Not sure why you’re getting downvoted - here’s a page about post-intensive care syndrome, on the website of the society for critical care medicine, that’s concordant with what you said: https://www.sccm.org/MyICUCare/THRIVE/Post-intensive-Care-Sy...

Possibly for what HN calls "middlebrow dismissal" - wandering in and dismissing the article with blindingly obvious issues ("probably caused by the sedatives, immobilization" etc) as if professional medical researchers wouldn't have thought of them. They plainly need a clear-eyed HN reader on staff to help them.

That term is very apt. I found this blog post about it, which I think really hits the nail on the head, too:

http://www.byrnehobart.com/blog/why-are-middlebrow-dismissal...

> Paul Graham, News.YC’s moderator emeritus, says that “The defining quality of the middlebrow dismissal is that it’s a cache dump of the writer’s prejudices…” This probably explains why they’re so common. It’s natural to see any news story as confirmation of your existing prejudices—but it’s easy to read confirmation where it’s not there. So it’s easy to see Groupon or Zynga as a “failure” for being worth merely a couple billion dollars when they were once worth ten billion plus apiece. (You could get pretty rich failing like that a few times.)

> But the real driver is not just that it’s easy to misread a story as confirming your beliefs. It’s that the alternative is to read a story and realize you were wrong. And since a middlebrow dismissal is a dismissal of something, it’s generally a dismissal of something that disagrees with the reader’s bias.

“not in substantial” :)

This is a very English way of expressing oneself.

I also used to find this disturbing, but the way I have explained this to myself is --

Insignificant 75%

Of course for each individual situation the numbers vary, and I use them simply to demonstrate that it's a matter of degrees, and not as binary as you may expect a typical "not" to be.

It is the only double negative I have come to find useful.

A quick Google search reveals that cognitive deficit seems to be a common consequence in any critically ill patient, not just Covid-19

This study[1] of just one example:

Cognitive dysfunction is an important long-term complication of critical illness associated with reduced quality of life, increase in healthcare costs, and institutionalization

And the numbers are certainly high:

Cognitive impairment was identified in 206 (49.9%) patients, 120 (29.1%) patients had mild or moderate cognitive impairment, and 86 (20%) patients had severe cognitive dysfunction.

It’s equally as surprising to me the suggestion that the average decline in IQ from a stroke would be only 6 points or so.

Varies a lot. I get a lot of minor strokes if I skip blood thinners for a week or so. At peak I’m a highly effective programmer. If I’ve had one recently, a “for loop” is a challenging concept. After a few days to weeks I’ll be back to near normal. Some symptoms last longer. Highly active Factor 5 Leiden, so I clot like crazy.

That sounds incredibly difficult. You must be a very strong and intelligent person.

This is perhaps impossible to test (which shows the fundamental weakness of social science) but I think it's nonetheless relevant: studies like this don't factor in overall societal attitude. I can't be the only one that has felt tired, depressed, and just plain bewildered over the past six months. The pessimistic doomsday mentality affects everyone, even if you don't actually get the virus. If I took an IQ test toda…

They are comparing test results of people who reported having a positive covid-19 test vs those that reported no positive test or symptoms. The timing of the study should not be a factor.

Good point. Thanks for the info.

Causation !== correlation. An alternative explanation is those more likely to catch COVID-19 are more likely to be a cohort with lower IQ to begin with (e.g. have lower skilled jobs that put them in harms way etc.). Without a before and after IQ test of biologically confirmed COVID-19 patients this is junk.

Sure as you say critical illness with long term medical effects is known to have this impact. The difference is that, as the abstract points out, substantial cognitive impairment in Covid patients was found even in people who displayed mild symptoms and were never critically ill.
