Covid: brain aging and loss of IQ, new sequelae of the virus?

Scientists continue to learn about the Covid-virus 19 and its long-term sequelae. According to a study, the patients could present a premature aging of the brain as well as a loss of IQ.

More than two years after the appearance of Covid-20, scientists are constantly discovering new information about the virus. The latter seems to be responsible for numerous long-term sequelae on the human body and brain, and could in particular be responsible for a premature aging of the brain by almost 20 years as well as a lower intelligence quotient.

According to a study published in the journal EClinicalMedicine, people hospitalized because of the virus would have difficulties thinking. Researchers at the University of Cambridge noticed a persistent cognitive decline in some patients, using tests, which they compared with people who did not not having contracted the Covid. The speed of information processing thus seems to be slower for patients, with effects which last at least six months afterwards.

Furthermore, a loss of ten intelligence quotient points was observed, a cognitive loss comparable to that which occurs between 50 and 37 years. For David Menon, who conducted the study, the latter marks a turning point in the search for the sequelae of Covid, because " these trials will allow us to grasp the underlying mechanisms and produce effective treatments to prevent this phenomenon and treat it later".
