New research published in the New England Journal of Medicine reveals that Long COVID could potentially trigger declines in thinking and cognitive abilities. The study involved cognitive testing on 113,000 people in England, showing that those with Long COVID scored lower on IQ tests compared to those who had never been infected. Even those who did not have persistent symptoms after COVID scored slightly lower. However, the differences in scores were small, indicating that COVID does not necessarily cause profound deficits in thinking and memory. The study also suggests that if Long COVID symptoms resolve, related thinking impairments may improve.
