Long COVID, or post-acute sequelae of SARS-CoV-2 infection is characterized by several symptoms that resurface, begin, or persist even after 12 weeks of the initial COVID-19 infection. These symptoms include psychological problems comprising long-lasting memory, loss of smell and taste, psychosis, and language impairments that substantially impair everyday functioning. However, no persisting and selective visual perception deficits have been reported.
In the current study, the investigators reported that COVID-19 could sometimes cause severe selective impairments like prosopagnosia and well-known broad impairments. Survey data collected from individuals with long COVID also demonstrated that cognitive and perceptual deficits following COVID-19 were present in a substantial proportion of the respondents, though none report having acquired prosopagnosia.
