My wife has postcovid and this is a profound effect. Yesterday she tried to add up a series of numbers by heart, and she simply couldn’t. For context, she’s pretty mathy and used to mock me for taking out a calculator or a spreadsheet for stuff like that. She also forgets everything, which is another thing she used to be great at. It’s pretty confronting, especially now that the idea that maybe this isn’t temporary is taking shape.

Australia has a population of 26 million, longer life expectancy than the USofA, and comprehensive medical records going back many decades.

With ~98% of the population COVID vaccinated multiple times any vaccine effects would stick out like dogs balls.

If anyone wants to posit "vaccines cause { stupid | strokes | etc }" Then such correlations should be readily apparent in the before | after records of 26 million test subjects.

Australia's excess death rate is still higher than pre-covid: https://www.abc.net.au/news/2023-12-20/mortality-rates-austr... . If the Australian government released the data it'd be trivial to identify whether these deaths were concentrated in the vaccinated or the unvaccinated, but so far it hasn't released such data (if it even possesses such data in aggregate format).

The UK ONS data used to have the obvious flaw that people dropping dead 3 days after their first dose were defined as „unvaccinated“. In this regard, the significant uptick in deaths in summer 2021 in „unvaccinated“ looked interesting to say the least.

How are they doing their definitions now? Could not find it.

Meanwhile this new Dutch data looks quite interesting, maybe someone here would like to give it a shot:

By now there is a hell lot of data pointing at issues with the novel pharmaceutical product. Meanwhile governments all over the world continue to be reluctant to issue data on e.g. „long covid“ or immune system problems in vaccinated vs. unvaccinated, although this data would settle the debate once and for all if its outcome is in favor of getting the shots.

„Fact checkers“ have been shown again and again to be politically biased up to active manipulation. Only people who always agree with the politics they want to push have not noticed at this point.

where the first paragraph in 6.4 translates as follows:

The analyses show a lower or comparable likelihood of dying from causes other than COVID-19 in the first weeks after receiving a COVID-19 vaccine, compared to the vaccination status before receiving the respective dose. This holds true for all age groups and also for long-term care users. Based on these results, there is no population-level evidence that COVID-19 vaccination increases the risk of death due to an adverse reaction.

Oops. Well, you tried.

I see anger, insults, trampling onto what an obviously fascist authority teached them at the end of 2021 is „below them“ to elevate oneself. Ignorance of obvious data, sidelining.

By now I have seen enough actual data - and on top of that a lot of sad „anecdata“ in my direct surroundings - to pay attention at least. Given its prevalence I am sure you have seen the anecdata as well. Have you called someone who claimed to have a vax damage or who told you a relative died from the vax a „conspiracy theorist“ yet?

One good alternative point to start your journey in 2024 could be the US civilian labor force disability data. And no, I won’t waste time to search for that for you, given that you began your „response“ by attaching a label because it soothes you mentally.

The Dutch data has the same problem as the ONS data that I describe in my other comment:

> For the first mRNA vaccination, almost all [hazard ratios], for the different weeks after vaccination and different subgroups, are significantly lower than 1, which indicates a reduced risk of non-COVID-19 death shortly after vaccination.

Obviously vaccination is not supposed to reduce your risk from things unrelated to COVID-19 yet in their data it does. This isn't because it's some magical cure-all. It's because their data is biased. The correct hazard ratio is found only in the 12-49 age group.

As they say in their discussion, this is because "in the event of a very short remaining life expectancy, (a subsequent dose of) COVID-19 vaccination may be decided against ... Vaccination is also postponed in the event of a fever ... This is also called the 'healthy vaccine effect' and it is difficult to correct for this in observational research ... the results should be interpreted with caution"

They also have the problem that "people who have been vaccinated, but have not given permission for registration in CIMS, have been incorrectly classified as unvaccinated (5 to 7 percent of the people)" which means that "This will have influenced the analysis of the risk of death after the first vaccination, because in this analysis the unvaccinated person time served as a reference"

So this dataset is not usable for detecting vaccine side effects or induced deaths. It is a hopelessly corrupted dataset in which large numbers of people are misclassified and it's not a randomized study.

