D’après les scientifiques de l’Université de Cambridge et de l’Imperial College de Londres, dont les travaux ont été publiés dans la revue eClinicalMedicine de The Lancet, les formes graves du Covid-19 entraîneraient des troubles cognitifs similaires à 20 ans de vieillissement, entre 50 et 70 ans. Soit l’équivalent, selon l’Imperial College, d’une perte de dix points de quotient intellectuel (QI).
Multivariate profile and acute-phase correlates of cognitive deficits in a COVID-19 hospitalised cohort

On average, the scale of deficits was most similar to that observed in normal cognitive decline between the ages of 50–70; however, when examined in more detail the pattern of cognitive deficits was most pronounced for different tasks than either age-related decline or the dementia group. These more detailed results highlight the potential value of cross comparing multivariate profile of COVID-19 cognitive deficits to a wider variety of populations in order to identify potential similarities to other neurological conditions. Future work should also expand the repertoire of disorders, especially populations who have recovered from other critical illnesses, and cross relate these detailed cognitive profiles to imaging and blood biomarker measures of neuropathology and tracking recovery and decline trajectories over a longer temporal scale.
In summary, severe COVID-19 illness is associated with significant objectively measurable cognitive deficits that persist into the chronic phase. The scale of the deficits correlates with clinical severity during the acute phase as opposed to mental health status at the time of assessment, shows at best a slow recovery trajectory and the multivariate profile of deficits is consistent with higher cognitive dysfunction as opposed to accelerated ageing or dementia.
