Indeed, but using that logic, and without making an exception of it, DecodeME is in the same category. I don't believe that's the case for the study or its cohort, because I think questionnaires can capture valuable information. I don't think these things are widely seen on the net, though...

It's good to have so much debate about the idea of a PEM questionnaire. I just wish my health allowed my health to get involved, but I want to make one comment now (more in the next few days if I can manage it). I think it would help if we brought in data to support or challenge some of the...

Yes, a decent de Unfortunately, the NIH group still endorsed the DPSQ as the way to assess PEM, even though it was clearly describing something for a different. S4ME made a sufficient the NIH arguing in vain that should start developing a better tool.

Um, agree with all that. Yes, 10x higher in Cornwall than in the lowest areas. This study found that nearly half of GPs say they find ME/CFS hard to diagnose, and this questionnaire could help a lot with that. Sounds good. My health means I can't take things forward myself, though. I think...

I should probably have posted this earlier as it's relevant to some of the comments made above. What other PEM questionnaires are there, and what questions do they use? We have the Jason and Chee 2025 paper, and it mentions several other scales. The NIH is developing one, and @Bivoxmentions...

I;ve started a new thread focusing on a potential new questionnaire to identify PEM Should we initiate development of a new, short questionnaire to identify PEM (to aid diagnosis)? Thanks to everyone here who has contributed to the idea, including @Trish @Kitty @ME/CFS Science Blog @Bivox

Relevant data so far on which other illness do or don’t have PEM We know next to nothing about the existence or extent of PEM in other illnesses, despite it often being described as unique to ME/CFS. The term was coined by medics for the 1994 CDC/Fukuda criteria because they knew of no term...

I think it would help PwME if we had a short questionnaire that does a good job of identifying postexertional malaise (PEM), the cardinal symptom of this illness. It could be useful in two ways: 1. Doctors, especially those in primary care, could use it to help diagnose people who have ME/CFS...

Interesting. I haven't looked to see if any of the genes highlighted here match with DecodeME findings. I can't access the CFS page as it doesn't support mobile browsers. How many CFS cases of the reporting from UKB? There are several different UKB definitions available, I think amounting to...

Yes, and it's a nightmare to untangle. The DecodeME analysis restricted itself to people with the white European ancestry, which simplifies things – but not a lot. One reason why HLA analysis is so challenging – population stratification HLA varies enormously even in White Europeans...

My memory is terrible, but I I am not sure the Norwegian study had found HLA alleles that reached statistical significance (merely that they were promising). I wonder when the DecodeME HLA analysis will be done?

I'm not sure the relatively small sample size can support such detailed conclusions. I believe there's a rule of thumb in statistical modelling that you need 10 times as many cases as parameters. I'm not sure how many "cases" we have in this experiment, given that it's looking at male versus...

Congratulations, @Tom Kindlon , on this award from Trinity and that standing innovation of large group of alumni, which made me tear up. If I may say so, you and Orla looked very dapper as well. This is richly deserved – you have achieved so much over the decades.

Interesting. Sian Leary was doing this job, and I would have expected her to be very good.

I agree with the grades don't bounce back straight away". But I think someone who is struggling a bit with lots of illness illnesses, including depression, it might think the symptoms last a long time if they go on for three or four hours, which is the kind of timescale that Lenny Jason, found...

I thought the PEM duration work by Lenny Jason was incredibly useful. I'm not sure about the rest. To me, what we really need is an instrument that researchers can use to identify if people have PEM as it's the cardinal symptom of this disease. I suspect that's not going to happen unless we do...

As far as I know, that's a first. An ME/CFS study with flaky methodology that the editor takes seriously and decides to retract despite opposition from the authors. We need a lot more of this.

I'm not sure much we can conclude from this. The problem with that survey is that it was of the general public, and we know if you ask the general public if they have ME or chronic fatigue syndrome, you're likely to get unreliable results. Louis Nacul found that for a British Columbia study...

This is such a powerful poem, Veronica. I think it's going to resonate with many people with this illness, as it does with me.

My consultant got permission for me to try it years ago when he was running a trial to use it to treat a different chronic condition. It's kind of workedto give me more to give me more energy. It also ended up in a relapse for obvious reasons. A couple of years later, when I was doing better...