But this is public health research, so after saying results should be interpreted with caution they go ahead and make the totally incautious claim that "Based on these results there are no indications at a population level that COVID-19 vaccination increases the risk of death due to an adverse event." which is a false statement. Their data doesn't allow them to draw such conclusions.

The reason this topic is neuralgic is because if you want to be scientifically correct then you can't actually know whether vaccines reduced deaths or not, but people really want to believe they did. The trials that were supposed to unambiguously measure this failed, in the sense that they showed no effect on deaths and yielded incorrect conclusions about reductions in infection rates (the number started at 95% effective and then was regularly revised, this is not supposed to happen and was due to their time windowing problems). Then attempts to measure it using mass datasets collected outside of RT context all yield incorrect conclusions due to dataset bias, but are presented as definitive anyway for political reasons.

Science is truly in a bad shape :(

Thank you for this summary. I have seen some analyses (including from the „pro vax“ side, even though it is to be despised for their fascist behavior alone) that made the Dutch data appear more useful for these questions. But tbh, what did I expect - last time I checked the Dutch government still voted against doing an honest investigation into the ongoing excess deaths too.

Is there any official data of this kind you would trust right now?

To be fair, I have seen enough by now; the main open question for me is what role endemic covid in all those believing the cure-all narrative and going out partying before milder variants came out played.

The ONS data cannot be used that way unfortunately, and the ONS themselves have admitted to that fact. If you take the ONS data literally then COVID vaccines are a magical elixir of luck that protect against every cause of death including car crashes.

There are at least two problems:

1. The statistically invalid time-windowing games the public health agencies all played in which people who had taken vaccines were classed as unvaccinated. The sibling comment talks about that. Prof Norman Fenton has shown how this yields incorrectly high calculations of effectiveness.

2. Healthy vaccinee bias, in which people who are about to die aren't vaccinated at all because there's no point, and the sort of people who take lots of vaccines tend to be obsessive about health and risk in other ways.

Problems like these with observational data are why drugs are put through trials before being launched to market. If we check the data for say the Pfizer trial, what we see is no effect on mortality and serious problems with statistical power also, simply because so few people were dying of COVID it was basically impossible to run a trial large enough to prove it had any effect.

The statistically invalid time-windowing games the public health agencies all played in which people who had taken vaccines were classed as unvaccinated

As I have just replied to the other commenter, the ONS data he appears to object to categorises various "vaccinated" categories starting immediately after vaccination. The regulator's reply to Fenton makes this clear: https://osr.statisticsauthority.gov.uk/correspondence/ed-hum...

I assume this reply is what you refer to when you say that the ONS admit the data cannot be used that way. However, since that reply, the ASMR calculation now uses data linked to the 2021 census which covers around 91% of the population. Paul Mainwood graphed the ASMRs here: https://twitter.com/PaulMainwood/status/1627979309812965381

I see no evidence here that being vaccinated makes you more likely to die, which is what the original thread was about.

Humpherson simply says that "ONS ... do receive data in [people within two weeks of vaccination], and that the individual would fall into the ‘vaccinated’ category" which is a meaningless tautology, as the entire argument is about the definition of vaccinated used by the public health agencies.

Invalid definitions are a very real and pervasive problem, not only being standard in the public health literature but also standard practice for public health agencies. Fenton has compiled a partial (!) list of papers and studies which do this:

https://wherearethenumbers.substack.com/p/the-very-best-of-c...

Note that UK HSA and studies using ONS data are shown to use invalid definitions.

> the ASMR calculation now uses data linked to the 2021 census which covers around 91% of the population

They say it does, but the UK government doesn't really the true population size. They've admitted this in the past. The 2021 census is unlikely to have solved it given that the civil service doesn't really want to know (if they could actually get full coverage, then they could identify every illegal immigrant). This showed up badly during COVID where more people came forward to be vaccinated than theoretically existed at all in certain age groups. They also told people that only a small percentage of the population was unvaccinated, but when the BBC commissioned a poll as part of a programme they were making (on misinformation!) around 25% of respondents said they were unvaccinated, a huge gap.

So the data quality here is of garbage grade in almost every respect, which is a scandal. People who just tune out and decide nothing governments say on the topic can be trusted are well within reasonable bounds.

which is a meaningless tautology, as the entire argument is about the definition of vaccinated used by the public health agencies.

