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

Scientists continue to learn about the Covid-19 virus and its long-term consequences. 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-19, the scientists keep discovering new elements about the virus. The latter seems to be responsible for many long term sequelae on the human body and brain, and could in particular be responsible for a premature aging close to the brain 20 years as well as a lower intelligence quotient.

According to a study published in the journal EClinicalMedicinepeople hospitalized because of the virus would have thinking difficulties. Cambridge University researchers noticed a persistent cognitive decline in some patients, using tests, which they compared with people who had not contracted Covid. The information processing speed so seems to be slower for the sick, with effects that last at least six months later.

Furthermore, a loss of ten IQ points has been observed, a cognitive loss comparable to that which occurs between the ages of 50 and 70. 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 understand the underlying mechanisms and produce effective treatments to prevent this phenomenon and treat it later.“.
