Coronavirus could age the brain by 10 years or cause IQ to fall

Coronavirus survivors may be at risk of lasting cognitive damage, according to a study that found that in the worst cases the infection can cause mental decline equivalent to an 8.5-point fall in IQ or the brain ageing ten years.
Research involving 84,285 people who had recovered from confirmed or suspected Covid-19 found that damage to the brain had happened to varying extents, depending upon the severity of the infection.