The ONS mortality stats linked to by kadkadels at the start of the thread contain data related to people who received at least one COVID vaccine (counted from the day they received it, subdivided by time since reception and number of boosters), as well as an unvaccinated category who never did. This is clear to anyone who read the link that kadkadels posted.

Both you and armchairdweller falsely claimed that the unvaccinated category included people who received the vaccine less than N days ago, presumably because you believe that some deaths caused by the vaccine shortly after people receive it are hidden by these stats. But in fact, the vaccinated category starts from the day of vaccination, the unvaccinated tended to die more back when COVID was new, and the ASMR for unvaccinated and vaccinated converged by about the end of 2022, presumably because we've nearly all had COVID at least once so being vaxed now isn't doing a whole lot of good. Both the "vax did more harm than good" crowd and the "we should still be wearing masks" crowd are wrong.

Fenton is in HART, and HART are off their collective rockers, as we knew pretty early on when their internal chats were leaked. See https://www.logically.ai/articles/hart-files-anti-vaccine-my... and https://twitter.com/_johnbye/status/1421397013078360064 for example, and my own small part in pointing out that all the astroturfing groups identified by Neil O'Brien MP were hosted on a single IP address (HART almost immediately moved, lol): https://twitter.com/nameandnature/status/1352998804832870402

Though the prime mover, Narice Bernard, seems to have moved on to newer conspiracies involving "climate lockdowns" and "15 minute cities", people who conclude that nothing HART say on COVID topics can trusted are well within reasonable bounds.

To clarify the claims: The main problem with time windowing is in the effectiveness calculations. That claim isn't specific to England or the ONS, it shows up in many studies and countries.

The main problem with UK-specific death statistics is that they (the ONS) don't know the true size of the denominator.

Regardless of the above, due to widespread intellectual corruption in academia and public health, virtually no data on the topic of COVID or COVID vaccines can be taken at face value.

> Fenton is in HART, and HART are off their collective rockers

Your link says those messages came from a public chat room that literally anyone could sign up for. So Fenton has published things on a website that hosts a chat room where other people said things you disagree with. If that's your best counter to Fenton, and not some issue with his methodologies, then it's safe to assume you concede his points are correct.

We are not talking about vaccine efficiency or efficacy here though but adverse events specifically.

If we check the data for say the Pfizer trial, what we see is no effect on mortality

The point is that there are almost no serious adverse events occuring post-vaccination. There is no pharmacovigilance safety signal or concerning pattern wrt MRNA-vaccines. As we have seen in 2021 with the astra zeneca vaccine, post market surveillance worked and it was promptly investigated as soon as a safety signal emerged. EMA (and other regulatory agencies) communicated transparently about their findings and decisions.

Thank you for reminding me of this fine example of post-market surveillance, I almost forgot :)

vaccination gives immunity to virus or that there are no side effects from vaccination

Who claims that? Nobody does or did. This is a familiar tactic: shifting the goalposts from vaccinations have very rare side effects and do not guarantee one hundred percent immunity to complete immunity and no side effects at all. Rarely does a vaccine provide complete 100% immunity from a disease, in rare cases it does, e.g. Polio. Also nobody ever claimed that vaccines have no side effects, they are just very, very rare. So rare that the expected benefits far outweigh any risk of side effects.

Sweden let Covid go through their population in 2020. New Zealand allowed Covid to spread only in 2022. Both countries vaccinated their population during 2021. Sweden had a wave of excess deaths in 2020. In New Zealand, excess mortality started to increase in 2022. Excess deaths are correlated with the times of Covid waves, not with vaccinations.

I didn't downvote, but I'll answer anyway: there was a propaganda campaign of unprecedented scale espousing the "safety" of these covid vaccines (which didn't go through the normal, rigorous testing process that vaccines usually go through). The propaganda was so successful that a large percentage of the population is still fanatically making false claims about vaccine safety, despite the large number of people who reported serious adverse side effects. At this point pretty much every person on earth knows at least one person who has "long covid symptoms" from the covid vaccine. And yet we have a bunch of people re-enacting the propaganda of 2021 and downvoting any comment that talks about vaccine side effects...

