God was not with Daniel in the lionā€™s den.

Looks like he was just on high flow nasal cannula, so not that close to death

EClinicalMedicine, published by The Lancet, have a study which was run by Imperial College under the auspices of BBC Horizonā€™s ā€œGreat British Intelligence Testā€.

Sample was over 80,000 people. They demonstrate cognitive deficits in people who have had COVID. Deficits increase in a symptom-dependent manner and are also greater for lab-confirmed COVID vs ā€œI think I had COVIDā€.

A followup questionnaire had no cognitive testing, so they donā€™t have longitudinal data, but they were able to show that people who got COVID in the interim between the two questionnaires did not differ on baseline cognitive profile. That makes it unlikely that the deficits uncovered represent a pre-existing deficit in people who get COVID.

Heā€™s not bad, actually. South Australia wants to become net 100% renewables, thatā€™s bipartisan policy, and the Marshall government are aiming to cut emissions 50% by 2030.

Australiaā€™s problems with climate change are digging fossil fuels up and shipping them to China, which is a federal issue. There are no coal mines in SA - the last one shut in 2015 for economic reasons - so the question doesnā€™t really arise.

So from a quick look at this they are showing drops in people who get sick? doubt thatā€™s too specific to covid

Good news for those that are already so cognitive defective that they canā€™t convince themselves to get the vaccine. Not much room to fall in the cognitive scale.

Deficits were much greater in people with lab-confirmed COVID (section B in the graph above shows the standard deviation difference in effect size of lab-confirmed vs non-confirmed, for the same symptom profile). They even say this in the discussion:

Conversely, the scale of deficits in cases who were not put on a ventilator, particularly those who remained at home, was unexpected given the limited literature on other respiratory illnesses such as cold. Although these deficits were on average of small scale for those who remained at home, they were more substantial for people who had received positive confirmation of COVID-19 infection. A corollary of this is that cognitive deficits associated with other respiratory illnesses that are mistakenly self-diagnosed as COVID-19 are likely to be negligible.

Itā€™s already known that stays in intensive care cause drops in cognitive scores; thereā€™s discussion of that in the paper as well.

No itā€™s not. Itā€™s literally hundredths of a standard deviation from the bottom end of the error bar.

Itā€™s the equivalent of 2 IQ points mean to mean and less than that from the error bar. Itā€™s a lot of things, large is not one of them. Iā€™ll look at it later, but I donā€™t see anything too interesting in that data at first glance.

Well I said ā€œmuch greaterā€, in relative terms. Like in the ā€œwithout respiratory symptomsā€ cohort the effect size is -0.04 SD, but the difference between lab-confirmed and unconfirmed within that cohort is -0.18 SD. But no, thatā€™s still not a huge effect size in absolute terms.

Itā€™s also easily explained by one group being sick and the other being hypochondriacs. I just donā€™t see the significance in the paper as presented. Suppose itā€™s a shitton of work to show people that it sucks to get sick in ways you might not have thought of.

The reaction to this will be interesting.

Iā€™m at a poker table with an older guy who said that he raised his kids unvaccinated but chose to get the COVID vaccine for himself.

Has Florida stopped reporting daily case numbers? They show up blank on Worldometer each of the last two days.

The findings suggest that the SARS-CoV-2 virus that causes COVID-19 can produce substantial reductions in cognitive ability

I can think of an alternative interpretation of the results.

they started that like 6 weeks ago.
