A study of nearly 58,000 individuals across 24 countries suggests that intellectually demanding social activities may support long-term cognitive health. Researchers found these benefits were most apparent in participants with higher education levels and those residing in rural areas.
Why it matters
Engaging in mentally stimulating activities may help build or strengthen brain cell connections. This preventative approach is critical as dementia cases continue to rise globally, affecting millions.
The study tracked 57,793 individuals aged 57 to 73 over an average of six years. Currently, approximately 7 million people in the US and 1 million in the UK live with dementia, with the latter figure projected to reach 1.4 million by 2040.
The players
Shandong University
This Chinese public research university conducted the multi-country study on cognitive performance and social engagement.
The details
Researchers observed that activities like sports club membership and childcare correlated with higher scores on memory, planning, and multitasking tests. Conversely, participation in religious or political groups showed no consistent impact on cognitive performance.
Timeline
The findings were published in the Journal of Epidemiology & Community Health in 2026.
The total number of people living with dementia in the UK is forecasted to reach 1.4 million by 2040.
The Big Picture
This study builds upon the preventative framework established by the 2024 Lancet report on preventable dementia cases. It expands the scientific understanding of lifestyle factors by distinguishing between activities that provide cognitive stimulation and those that do not.
Older adults may consider prioritizing mentally stimulating social roles like childcare or sports training to potentially support cognitive longevity. Individuals with mild cognitive impairment should be aware that one third of those affected are expected to develop dementia within five years.
The takeaway
The study underscores the use it or lose it hypothesis, suggesting that cognitive engagement is a key factor in healthy aging. Consistent participation in complex social roles may offer a practical, low-cost strategy for maintaining brain function in later years.
