Rare case of face blindness following COVID-19 infection reported
USA: Results from a case study of a 28-year-old woman named Annie indicate that COVID-19 can produce severe and selective neuropsychological impairment like deficits following brain damage. It appears that high-level visual impairments are common in people with long COVID.
Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), 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.
Marie-Luise Kieseler and Brad Duchaine from Dartmouth College in Hanover, NH, USA, and colleagues, in their study published in the journal Cortex, provide the first report of prosopagnosia after symptoms consistent with COVID-19.
In their 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 PASC/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.
