According to a study published Tuesday, COVID-19 has an impact on brain function. In the worst case, cognitive deterioration was equivalent to 10 years of brain aging. The study, which has not yet been reviewed, was conducted on 84,000 people by Adam Hampshire, a physician at Imperial College London.
According to this study, coronavirus is associated with cognitive deficits in the months following disease transmission.
“Our analysis confirms the view that Covid-19 has chronic cognitive implications. People who have recovered and no longer have symptoms show significant cognitive deficits.” – Researchers write.
Cognitive tests measure how well the brain performs various tasks (memorizing words, solving puzzles, etc.). Such tests are widely used to assess the cognitive abilities of the brain in diseases such as Alzheimer’s disease.
Cognitive deficits were particularly evident in people who were hospitalized and, in the worst case, ranged in age from 10 to 70 years, equivalent to 10 years of aging.
However, scientists who have not been directly involved in this study say that the results of the study should be treated with caution.
“Patients’ cognitive functioning was not known before coronavirus transmission and these results do not indicate a long-term condition; any impact on cognition may be short-term.” – Says Joanna Vardlow, Professor of Applied Neuroimaging Technologies at the University of Edinburgh.
Derek Hill, a professor at University College London, points out that the findings of the study may not be completely reliable because the researchers did not compare scores. “Overall, this is an interesting but insufficient study of the effects of COVID on the brain.” Says Hill.
