Glymphatics and brain fog – the post-COVID-19 phenomenon

Abstract

Since the COVID-19 pandemic and now since the vaccination has emerged as a success, many new signs and symptoms are being observed. Although most people with COVID-19 get better within weeks of illness, there is a wide range of new, relapsing, or ongoing health problems that many people may experience for weeks or more after being infected with the virus that causes COVID-19. Even people who did not have symptoms when they were infected can have post-COVID conditions. The most commonly reported of these symptoms are related to the neurological system, including brain fog, fatigue, anxiety, anosmia, and depression. The role of glymphatics in post-COVID brain fog is a widely studied phenomenon. This review will also explore the possible etio-pathogenesis of brain fog in post-COVID-19 patients.
