COVID Pandemic Accelerated Brain Aging, Study Finds
Scientists have found that the COVID-19 pandemic may have made people's brains age faster, even if they didn't get sick.
They looked at brain scans and saw that, on average, people's brains seemed older than they should have been.
This effect was more noticeable in men and people from less wealthy backgrounds.
It's like the stress and changes during the pandemic might have sped up brain aging a little bit.
The study used a large amount of health information from many people to find these things out.
Interestingly, even though brains looked older, it didn't always mean people had trouble thinking or remembering things.
Research suggests the COVID-19 pandemic accelerated brain aging, even in those uninfected.
Study found that men might be more affected by this accelerated brain aging.
The study used data from the UK Biobank, analyzing scans of over 15,000 individuals.
Mental agility declined only in participants who contracted COVID-19.
Researchers found a 5.5-month acceleration in aging linked to the pandemic.
