Summary
This long-term study followed over 1,100 adults around age 80 for an average of 5 years to understand the relationship between social activity and cognitive decline. Researchers found that older adults who were more socially active experienced significantly slower declines in memory and other thinking skills, even after accounting for other factors like physical and mental activity, personality, and health. The most socially active participants had up to 70% slower cognitive decline compared to the least active.