Most of them seem to be convinced it was because of finally getting infected (just scroll around this page for a bunch of examples), and I think they're half right. Late 2022 there was a paper about how the mRNA vaccines caused the body to produce more IgG4 antibodies*, which, simplified, are a sort of "stand down" antibody meant for things like dust and pollen.

I think in at least some people the mRNA vaccines appear to work by suppressing symptoms (which also explains Pfizer's 95% effective, in that trial they only tested people who actually showed symptoms first), but actually they allow the virus to run rampant when the person is eventually infected. So the association is with the virus instead of the vaccines, and they assume it would have been worse without when we just really don't know.

The earliest vaccines injected at tiny amount of the disease, from smallpox on. So she probably expected to feel like shit, and that's why she felt like shit.

However the covid vaccines did not have any covid in them. So there is no way she got a taste of covid shittyness.

Most traditional vaccines consist of either killed or weakened forms of a virus or bacterium. These provoke an immune response that allows the body to fight off the actual pathogen later on.

Instead of delivering a virus, RNA vaccines deliver genetic information that allows the body’s own cells to produce a viral protein which stimulate the immune system to mount a response, without posing any risk of infection.

I would be careful with some of the self-help groups. They can reinforce symptoms rather than improve them. A case in point is a friend of mine who thought she had post-covid symptoms and cognitive decline. She went to a similar group and found a lot of very miserable people with depression. When talking to them they had similar stories of lost relatives, lost jobs and general social decline. But all had a common thing which was they weren't dealing with those issues in a healthy ways. It was turning into a drinking club pretty much after the event was over. Even if you had problems this would exacerbate them over time.

There was a hefty dividing line among my friendship group after covid which was people who went down that route and people who went down the health and fitness route. The latter seem to be doing much better in all aspects even if they started in the former group.

I was running 10km once a week before. It knocked me off my feet entirely and I don't run often now which got to me for a few months. But I fought it and can do that again now if I need to. It hurt that it did that to me but it taught me how fragile things are. Also to note I'm a qualified mathematician but some days to months I can't add numbers together and this turns out mostly to be I'm tired or not in the right state of mind rather than anything persistent. Lots of causes - best to look for the obvious ones first.

I'm pretty scared to look into many mental health issues. I know a buddy who had a super mild case of tourette syndrome but after he researched things started getting worse.

On a similar note, I had some mild PTSD symptoms until I looked into it, then I started having additional symptoms(or at least I was noticing them now). On the flip side having ChatGPT4 combine my PTSD with phenomenology, positive psychology, and CBT, I think I'm close to cured. My favorite part was being able to disagree with chatGPT. When I disagree with humans, I feel like I was getting stuck in a loop.

Yeah, well aware. Fortunately her group is an impressively can-do-attitude bunch, and she’s getting very concrete ideas from it. I think it helps that it was organized by a government-y instance who did some checking, and isn’t some facebook group turned physical or sth.

(Also, no drinking. That would be madness. Nobody in that group drinks at all anymore, it would set back their recovery by a lot)

For example, she had a cold last march which totally knocked her remaining bits of physical energy out of her, and she worried that she wouldn’t be able to come on a planned family trip to the zoo, because of the lengthy walking involved. She shared that worry in the group and another woman said “but then just rent a wheelchair at the entrance and get yourself rolled around most of the time! That’s kinda confronting, “I’m now a person who sometimes needs a wheelchair”, but it’s also very constructive and awesome if you get over that and it helps you get out of the house. We did that trip, it was super awkward (esp when she stood up from the wheelchair and everybody could see that well actually, her legs work fine), and we had a great time and for the first time after a big outing she wasn’t sick in bed for 3 days after.

Btw, a sidenote, “just go sporting” is terrible advice for people with heavy postcovid. Look up “post exertional malaise”. You gotta build it up very carefully, never push yourself too hard. It’s very hard but it appears to work (given enough patience).

Don't worry about it being awkward, there are many reasons for being in a wheelchair besides not being able to walk at all. I mean, the fact that wheelchairs are provided at the entrance indicates that there is a demand from individuals who can walk to access them.

