COVID-19 causes "chronic" cognitive deficits equivalent to brain aging 10 years

A study of more than 84,000 people in the UK found that the virus left even those deemed recovered with “chronic cognitive consequences” that it compared to dropping 8.5 IQ points.

“People who had recovered, including those no longer reporting symptoms, exhibited significant cognitive deficits,” the study published on MedRxiv said.

“The deficits were broad, affecting multiple cognitive domains,” the researchers warned in the study, which has yet to be peer-reviewed.
