Cognition and memory in people who had and hadn’t had Covid-19 in a large community sample, REACT Long COVID

The REACT team at Imperial College London have carried out an observational study looking at measures of cognitive performance in people who had had Covid (mild or severe, and resolved or persistent) and people who had not had Covid.

Cognitive performance was measured once (using an online assessment platform), and the results compared in those who had and hadn’t had Covid – this is not a measure of change in cognitive performance in individual people.

The study was published in the New England Journal of Medicine.  Journalists came to this briefing to hear about the study from the authors and to ask their questions.


Speakers included:

Prof Paul Elliott, Chair in Epidemiology and Public Health Medicine, and Director of the REACT programme, Imperial College London

Prof Adam Hampshire, Professor in Restorative Neurosciences, Imperial College London


This SMC Briefing was accompanied by an SMC Roundup of comments.
