Is self-report brain fog after mild COVID-19 truly induced by COVID-19 infection? A longitudinal fNIRS study
Mild COVID-19 infection does not lead to apparent cognitive deficits or depression, although brain activation and global efficiency are reduced post-COVID-19. Brain fog is likely to result from depression rather than cognitive deficits induced by COVID-19. People should pay attention to their psychological states during COVID-19 pandemic.
