Israeli study points to purpose as path to healthier aging

An Israeli study by researchers from Ben-Gurion University of the Negev and Safed Academic College suggests that a sense of usefulness to others may protect the aging brain. The study surveyed 476 Israeli adults aged 50 and older, analyzing their self-reported contributions to family, friends, and community against their performance on cognitive tasks. The findings indicated a strong link between feeling needed and cognitive performance, accounting for approximately one-third of the variation in test results. This effect was particularly pronounced among individuals with lower cognitive reserve, such as those with less formal education. Prof. Ella Kuhn-Schwartz stated, "Our research shows that a sense of usefulness and necessity to the environment can constitute an accessible and significant compensatory mechanism." Researchers propose that integrating older adults into meaningful social roles, such as mentors or community leaders, could be a low-cost strategy for supporting cognitive health.
