Associations between social health factors, cognitive activity and neurostructural markers for brain health – A systematic literature review and meta-analysis

This systematic review and meta-analysis examined the link between social and cognitive activities and brain structure across the lifespan. The study analyzed 43 studies, finding that engaging in social and cognitive activities was modestly associated with brain health markers like larger hippocampal volumes and better white matter integrity. However, the findings were inconsistent due to methodological differences. These results suggest that maintaining an active social and cognitive life may support brain health and slow cognitive aging.

Incorporate social and cognitive activities into daily life, such as joining clubs, maintaining a social network, or engaging in puzzles and learning new skills. While the research indicates modest benefits, its variability suggests combining these activities with other proven health practices for cognitive resilience.
