Pandemic Stress Linked to Accelerated Brain Aging

Multiple studies analyzing data from over 15,000 adults in the UK Biobank found that the COVID-19 pandemic accelerated brain aging by an average of 5.5 months, even among those who were never infected. The effects were most pronounced in men, older adults, and individuals from disadvantaged backgrounds. Researchers attribute the accelerated aging primarily to pandemic-related stressors such as social isolation, economic uncertainty, and disrupted routines, rather than to the virus itself. While cognitive decline was more noticeable among those who contracted COVID-19, the broader population experienced subtle but measurable changes in brain structure. The permanence of these changes remains uncertain, though some researchers suggest they may be at least partially reversible. The findings highlight the significant impact of societal stress on brain health and the importance of supporting cognitive well-being during future crises.
