Cognitive decline after Covid: the brain will age by 20 years, according to British researchers

The Covid virus not only affects the bodily organs, but it will also age brain and cognitive functions by twenty years according to a study published in early May in the scientific journal eClinicalMedicine.

A study published in early May in the journal Clinical Medicine It reveals the harmful effects of Covid on the brains of hospitalized patients. The researchers from the University of Cambridge, who conducted the study, observed cognitive impairment similar to brain aging for several years. British scientists have observed a persistent decline in cognitive functions in these people with long-term COVID-19. “Only one in three participants felt fully recovered after a year of Covid,” explains Dr. Rachel Evans, who is responsible for the post-hospital study of Covid.

Fewer symptoms with vaccinations

David Menon, lead author of the study, explains in an interview with guardian. If you have a vaccine and all your booster shots, the disease will be less stressful and all of your symptoms will be reduced.”

Losing 10 IQ points

Two groups of patients (one hospitalized with Covid, the other not developing the disease) underwent the same cognitive tests. Inpatient outcomes are lower. The speed of information processing is particularly affected. “Cognition loss is similar to what occurs between the ages of 50 and 70” summarizes the site c . news. This corresponds to a loss of ten IQ points.

David Menon asserts: “These experiments will allow us to understand the underlying mechanisms and produce effective treatments to prevent and treat this phenomenon later.”
