While its primary function is to transport cholesterol, it also regulates metabolism, aggregation, and deposition of amyloid-β (Aβ) in the brain. The disruption in the generation and removal of Aβ in the brain is the primary cause of memory and cognitive loss and thus plays a significant role in the development of AD. In several prior genetic investigations, the APOE4 allele has been linked to higher susceptibility to severe acute respiratory syndrome (SARSCoV- 2) infection and COVID-19 mortality. However, information on the involvement of APOE4 in the underlying pathology and clinical symptoms is limited. Due to the high infection and mortality rate of COVID-19 in AD individuals, challenges have been identified in the management of AD patients during the COVID-19 pandemic. In order to provide evidence-based, more effective healthcare, it is critical to identify underlying concerns and, preferably, biomarkers. The risk variant APOE4 imparts enhanced infectivity by the underlying coronavirus SARS-CoV-2 at a cellular level, genetic level, and route level.