My wife who is more than 2 years sick with Long/Post Covid, lost almost everything because of it, her body and her brain. She had almost perfect memory and spoke 5 languages fluently by the age of 30 while learning Chinese as a 6th. She had a promising career in the medicine field and was also quite a good painter and other crafts (not famous though). We were hiking regularly to very high mountains and doing a lot of activities.

Now she spends most of the day in bed and the rest on the sofa and she can’t barely do anything, only crochet… maybe some cooking. Not even watch movies that have too much action, so she is watching black and white series now to have something to do without getting cognitively burnout. She lost her memory, her capacity to think, she has chronic fatigue and many other weird symptoms like easily getting senses overwhelmed by simple noises or smells.

We went to a lot of doctors, tried a few “remedies” from small scientific studies and internet: metformin, nicotine, lidocaine, multiple supplements and vitamins, some antivirals and many other things. Nobody is able to help her and most of doctors don’t even try to help or know anything about this new and growing condition.

Of course always the “psychosomatic” smart ass appears, but there are enough proofs already to tell them to shut up. Even the NIH director mentioned viral persistence found body tissues in a recent talk [1].

At least the awareness is growing and there are s lot of studies going on. So still some hope, but it won’t come fast.

I got infected with COVID twice, thankfully only after being vaccinated and didn't experience heavy physical effects but the cognitive issues I had on my first infection triggered a really bad anxiety.

At some point I was playing chess with my girlfriend after 4-5 days from getting symptoms, after 3 moves (so pretty much still in the beginning of the openings) my brain simply could not understand what I was trying to do, like I couldn't connect a previous thought to the next, there was an impassable barrier between these thoughts that I couldn't get through.

It got worse when I realised I had no idea what I was doing and while looking at the board I couldn't remember how the pieces moved, I looked at my bishop on the board and couldn't think where it could go. I started to cry, my whole job is to think things through, connect diverging thoughts, I got extremely scared I was going to lose this basic ability that enables me to do my job...

I lost the senses of smell and taste for about 10 days so definitely had neurological issues from COVID, the feeling of not being able to think properly was the worse of the feelings. The fever was ok, never broke too high and it was short-lived for about a couple of hours, feeling my heart was not comfortable but bearable and I wouldn't get too tired.

I'm so glad it was temporary, and so sorry for your wife having this lingering on her, I do not wish it to anyone.

IQ is not concentration. In fact, IQ or intelligence in general does not have a single accepted definition†. You are not "stupider" because you have no patience to sit down to concentrate to do a silly test. Nor you are "smarter" because you found it so engaging you hyperfocused and did it in one sitting.

IQ tests are designed by people that want to create automatons easy to quantify and categorize.

† My definition of intelligence is "ability to solve novel problems." With this definition, an uncontacted tribesperson can be as intelligent as a Nobel prize winner. The difference is education, and the type of problems they're facing, which is just a matter of context.

I think I read that most ancient civilizations collapsed because of environmental factors. The environment changed, and they couldn't cope with it for some reason (lack of technology was probably a big part).

As for China, I don't think that one ever "collapsed". It withdrew, but I don't think you can call it a "collapse" the way many other ancient civilizations did. Even Rome is a bit hard to call a full collapse: it degraded over the course of centuries, and eventually Europe turned to feudalism. The Roman Empire itself split apart, with the eastern part (in Constantinople) continuing for another 1000 years after the western side fell apart.

I think civilizations like the Assyrians and Hittites are better examples of civilizations that truly "collapsed": there's basically nothing left of them today, except some ruins.

IQ as measured seems to be intended to be a "mental maturity index".

It's best administered to children to understand where they are relative to other children and makes little sense in adults.

That's why IQ is age dependent. A 12 year old with a 140 IQ should have the mental pattern matching recognition as a normal 14 year old with 100 IQ.

The standard deviation is based on the next year ups mean IQ and so on.

It doesn't necessarily measure intelligence, but in children it can be used as a proxy for intelligence since usually brain maturity is directly linked to intelligence.

the best sports players and best musicians I would also suppose were higher IQ on average than normal sports players (I suppose this term means professional athletes) and normal musicians (professional musicians)

In the musicians category I wouldn't be surprised if the best musicians were also smarter than the general population.

