Abstract: Objective To review the relationship between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and cognitive dysfunction and the mechanism of cognitive dysfunction in post-COVID-19 syndrome. Methods CNKI and PubMed databases were searched to collect relevant research reports on cognitive dysfunction after SARS-CoV-2 infection by traditional Chinese medicine (TCM) and western medicine from January 1, 2020 to October 30, 2023. Results Cognitive dysfunction might occur after SARS-CoV-2 infection, which might be related to the neuroaggressive, neurotropic, and neurovirulent nature of the SARS-CoV-2 virus, or to factors such as post-infection-mediated hyperinflammation, serotonin levels, and viral metastasis. It was also found that some TCM monomers had the effect of improving cognitive dysfunction after SARS-CoV-2 infection. Conclusion Cognitive dysfunction may occur for a short time or for a long time after SARS-CoV-2 infection, and its mechanism needs to be further verified by clinical and basic research.
