Intelligence quotient falls after Covid-19, according to study

Some of the Covid-19 patients have what they call brain fog which they see as a long term consequence. Researchers call this cognitive limitations, who are now using the copious amounts of data to test whether Sars-CoV-2 infection actually affects these abilities.

British researchers have investigated the effects of Sars-CoV-2 infection on a condition known as cognitive abilities. Scientists at Imperial College London took a total of 81,337 people with an average age of 46.75 years for an IQ test between January and December 2020. Then they evaluated the data. Adam Hampshire’s team found that 12,689 respondents who had previously been infected with Sars-CoV-2 and had Covid-19 with very different severity, performed significantly worse in this test than those who were not infected with the coronavirus before the test. A total of 275 people got tested before and after the Sars CoV-2 infection.

According to the results of the study, which were published in “The Lancet” magazine, found major differences between infected and non-infected in tasks that had to think logically, plan and solve problems. According to the researchers, the greatest reduction was found in those who had to be treated in intensive care due to Kovid-19 and were supported by ventilators.

seven points less

In these patients, the IQ quotient was on average seven points lower than in the control group. The researchers clarified that this reduction corresponds to approximately ten years of brain aging. Factors such as age, gender, education level, income and previous medical disorders were taken into account by the researchers in the analysis.

The research results not only agree with other study results on the long-term effects of COVID-19, they also match statements from COVID-19 patients who reported difficulty finding the right words, difficulty concentrating, and “brain fog”. report long-term effects. “. Further investigation is urgently needed to understand how Covid symptoms last for so long, how long they last and whether they can be treated, stress the researchers. find that critical word too: “I think it’s also fair to say that the people we’ve analyzed this kind of data are a little nervous about making the decision to let the UK pandemic run its course, Hampshire says PsyPost.
