Whether or not you were infected by Covid-19, the pandemic experience made our brains age faster, according to a new study published in Nature Magazine. This is significant because it shows that it is the cumulative stress of lockdown rather than the virus alone, the sense of vulnerability, isolation and loss which have impacted brain health.
The scans showed that pandemic-era brains aged about 5.5 months faster compared to the brains of those studied before the pandemic. The impact seemed to be greater in men, the elderly and people with more compromised health, lower educational status and income. Researchers used serial neuro-imaging data from the UK Biobank (UKBB) study and brain scans from before the pandemic and after. “This study highlights the importance of monitoring brain health and promoting healthy lifestyle habits to support cognitive well-being in the long run,” says Dr MV Padma Srivastava, chairperson, neurology, Paras Health, Gurugram.
What does this study mean?
The study found that brain ageing sped up during the Covid-19 pandemic — even in people who were never infected. This means the changes weren’t just caused by the virus, but also by the stress, isolation and disruption to daily life that everyone experienced. It shows how strongly our mental and emotional environment can affect brain health. And how we should build resilience to deal with any crisis.
Does it also mean that crisis situations could lead to brain health issues in the future?
While the study observed signs of accelerated brain ageing during the pandemic, it does not confirm any long-term brain health issues. However, it highlights the importance of monitoring brain health and promoting healthy lifestyle habits to support cognitive well-being in the long run.
Can this ageing be reversed by reducing daily life stress, increased social interactions, increased activity and so on?
While the study did not directly test whether these changes can be reversed, existing research suggests that maintaining a healthy lifestyle — including managing stress, staying socially connected, engaging in regular physical activity and keeping the mind active — can be beneficial for overall brain health and may help support recovery over time.
How to look after one’s brain health?
Looking after brain health involves managing stress, staying physically active, getting enough sleep, maintaining social connections, eating a balanced diet, taking small breaks and keeping the mind engaged through learning and mental activities. Foods rich in Omega-3 fatty acids, antioxidants and vitamins can help improve brain health. Exercises boost cognitive function. Give your brain a workout by engaging it through puzzles, reading and learning new skills.
