The brains of people long-term infected with the new coronavirus are affected even two years after infection

About four years have passed since then. COVID-19 Appeared. Vaccines have greatly reduced the number of deaths associated with the disease, but many people who survive the infection still have to die. endure the symptoms of long.

According to personal testimony and research on the subject, COVID-19 may: Causes cognitive decline months after infection. Indeed, two studies showed that cognitive deficits may increase depending on disease severity at the time of initial infection. Another study in the UK revealed structural changes in the brains of patients.


In new research, Scientist at King’s College London Researchers investigated the impact of COVID-19 on cognitive skills such as working memory, motor control, attention and reasoning in 3,000 people.

Symptoms persist for months after infection

The Previously Conducted Studies on Long-Term Novel Coronavirus Presented some drawbacks Since they were running in the meantime, relatively short period and just get involved Small hospital cohort. Furthermore, the study did not compare COVID-19 positive cases with negative controls. Nor has it been demonstrated whether long-term COVID-19 recovery leads to improved cognitive performance.

In a new study, researchers sought to discover that Solutions to these problems. In 2021 and in 2022 he was given two online cognitive tests. Participants were recruited through an app launched in the UK in 2020. Research on the symptoms of the novel coronavirus.

The second test, nine months after the first, gave little idea of ​​the score. no improvement. As of this second test of his, for most people, Two years have passed since the first infection.

about fully recovered patient Considering the infection status of the new coronavirus infection, their condition was similar Dear participants never had coronavirus.

he pointed out Importance of follow-up People whose brain function has been most affected by COVID-19. this is, Control the progression of cognitive symptoms and provide better treatment for recovery.

teacher Claire StevesCo-author of the study, he added that more research is still needed to better understand the impact of COVID-19 on some people.
