From the article:
“…two new studies published in the New England Journal of Medicine shed further light on the profound toll of COVID-19 on cognitive health.” And in other studies cases “with mild to moderate COVID-19 showed significant prolonged inflammation of the brain and changes that are commensurate with seven years of brain aging.”
IQ is sort of bullshit, but it’s a measurement.
Equating IQ to overall intelligence is fruitless. It’s like asking the weather and only taking the temperature.
As a psychologist, high IQ is whatever, but low IQ is good in attempting to understand some individual’s behaviors or even classify kids into special ed classes for a cognitive learning deficiency.
Did they ask the exact same questions as before? If they did, it would probably skew the results. If they didn’t, it would also probably skew the results.
If they ask the SAME question and you score still goes DOWN I’m gonna go ahead and call that “a bad sign”.
