Scientists have confirmed this information after examining data from those who have had coronavirus. All of them passed intelligence tests, as well as polls about COVID-19.
As part of the study, scientists compared the results of people of the same age, race, gender, income, education, and a number of other similar criteria. This helped to assess the impact of the disease on cognitive ability.
“People who recovered from COVID-19, including those who no longer reported symptoms, had significant cognitive impairment compared to controls when controlled for age, gender, education level, income, race, ethnicity, previous medical disorder, fatigue , depression and anxiety, “- said in the message.
Experts have revealed that COVID-19 really impairs intelligence, and the more severely people get sick, the stronger the negative effect. For those who were connected to ventilators, the decrease in brain performance was equivalent to seven IQ points.
At the same time, even a stroke affects cognitive abilities less: the damage to the brain from it is comparable to the damage from COVID in an average form.
According to scientists, the ability to abstract logical reasoning, planning and concentration suffers most from the coronavirus.
At the same time, after the patient recovers, his cognitive abilities are not restored to the previous level.
In total, more than 80 thousand people took part in the experiments, 12 thousand of whom had had coronavirus.
