An analysis of people who were hospitalised with covid-19 in the first wave of the pandemic has revealed that the ongoing decline in their cognitive abilities is the equivalent to losing 10 IQ points
The cognitive abilities of people who were hospitalised with covid-19 during the first wave of the pandemic remain lower than expected, even years later, and there is some evidence that this is forcing them to change jobs.
“What we found is that the average cognitive deficit was equivalent to 10 IQ points, based on what would be expected for their age, et cetera,” says Maxime Taquet at the University of Oxford.
The tag line on this with regards to IQ is very misleading. Setting aside that IQ is a terrible form of measurement and no weight should be given to it, the study actually reveals that measured IQ is unchanged. They measured after discharge, and then several years later with no change. With no pre-covid measurement, this is a more than useless bit of data.
Depression and anxiety are increased, but so did that of the general population. So hard to tie any of that to COVID or long COVID.
