Social participation and risk of developing dementia

This systematic review discusses the role of social participation in reducing the risk of developing dementia. It consolidates evidence from observational studies, indicating that engaging in social activities can lower dementia risk by 30–50%. Social participation likely supports cognitive health through mechanisms such as reducing stress, improving brain maintenance, and building cognitive reserve. Although some associations may not be causal, the findings highlight the importance of social interaction for brain health and the potential for targeted public health interventions.

Increase your social participation by joining community groups, engaging in hobbies with others, or volunteering. These activities may help reduce dementia risk by promoting mental stimulation and social connection. While observational research supports this advice, further studies are needed to establish causation. Pair this with other healthy lifestyle practices for optimal results.
