Cognitive sequelae of COVID-19 including memory and concentration difficulties have been observed in 40-65% of persons who have been hospitalised with COVID-19 and 27-50% of non-hospitalised individuals. The cognitive impairments are associated with reduced work function and quality of life. This review recommends systematic cognition screening at long-COVID clinics using brief and feasible objective cognitive screeners, such as the Screen for Cognitive Impairment in Psychiatry (SCIP) and Trail Making Test B or similar tests with sensitivity to cognitive impairment in young populations.
