Brain changes after COVID-19 - how concerned should we be?

Stéphane Kremer et al. Nat Rev Neurol. 2022 Jun.

Abstract

Analysis of brain images taken before and after infection with SARS-CoV-2 suggests that even mild COVID-19 is associated with brain structure alterations and cognitive impairment. However, the clinical implications for individuals are unclear and further studies are needed to assess the generalizability of the findings and whether the effects are long-lasting.
