摘要
Previous studies have reported that nearly one-fourth of coronavirus disease 2019(COVID-19)survivors suf-fer from persistent cognitive impairment,including impaired memory,attention,concentration,executive function,and speed of information processing[1-3].Omicron is the latest severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)variant of concern(VOC)reported in November 2021[4],characterized by a large number of spike mutations,great transmissibility in the presence of other VOCs,and an ability to spread in populations with high level of immunity[4].However,whether patients infected with Omicron COVID-19 variant develop cognitive impairment,similar to those infected with other VOCs,remains unclear.
