We know the symptoms of long Covid include things like memory problems and 'brain fog.' But one of the most rigorous examinations of the long-term cognitive impacts of severe Covid-19 infection has unveiled some troubling results. In a study comparing 46 severe Covid-19 patients, researchers from the University of Cambridge found the mental impacts of severe Covid six months later can be the equivalent to ageing 20 years - going from 50 to 70 years old - or losing 10 IQ points. Neuroscientist David Menon was senior author of the new paper, which was published in eClinical Medicine.
