That's amazingly fast work by the scientific community. This Wuhan coronavirus made its first appearance on 31 Dec 2019, and now within 3 weeks, we already have a PCR test for it (according to the WHO website).

It's been discussed on ME/CFS forums before. Here is a paper.

Moderator note: Use this thread to discuss the possibility of an ME/CFS or ME/CFS-like illness following Covid-19. Initial posts have been moved from the Coronavirus - world-wide spread and control thread. (Up to post #840 so far) *************** It's interesting that in the 2003 SARS...

Yes, it depends on what percentage of the population is infected with the virus. And that will depend on the evolution of the virus, and whether it evolves into a form which is more easily transmissible. If that does not happen, perhaps the outbreak will have only a limited impact. Apparently...

So far out of the 300 confirmed cases of this new coronavirus, 6 people have died. So presumably that's a 2% fatality rate. Ref: here. Thus if it does spread to the rest of the world's 7.8 billion population, I guess that's potentially 2% of the world dying, or 156 million deaths. That may beat...

A few studies have found persistent poliovirus infection in the cerebrospinal-fluid and blood of post-polio syndrome (PPS) patients: see this study, this study and this study. Since poliovirus is an enterovirus, there might be an argument for classifying PPS as another form of...

Interesting that one ME/CFS patient obtained the maximum benefits on a dose of 12 mg daily (6 mg two times per day). This is higher that the typical LDN dose of around 4 mg daily. It suggests that if you notice benefits at 4 mg, it's worth trying higher doses to see if further benefits arise.

As Trish hints, you have be a bit careful with this definition of anhedonia, as although ME/CFS patients are unable to do certain things because of fatigue, PEM repercussions, or because brain fog prevents them, that does not mean there is no pleasure in other tasks which we still find doable...

No, rest assured that sickness behavior perspectives of ME/CFS come from the biomedical camp, not the biopsychosocial camp. Sickness behavior is the set of symptoms you get from an infection, hence it implies some sort of infectious or inflammatory process behind it. Michael Maes looked at...

Wow, and by complete coincidence, just after writing the last paragraph just above, I noticed a new post on PR where someone is asking why they have lost interest in their hobbies!

Yes, I think you understand what I mean, that there are hundreds of tiny pleasures throughout the day. Even if I tidy my desk, and then I look at the neat result, it gives a little sense of pleasure and reward. Nowadays thankfully my anhedonia is only mild, so I can now enjoy some of these tiny...

Anhedonia is in essence a lack of (or reduction of) pleasure or reward from normally enjoyable activities. That's it definition. I've only described anhedonia as an "empty vacuum" in a metaphorical sense, because human existence is normally filled full of little pleasurable and rewarding...

I think the question on the NHS website depression questionnaire is reasonably worded: It does not ask about your physical ability to do things, but whether you enjoy doing things. There are dozens of little things you do each day which bring pleasure, pleasures that most people do not even...

I don't doubt that the unscrupulous government lobbying of the disability insurance industry, and particularly UNUM (formerly UnumProvident), which has a presence in the US and UK, played a major role in psychologizing ME. But you need academics to publish papers in order to lend a scientific...

I guess unless you know about anhedonia, you might not get what that question was about. Ideally your doctor would understand the context of the question, and would be able to advise you. I guess each question could have an explanatory paragraph or two, to provide context, which people could...

I am not entirely sure who initiated the psychogenic view of ME/CFS in the 1980s. Wessely's first published paper on ME/CFS appears to have been in 1988 (see his list of ME/CFS papers here). There were counterparts to the Wessely School in other countries: in the US, Bill Reeves of the CDC and...

In the 1970s, we had McEvedy and Beard, who proposed that the 1955 Royal Free ME outbreak was mass hysteria. These guys did not interview or even meet the ME patients of the Royal Free outbreak, so their work was really shoddy. There was some talk about this hysteria idea during that decade, but...

Sounds like nobody understood the purpose of that question. The purpose of the question is to determine if you are suffering from anhedonia — the loss of the ability to enjoy activities which you previously found enjoyable. Anhedonia can be a symptom of depression (though anhedonia is not...

Absolutely. These articles help explain how a tiny group of psychiatrists, with Simon Wessely being the chief protagonist among them, managed in the 1980s to convince most medical researchers and clinicians that ME is an "all in the mind" psychogenic condition. Previously ME had been largely...

The term "reactive depression" that Prof Edwards mentioned above I think is the correct one here, and a better term than psychogenic.
