People in hospital for one severe form of Covid-19 They will take a risk Lose up to 10 IQ points In the six months following infection, an intellectual loss equals the cognitive decline experienced on average over a span of 50 to 70 years.

The discovery of a possible relationship between Covid-19 and persistent cognitive deficits was contained in a study conducted by a team of scientists from the University of Cambridge and Imperial College published in a journal associated with “The Lancet” and the results of which were reported by “Corriere della Sera”.

At present, it is not clear to what extent the cognitive impairments discovered by British researchers are permanent.

How was the study conducted?

The researchers evaluated the results of several cognitive tests performed 6 months after injury 46 patients admitted to intensive care for Covid-19Compare it with the results of cognitive tests conducted on one of them Control over the population of 66 thousand people.

All patients participating in the study were admitted to Addenbrooke’s Hospital between March and July 2020. Sixteen of them underwent controlled mechanical ventilation.

The platform was used to conduct the tests cognitron, which measures various aspects of mental faculties such as, for example, memory, attention, and thinking.

In those who have been cured of Covid-19, which on Tuesday 3 May 153 killed in Italy, many have been found Cognitive deficit, such as reducing the speed of information processing and decreasing language comprehension skills. The effects were stronger for those who had to resort to mechanical ventilation.

The researchers estimated that the extent of the average cognitive loss was similar to that of more than 20 years, between the ages of 50 and 70, and equated to a loss of 10 IQ points.

Adam Hampshire of Imperial College London, the first author of the study, confirmed in some of the data reported by the newspaper “Corriere della Sera”: “In England alone 40,000 people have been hospitalized in intensive care due to Covid, and this means that cognitive deficits after Covid can be It affects a large number of people around the world.”
