🧠 Your brain may have aged faster during the pandemic, even without COVID-19 infection.

A UK Biobank study shows pandemic-era stressors accelerated brain aging by ~5.5 months, especially in older men and those from deprived backgrounds.

👏 Thanks to @alirezamnk , @IPFdoc and @SNSotiropoulos for this essential work!

Covid-19 has made our brains age faster, says a new study led by experts @MedicineUoN @UoNFacultyMHS and published @Nature even if you were never ill with the virus

برپایه پژوهشی به سرپرستی @alirezamnk در دانشگاه ناتینگهام، همه‌گیری کرونا یک تاثیر دیگر هم بر روی مغز بشر داشته: پیری زودرس! بر این اساس، فارغ از اینکه به کووید۱۹ مبتلا شده باشید یا نه، در دوران همه‌گیری مغزتان حدود شش ماه از حد معمول پیرتر شده است!

Rates of brain ageing accelerated during the COVID-19 pandemic, even among those who did not get infected with SARS-CoV-2, suggests a study of nearly 1,000 UK adults published in @NatureComms. https://t.co/qSF5z26pvm

The 2nd highlighted sentence in the conclusion makes the key point that Covid affected cognitive decline, especially in older people. Nature coverage here https://t.co/MEK3ByyNIv

New study alert:
Our latest research shows that living through the COVID-19 pandemic—even without infection—was linked to signs of accelerated brain ageing.
Published today in Nature Communications.

Why it matters:
This study adds to our understanding of how large-scale disruptions affect brain health, even in people without illness.
It underscores the need for mental and cognitive health support in future public health crises.

[Ali-Reza Mohammadi-Nejad @alirezamnk]

Does the pandemic impact brain health even without direct infection?
Yes, the pandemic alone induced accelerated brain ageing. Older individuals and those from deprived backgrounds were especially affected. This highlights the need to address broader social & health inequalities.

[Ali-Reza Mohammadi-Nejad @alirezamnk]

How did the #Covid_19 pandemic affect #BrainHealth?
Our new preprint shows a significant acceleration in brain ageing. Using longitudinal scans of 1300+ healthy #uk_biobank participants, we found an 11-month higher brain age gap post-pandemic.

What is the relationship between #Covid_19 and cognitive performance?
Accelerated brain ageing correlated with reduced cognitive performance in infected participants. Those who experienced the pandemic without infection had similar age-related cognitive declines as controls.
