What This Means
This research suggests that among older adults living independently in Spain, engaging more in leisure activities linked to cognitive reserve (the brain's ability to stay resilient as it ages) was associated with lower stress levels and, perhaps counterintuitively, greater feelings of loneliness in men. These associations were not found in women, though the researchers caution that the study was small and exploratory, so these gender-specific results need to be confirmed in larger studies. Higher engagement in leisure activities associated with cognitive reserve was also linked to better performance on certain attention tasks, but not to memory span performance.
The study used questionnaires measuring depression, anxiety, stress, life satisfaction, and loneliness alongside cognitive tests of memory and attention in 80 adults aged 65 to 101. The cognitive reserve scale used here specifically captured how much participants engaged in leisure activities thought to build cognitive reserve, rather than measuring cognitive reserve comprehensively. Because the study design was cross-sectional (a snapshot in time), it cannot determine whether leisure activities cause better cognitive outcomes or whether other factors are at play.
This research matters because it highlights the complex and sometimes unexpected relationships between how people spend their time, how they feel psychologically, and how well their brains function as they age. The finding that more leisure engagement was linked to higher loneliness in men, for example, suggests the relationship between an active lifestyle and emotional well-being in older adults is not straightforward. The authors call for larger, more targeted studies to better understand how lifestyle choices, emotional well-being, and brain health interact in older adults.