IQ doesn’t seem to be an ideal metric for macro level civilisation intelligence. A lot of what it optimises for is replaced by technology. If we’re measuring intelligence at that level I’d hope for something like theory of mind/spiral dynamics, testing how wide someone’s perspective is.

Is their world model limited to themselves, their family, their village, their country, their race, their world, their species, their system? Combined with their understanding of social dynamics at each level.

I think the average GenZ in the US is at beginning of global scale, which is great for acceptance of different cultures; but without understanding the social dynamics yet. Giving us “woke” because they understand different cultures have different contexts, this is good but incomplete. E.g. some cultures aren’t aligned with the entire species, like controlling women in a way that leads to bad outcomes as technology adds complexity to our social dynamics.

Measuring this perspective level would help us understand which cultural models work best in adapting with growth and are more likely to be sustainable post-scarcity.

The title is misleading, at least on the IQ claim. The underlying study was observational and did not claim causation.

Medical journals and their associated media summaries are awash with low-certainty studies that get de-nuanced and overhyped. These studies are relatively easy to do - not to denigrate the work put in by the original study authors (it’s not their fault the press sensationalize their work). But for strong causative claims you ideally would have blinded controlled randomized trials. Sometimes such trials are not feasible, but that doesn’t mean you get to claim causation anyway just because the work to prove it is too hard.

It's less misleading then you might think.

There are cases (enough to not be treated as just some random coincidence; with and without vaccination) where people after Covid had a sever reduction of cognitive abilities that they have problems filling out relatively simple forms. So we can clearly speak of a reduction of IQ.

And while there is a lot of research needed and a lot of open questions and already half a year (or so?) into the pandemic we did know from how we observed COVID affecting the brain that it likely will cause a reduction in cognitive abilities at least in some cases which matches the (very many) observations we had since then.

This also matches what we know from other older studies about other virus infections which have some similarity with covid, e.g. causing Neuroinflammation. So every thing we observe and do know about the underlying mechanics implies that there is very likely a causation. (Through we need more studies for Neuroinflammation.)

So scientist do need to research it more and do need to pin down the exact mechanisms this causes reduction of cognitive abilities in some cases to largely varying degrees and how much of it is a direct and a indirect e.g. psychological effect.

But for everyone else it best to assume that getting COVID might reduce IQ if they are unlucky. Because if you aren't a doctor, scientist or similar but just a random person who got COVID it kind doesn't matter if your IQ gets reduced by COVID directly or indirectly or just correlated due to some other factor you don't know about and in turn can't systematically avoid.

I do not think IQ tests are meant or designed to measure effects from illness. We do not say that IQ drops when you are sick with the flu and have high fever that makes it hard to think. IQ does not drop when you wake up groggy in the morning up until you drink coffee. I am not sure why people use IQ here instead of referring specifically to brain fog and other symptoms of post-COVID infection. IQ does not drop when you get sick and does not increase when you get treatment. If that is the case, then it is even worse measure than it is supposed to be, because it does not measure anything remotely stable.

At some level, IQ tests measure your ability to take IQ tests. So it would make sense that your measured IQ would go up when you're on ADHD meds, since those will obviously have an effect on your ability to take IQ tests.

Who says there’s even anything stable to measure?

If “intelligence” is just the degree/quality of someone’s brain function then your intelligence does drop when your brain function is impaired, and you would expect that to be picked up in an intelligence test.

Culturally we may want to imagine intelligence as something constant and innate to somebody’s soul, but in reality it’s innate to a fragile and fickle organ inside your skull.

Culturally we may want to imagine intelligence as something constant and innate to somebody’s soul, but in reality it’s innate to a fragile and fickle organ inside your skull.

Which is also my issue with IQ tests and the relationship of the tests and what they measure. But that changes nothing: IQ tests are not supposed to measure _that_ variability of when you get sick. Or you wake up. Or you are drunk. It makes no sense to use a psychometric test completely out of the context of which it was validated and meant to be used, because then the results are not interpretable. People with that kind of post-covid syndrom have an illness and experience cognitive deficits because of that, but using IQ to measure intelligence in that case when what you actually (want to) measure is brain fog is absurd. That should require a brain fog screening, not an IQ test.

But for everyone else it best to assume that getting COVID might reduce IQ if they are unlucky.

