The cognitive impairment caused by severe Covid-19 is comparable with the decline that takes place between the ages of 50 and 70, according to a recent study by Cambridge university and Imperial College London.
Researchers said the degeneration was equivalent to losing 10 IQ points. The findings, published earlier this month, were the latest in a series of studies that suggest Covid-19 has an impact on the brain.
The lasting impact of Covid-19 on the millions who have contracted it is still being assessed more than two years into the pandemic, with few areas of uncertainty as urgent and unsettling as the potentially enduring effects on the brain.
