Scientists have described a case of face blindness in a 28-year-old woman after contracting COVID-19.

Writing in Cortex, researchers highlighted that the patient had normal face recognition before she became infected with COVID-19 in March 2020.

She noticed that when her COVID-19 symptoms relapsed, she would have difficulties recognising faces – including members of her own family.

“On two tests of familiar face recognition and two tests of unfamiliar face recognition, Annie showed clear impairments,” the researchers highlighted.

The patient also experienced difficulties with navigation – a deficit that often co-occurs with face blindness.

A survey of 54 respondents with long COVID found that the majority reported reductions in visual recognition and navigation abilities.

Lead author, Marie-Luise Kieseler, of Dartmouth department of psychological and brain sciences, highlighted that most respondents with long COVID reported a drop in cognitive and perceptual abilities.

“It was not just a small concentration of really impaired cases but a broad majority of people in the long COVID group reported noticeable difficulties doing things that they were able to do before contracting COVID-19 without any problems,” she said.