Why assume it if it's not proven yet? We had crazy assumptions on the way lightning worked, I'm glad we have empirical natural sciences now to counter these "wide spread assumptions".

Wrt covid and IQ. Say that during covid IQs measurably dropped: why says its not the WFH, the fear that was rampant or the mRNA vaccine that was massively injected? There for we need bigger studies, control groups, randomization. All of this is there for good reasons (and a lot of this was skipped in the development of mRNA vaccines for a bad reason: fear).

Seconding the sentiment here. Quibbling about "causal" being used in the title aside, we're building more observational evidence that there's negative cognitive effects associated with covid and long covid.

Zhao et al '24 [0] comes immediately to mind; operating on a radically different set of people and data sets from Al-Aly and the gang, they find substantial differences in simple reaction time between covid and no-covid groups.

It seems we're in a phase of the pandemic where denying long tail effects is going to become more prominent as concerning evidence continues to pile up. The name of the game is still to reduce your infection count as much as possible. Stay safe out there, share aerosols unprotected at your own peril.

That's why the most important element in science is replication - direct (repeating the same experiment) and indirect (refining the original experiment, or testing for the opposite result, or an alternative - here we could test reflexes instead of IQ).

They are also constantly defended.

Good, calibrated IQ tests measure something, and that something has a positive correlation with work efficiency in at least certain types of work.

That said, there are many types of IQ tests and some of them are in my opinion rather weird, for example anything where your score depends on your knowledge of English language or English history as I hear has traditionally been the case in US.

Around here it seems they try to make the tests as little dependent on language, history and even math as possible and the ones I have taken has largely been about:

- pattern matching (of these 6 squares with various patterns, which one doesn't fit in?)

- sequences (based on these 3 squares with patterns, which is the next one?)

- and that kind of stuff

These skills are things that are very real, very measurable and often linked to work throughput. Yes, I rarely visualize boxes in my head and rotate them and I rarely sift through through black and white squares with alternating patterns at work, but it seems the ability to do so is often linked to the ability to mentally single step code or spot patterns in bug reports.

It doesn't mean that you are good person if your score is high (or low) and it doesn't mean that you will be a good employee and not waste your time on HN.

The tests that work in measuring human behavior are fairly simply and very repeatable. Think Fitts's or Hick's Law, which involve hit testing and searching through an unsorted list. I can imagine pattern matching being fairly repeatable as well, but I'm not sure how it really relates to real problem solving. Then again, medical doctors are basically pattern matchers (and why they are fairly excited about AI assistance in...matching patterns).

Anyway, it seems obvious it's culture dependent. Given a person with usual western education and a person who's never dealt with shapes and abstract straight lines in their life - would you expect them to score similarly if they're both very intelligent people? These tests heavily rely on geometric puzzles which already make an assumption about education. The tricky question is how much does that affect differences you'd see between random people tested for comparison.

Viral persistence is one theory that may explain a subset of long covid and other postviral cases (mecfs example [1]). There's lots of theories including itaconate shunt [2] and metabolic trap [3], glutamate toxicity [4], cranio-cervical instability and infections causing breakdown of tendons [5], gut biome imbalances [6][7], endothelial damage, and others. I'm not sure what the most promising ones are but the search for biomarkers continues.

What we call long covid or mecfs or chronic lyme or fibromyalgia etc etc are all umbrella terms for symptom clusters so they lack some specificity and are likely multi-causal. There are many overlaps in LC and mecfs patient populations in studies (vs controls), so its likely a fair-to-significant amount of LC is actually what we call mecfs.

Much of the mystery and suffering of long covid would have been avoided if we'd invested anything in investigating these conditions pre-covid (mecfs has the least funding to disease burden and the worst quality of life of all major diseases), but the medical community generally didn't want to believe these diseases were real. Same thing happened with autoimmune conditions like lupus and MS before their mechanisms were discovered. All of these conditions predominately affect women.

The idea that there is a control arm of people who haven’t gotten Covid large enough to power a real control here is farcical. Again, a problem of self selection for people committed enough to maintain a large level of isolation for multiple years.

The relevant bit of transcript:

Faust: I just want to follow up on something you said a moment ago about where this virus can be found in tissues. Are you suggesting that long COVID is actually, the mechanism of that, is persistent live virus in humans?

