And neuropsychiatric disorders can often involve severe pain, inability to eat, orthostatic intolerance etc..

Psychiatric illness is a completely different category from 'the psychological model' which is neither psychiatric nor somatic. The likely reason why people with ME/CFS die without being fed is that they are classified as neither medical nor psychiatric. It is actually written into medical guidance as such.

Most people with m.e have clear psychological/ psychiatrist assessment & a host of physical symptoms, such as muscle pain, sore throats,, orthosatatuc intolerance, morphine requiring pain , some that are objective and not explained by deconditioning , such as failure to perform of 2 day testing. . Should be end of. Psychiatric illness presents as behavioural and mood abnormalities, this is not the m.e presentation. This psychological model + de conditioning was pretty much held up solely by CBTGET being deemed effective

It seems Cartesian Dualism has a lot to answer for. I read a really interesting study that highlighted how arbitrary the medical classification system between mental and physical was, in that many so-called psychiatric conditions have significant somatic symptoms whereas many diseases considered exclusively physical frequently can include psychiatric symptoms. It gave good examples, I wish I could find it agsin.

My mum has a very physical gallbladder infection since Christmas that caused mood changes and even psychosis but which was first diagnosed by the hospital as depression and treated with antidepressants. Six months later it's now advanced to severe sepsis stage, and she's been correctly diagnosed in a different hospital. It all happened because of very visible psychological symptoms leading to other symptoms (pain and a possible uti bladder issue) being overlooked so that the medical problem was treated as a psychological illness.

I strongly believe that OCD, ADHD, depression, anxiety disorders and several other psychiatric disorders are related to mitochondrial function and impaired metabolism.

Re Carson: what puzzles me is why he is seen as an expert on ME/CFS. The only relevant link seems to be that, according to Carson's declared interests on the SMC's website he "led writing of the Scottish Good Practice Statement in ME/CFS in 2008" - but how did he manage to get involved in leading that? Searching PubMed for 'Carson A[Author] AND "chronic fatigue syndrome"' gives me two results: the Anomalies paper, and as a co-author on a paper about brain fog (link) so it is not as if he has a relevant publication record.

The picture that emerges from the blood chemistry - high TyG, high TG/HDL ratio, hyperglycaemia (glucose, HbA1c), a modest ALP rise - BMI may not be an ideal metric to use to assess adiposity (waist-hip ratio, perhaps?), and given the results from the other recent Edinburgh paper many of the UK Biobank self-reported lifetime CFS cases are undoubtedly not ME/CFS.

I don't see why ME/CFS should be categorised as neuropsychiatric. Neuropsychiatric disorders surely should involve a disturbance of mood, perception or behaviour and there is no evidence for any such disturbance as being intrinsic to ME/CFS. Brain fog is a transdiagnostic symptom that can be e.g. a sequel of chemotherapy.

Also, some disorders that are widely thought to be purely "all in the head" may not be - anorexia nervosa seems to be widely thought to be a mixture of psychiatric & psychological, and historically it was considered a purely hysterical disorder (once being called anorexia hysterica or apepsia hysterica) - yet a GWAS reported in 2019 (link) showed a metabolic component - unfortunately such findings do not seem to have produced much in the way of follow-up research.

I think the problem is that ME is widely perceived to be neither a physical illness nor a mental illness, but an imaginary or made up illness. It is seen as a set of behaviours rather than a mental/physical illness. It might be compared to a phobia of spiders, which may be deeply rooted and subconscious, but is not usually thought to be a physical/mental illness, more a behavioural adaption that can be unlearnt.

When we say 'it's not all in our heads', we get misunderstood by people (purposefully in the case of Carson et al I tend to think). The misunderstanding is that we're against the idea that ME is a mental illness because of our own prejudices against mental illness. I think it's important to emphasise that we want biomedical research because behavioural and psychological treatments have not been effective.

That said, I think the phrase 'it's not all in their heads' coming from a scientist like Chris Ponting is not necessarily a bad thing. Some Guardian readers and Carson etc. may misunderstand but the majority of people will take on board the simple message that ME is a physical condition not an imaginary one.

Edited for clarity.

Re Carson: what puzzles me is why he is seen as an expert on ME/CFS.

Isn't it just that Carson had a link with Sharpe and subsequently became 'our man in Scotland' for the broader BPS community. SMC cliques are fairly narrow it seems and I suspect do not follow any particular expertise.

I don't see why ME/CFS should be categorised as neuropsychiatric. Neuropsychiatric disorders surely should involve a disturbance of mood, perception or behaviour and there is no evidence for any such disturbance as being intrinsic to ME/CFS. Brain fog is a transdiagnostic symptom that can be e.g. a sequel of chemotherapy.

I am not proposing to 'categorise ME/CFS as neuropsychiatric'. But I think brain fog and possibly other fatures can reasonably be seen as neuropsychiatric effects of whatever is at the root of it. Neuropsychiatric effects of drugs include confusion, memory change, changes in perception. Pain and fatigue may be 'changes in perception' due to chemicals interfering with signal pathways.

For chemotherapy I think brain fog could reasonably be called an adverse neuropsychiatric effect.

Some Guardian readers and Carson etc. may misunderstand but the majority of people will take on board the simple message that ME is a physical condition not an imaginary one.

That may be right but I worry.

1. They will get the simple message but then say 'nah, they are always saying that, you can tell it's in their heads'. (The non-Guardian reader is probably mostly pretty convinced of that.)

2. The argument needs to be used at the right time - which may not be for this paper.

3. Chris is up against a group of people known as the Medical Profession who have spent their lives manipulating language to generate spurious arguments in the way Carson does. A lot of physicians also talk reasonable sense when seeing people with diabetes and ulcerative colitis but even the ones who aren't paid up BPS members tend to do a sideline in language manipulation when they want to get rid of the patient (maybe to a convenient therapist). The paid up ones have spent their entire lives doing this to earn a living and various honours.

I think when the time comes the thing to say is that these data show that this is not an imaginary disease that someone has dreamt up. It is a real biological process the cause of which we now know involves...

In a way the important point is not about whether patients were imagining an illness but whether 'ME/CFS experts' were imagining an illness. If there are genetic data than can be taken as causal, and they are found specifially in the group of people identified by ME/CFS then they were not. Even the Daily Mail readers know that people say they have ME/CFS because some doctor told them so. If the doctors were right then so are the patients.

 

[V.R.T.]

even the ones who aren't paid up BPS members tend to do a sideline in language manipulation when they want to get rid of the patient (maybe to a convenient therapist).

This is the thing I find most chilling about modern medical culture. If you throw a stone you hit a story of someone who's cancer or stroke or MS or whatever was missed because their doctors slickly dismissed their concerns and didn't do the necessary tests.

So it isn't just us that bear the brunt of this toxic part of medical culture. It is causing a huge amount of harm every day.

yes, he and Stone were students of Sharpe. in the SMC's mind, they're essentially interchangeable as experts. Stone was asked to comment on the Wilshire et al PACE reanalysis. The SMC has shifted slightly since the PACE days. Now they'll always have at least one of the ideologues, but they also seem to recognize they can't leave it at that and also need to include someone else reasonable.

“someone reasonable”rather than someone else reasonable I reckon
