Several persons have reported losing their sense of taste and smell and experiencing "brain fog" due to COVID-19.

It is now connected to face blindness, also known as prosopagnosia, the inability to distinguish faces, according to recent research published in Cortex.

Self-report survey data from 54 people with lengthy COVID revealed that the majority of people reported decreased visual recognition and navigational skills, according to researchers.

Moreover, COVID-19 can cause significant and focused cognitive impairments comparable to deficits seen after brain trauma, and it appears that patients with lengthy COVID frequently experience high-level visual impairments.

According to a different study, more than 1% of people have trouble recognizing faces. Some people struggle to keep up because of how similar the performers look in TV series. And the syndrome can make people uncomfortable in social settings. In severe circumstances, those with the illness lose their ability to recognize themselves.

In March 2020, a 28-year-old woman was diagnosed with COVID-19, according to the researchers. When she first visited her family following covid, she could not identify her father because she had not fully recovered. She also experiences migraines, fatigue, and other typical COVID side effects, such as difficulty in concentrating.

Each side of the brain has six areas involved in the formation of facial recognition, and damage to any one of them, especially on the right side, might impair the ability to recognize faces.
