The Pandemic Appears to Have Accelerated Brain Aging, Even in People Who Never Got Covid

More than five After the beginning of it Covid-19 worldwideWe are not yet the virus, but the influence of chronic stress, isolation, damage and epidemic that uncertainty is discovering the impact of chronic duration. A new scientific study published this month CommunicationIt has revealed that the epidemic is never infected, but people can accelerate the growth of the brain.

Researchers at the University of Nottingham in the UK have analyzed the captive brain images before and after the health crisis began. Scientists have discovered that the brains of those who lived through the epidemic were seen faster than their time, whose brains were only scanned before March 2021.

“The most surprised me that people who were not even Covid showed significant growth at the aging rate of the brain,” said Ali-Reza Mohammad-Nizad of this study Statement On the university website. “It really shows how much the epidemic itself, from isolation to uncertainty, everything can affect the health of our brain.”

Has used longitudinal data from the team UK BiobankA huge datasate that collects biological information from about half a million people for a long time and has an MRI scan of about one thousand adults. Some of these people received two scans before the epidemic (control group), while others were in jail and one before and after health restrictions in response to the viral outbreak (“epidemic” group).

“The MRI data of the long -acquired longitude of the UK Biobank has given a rare window to monitor how the brain can affect the brain,” Stamtio Sotiropols, a professor of computational neurimizing University of Nottingham University StatementThe

Researchers trained a machine-learning model on more than 15,000 healthy volunteers without chronic disease to estimate “brain age” of each person so that their brain would determine how old or older they look older with its chronological ages. Then they used this tool to evaluate the age of MRI brain scans in two biobank groups. When viewing the second scans in each group, the average difference between chronological and measured age in the epidemic group was 5.5 months more than the control group.

Researchers also learned that this acceleration of brain growth was more identified in the elderly, male and disadvantaged socio -economic backgrounds such as low educational level, uncertain job, or housing and health disadvantages.

“This study reminds us that brain health is not only by illness, but also by our daily environment,” the top author of the study said, in -in in -in A statement Released by the University of Nottingham. “The epidemic causes stress on people who are already facing inconveniences especially in people’s lives.”

Although brain growth was universally seen among the residents through epidemics, only infected people showed measurable cognitive weaknesses, it was a sign of Covid that was enrolled in the past. The survey found that those who were in the two scans of the epidemic were reduced to emotional flexibility and processing speed test performance. On the contrary, those who have not infected do not show any significant cognitive changes, suggested that structural aging does not always translate to visible functional symptoms.

However, writers have acknowledged that there are some important limitations for this observational study, which can bias the outcome. This Include the interval of time between people’s scans differing the two groups, as well as the uk biobank lacking reproduction from the most marginalized sectors of the british population.

Researchers also highlighted the possibility of reversing, as only two time point brain scans were analyzed, which means that there may be neurological recovery among these people in later years. “We still do not know whether observed changes may be the opposite, but this is an encouraging idea,” said Aur.
