The interrelationship between social connectedness and social-engagement and its relation with cognition: a study using SHARE data

This study investigated how social connectedness (quality and structure of relationships) and social-engagement (involvement in activities) interact to influence cognitive function in adults aged 50+ across Europe and Israel. Using data from over 66,000 participants, the results showed that both factors independently boost cognition, and their combination provides the strongest cognitive benefits. When one factor is absent, the other compensates, emphasizing their complementary roles in maintaining cognitive health and resilience against decline.

Enhance cognitive health by actively building strong social ties (e.g., with family and friends) and participating in community activities like volunteering or clubs. Prioritize activities that foster both engagement and meaningful connections for maximum benefit. While the study shows strong associations, causality remains unproven, so integrate these habits with other health practices.