Bertagnolli: We see evidence of persistent live virus in humans in various tissue reservoirs, including surrounding nerves, the brain, the GI [gastrointestinal] tract, to the lung.

Faust: OK. And you're saying this goes beyond the PCR's [polymerase chain reaction test] ability to get it in a regular swab so that we are missing chronic cases of SARS‑CoV‑2?

Bertagnolli: Correct. The virus can persist in tissues for months, perhaps even years.

Faust: OK. I think that's certainly one theory, but I'm not sure that that's settled. Is that fair? I mean, there's one thing between people who are autopsy, they died of viral sepsis, as opposed to people walking around. Is there a distinction there?

Bertagnolli: Our emerging data shows that the virus can persist into tissues in the long term, and I think that's really critical because it does help us think about possible ways to combat it, one being better antivirals. I think there's a lot of focus on developing new antivirals as a possible way of preventing long COVID, and the other might be more aggressive treatment with antiviral therapy upon initial diagnosis.

Faust: If that's the case, then it could be reactivated just like herpes is and shingles. Are we going to start seeing people get COVID not from infection, but from themselves in reactivation?

Bertagnolli: I don't believe I've seen or heard of any instance of that, and I don't think you can ever assume that one virus is going to act like another. Certainly every virus that we know of seems to have a different effect in the body long term.

Though, you would have to have enough people in this group, not be too rare. And it would help if there was already a large population that was IQ measured prior to Covid, and could be re-measured.

It seems unlikely that such a scenario exists.

My bet is that trolls in government, fake news and anti-scientific facts injected in vein 24/7/365, helped a lot to grease that piggy.

Accelerated brain decay with the last and current politics in the planet is basically guaranteed.

I had brain fog with COVID but it does get better with time. Still sometimes struggle to find the right word. There is also Alzheimer's in my family so that is something additional to worry about

2015 observational study suggests these results are not unique to Covid: ""Our research shows a correlation between hospitalisation due to infection and impaired cognition corresponding to an IQ score of 1.76 lower than the average. People with five or more hospital contacts with infections had an IQ score of 9.44 lower than the average. The study thus shows a clear dose-response relationship between the number of infections, and the effect on cognitive ability increased with the temporal proximity of the last infection and with the severity of the infection."

The symptoms of tingling in the extremities resemble what my wife experienced after her chemo when the treatment damaged her neurons' myelin sheath. This causes 'noisy' neuron signals to be transmitted (tingles, lack of sensation, etc.). If the same thing happened in the brain, I bet the noisy signals would lead to brain fogginess, forgetfulness, etc. Back then, she was taking omega-3 supplements and received shots of vitamin B12. After a year, it removed almost all the tingling, but some sensations never fully came back.

This is not medical advice (and check with your doctor beforehand), but it feels like taking vitamin B12 and omega-3 supplements should be a pretty low-risk bet to try to improve your situation if you're experiencing the long COVID symptoms described in the article.

I'm dismayed by the number of people who apparently don't subscribe to evidence-based medicine using proper statistical methodology and instead rely on anecdotal evidence whenever Covid comes up. It's very irrational, though some of this behavior can probably be explained by the extreme politicization of the topic in the US.

A reading of Oliver Sach's pop-sci books on encephalitis & PVS suggests we've actually been here before in the 19th and 20th century with cognitive and other effects down to post viral conditions. It's just another instance of something we probably know happens.

I think we still have yet to learn about how else COVID could have affected us

A Chinese researcher speculated this would be a major source of worldwide cognitive decline. Perhaps the Chinese knew something about the disease we don't leading to their extreme lockdowns.

I've noticed my memory and math skills getting worse as well. Can't say it's covid for sure though as there are other likely explanations too: getting fatter and out of shape, finishing uni and going out of practice, long-term sleep deprivation, etc.

Either way, if not covid, then I think at least the lockdowns did have an impact on my health and ability to stay fit.

The studies cited do not prove any causative association. They lack controls and other design elements that would account for misattribution and the impact of COVID-related psychosocial factors on observed symptoms.

In general, there is an extreme lack of rigor seen in claims about long COVID. The best evidence available suggests most cases of "long COVID" are misattribution:
