Covid-19 Infections and Cognitive Function
A study by Bas Weerman et al. explored COVID-19 infections' link to cognitive function using UAS data. Pre-pandemic cognitive tests predicted infection status, but subjective cognition did not. No negative association found post-baseline cognition, hinting at reverse causation influence.

The study conducted by Bas Weerman and colleagues aimed to investigate the association between COVID-19 infections and cognitive function. Using data from the Understanding America Study (UAS) with approximately 9,600 respondents, the researchers analyzed cognitive measures collected before and during the pandemic. Results showed that while cognitive tests conducted before January 1, 2020, were significant predictors of infection status during the pandemic, subjective cognition measures did not show a significant association with infection. The study found no evidence supporting a negative link between COVID-19 infection and subsequent cognitive functioning once baseline cognition was considered, suggesting that earlier associations might have been influenced by reverse causation. The findings contribute to understanding the long-term health effects of COVID-19 infections on cognitive function.
