Good news on Covid and your brain

Results: All six cognitive tests, measured before January 1, 2020, are significant predictors of infection status during the pandemic. The two subjective cognition measures show no significant association with infection. We replicate earlier cross-sectional findings of a negative association between COVID-19 infection and subsequent cognition. However, once accounting for baseline cognition, no significant associations are found for either the tests or the subjective measures. For three of the six cognitive tests the effects change signs.

Conclusions and relevance: We find no evidence for a negative association between COVID-19 infection and subsequent measures of cognitive functioning. The associations found in earlier studies may at least partly reflect reverse causation.
