A recent study published in Alzheimer’s & Dementia has established a significant link between social engagement and a reduced risk of mild cognitive impairment (MCI) and dementia.
Dementia affects approximately 50 million people globally, leading to substantial economic and healthcare burdens. Research highlights social activity—including social support, marital status, participation in community events, and avoidance of loneliness—as a crucial factor in slowing cognitive decline. Engaging in social interactions appears to mitigate the risks associated with neurodegenerative conditions.
The study, involving 1,923 participants from the Rush Memory and Aging Project, with an average age of 80.4 years, followed individuals for 6.7 years. Results showed that 36% developed MCI, while 28% progressed to dementia. However, higher levels of social activity correlated with a 38% reduced dementia risk and a 21% reduction in MCI likelihood.
Notably, the most socially active individuals experienced a delay in dementia onset by approximately five years compared to those with lower social engagement. A similar five-year delay was observed in MCI development, emphasizing the protective role of social connections in cognitive health.
