Coronavirus infection has been associated with reduced mental capacity

Scientists from King's College London, the University of Cambridge (UK) and the University of Chicago (USA) conducted a study involving more than 80,000 people with coronavirus and found that the disease had impaired their cognitive abilities as if they had aged 10 years. Mostly, their memory and intellectual abilities were affected. The results have been published by the medRxiv digital scientific library.

The SARS-CoV-2 coronavirus exhibits several symptoms, including loss of smell. Some scientists believe that the virus can use the olfactory receptors in the nose as a kind of "gateway" through which it enters the brain, spreads throughout the nervous system and thus disrupts normal cell function. This pathway is being studied at the moment.

In this study, experts found that coronavirus survivers have decreased mental ability and memory problems. They analyzed the results of cognitive tests in 84,285 British citizens. All participants were either hospitalized with severe COVID-19 or suffered a mild form of infection. Approximately 65% of them were less able to cope with mental tasks than the rest of the British population (particularly affecting their understanding of text and the meaning of words). It was as if their brains had aged 10 years, scientists say.

They intend to conduct further research to find out what such results might be associated with.
