Implication

Comparative analysis identifies education, social networks, and lifestyle impacts on cognitive reserve in older adults, suggesting modifiable pathways for improvement.

Key Points

Investigate factors influencing cognitive reserve using MRI markers in older adults, focusing on education and social networks.
Analyzed MRI data from 279 visits of 201 older adults.
Assessed cognitive reserve as residual global cognition based on brain measures and demographic factors.
Used multivariate models to estimate effect sizes and mediation analyses to evaluate the impact of factors.
Higher educational attainment significantly linked to greater cognitive reserve.
Only occupational complexity with people showed a minor effect, diminishing in adjusted models.
Cognitive-oriented activities and social network bridging capital independently related to cognitive reserve, with bridging capital mediating 11% of the education-cognitive reserve link.
