This is true.
Obviously it's just one study and more research needs to be done, but it does suggest that long term side effects can be present in those "fully recovered" from COVID. This is bad news.
IQ is an
exceedingly stable personality trait over a person's lifespan. It is a trait that
very seldom changes short of an individual receiving blunt trauma to the head - brain damage, basically.
Very few things are known to change IQ once a person is born, aside from breastfeeding, as one example I can name - and probably the only one I can think of, under North American conditions.
In Africa, the Flynn Effect is an example of IQ "improving" - but that involves Africans literally starving to death, improving their IQ scores once those extreme deleterious conditions are removed.
There are many African ethnicities that have average IQ scores around 70, who would have an IQ averages closer to 80, if they were raised under North American conditions, or if conditions improve in their African nations, potentially as a result of development of the region decreasing the total number of people living on under $2 USD per day, which I believe is the current global standard to measure extreme poverty [what used to be $1 USD per day around 25 years ago].
I think Israel would be a good example to see if this study holds, since Jews have the most IQ to lose, so as a "percentage" of IQ loss, you'd see a clearer picture.
But I don't know...I've heard of this "brain fog" from "long covid", but has any of this been established scientifically yet in the literature?
I've always assumed it to be more propaganda - since the mass deaths didn't come [the global population went UP 150 MILLION since this pandemic began

], I figured this was just more reaching for future negative effects, since it's obvious by now that nobody is dying who wasn't already dying, or was a fat cheeseburger eating piece of shit, or both.
Out of curiosity, OAK:
How many people personally do you know who died of COVID who wasn't old as fuck, or wasn't a fat cheeseburger eating piece of shit who eats cheeseburgers, and is fat?
I literally no no one.
Where are all the ambulances WAILING?
Where are all the funeral processions?
Am I supposed to go another 200+ days with the gym closures because some fat disgusting stinking girls who eat cheeseburgers and are fat with cancer and ridden with diabetes get a virus that takes 16 months off the 30 months they had left to live?
Who gives a fuck? We - in Canada - have spent over $800 BILLION on this so far. We are borrowing $500 MILLION DAILY [from who???] to prevent people from dying basically one year later. Think about how many lives could have been saved with that money.
