Sense of Purpose Linked to Sharper Cognitive Function in Seniors
Translated & summarized from Maariv by baba
A new study from Israel suggests that a sense of purpose and contribution to others significantly protects cognitive function in older adults, particularly those with lower cognitive reserve. This feeling of being needed can compensate for earlier disadvantages and reduce depressive symptoms, leading to better brain health.

- Feeling needed compensates for lower education and social activity.
- Contribution to others reduces depressive symptoms.
- Meaningful roles are crucial for cognitive health in seniors.
- Intergenerational programs can foster a sense of value.
A surprising factor, a sense of benefit and contribution to others, may protect cognitive function in older adults, according to a joint study by Ben-Gurion University of the Negev and Safed Academic College. Researchers analyzed data from 476 Israeli adults aged 50 and above, who participated in the Survey of Health, Aging and Retirement in Europe (SHARE).
Participants were asked about their contributions to family, friends, and community, including providing time, money, or advice. Their cognitive performance was then assessed through tasks like immediate and delayed word recall and arithmetic problems. The analysis revealed a direct correlation between a sense of value and benefit and cognitive performance, explaining 34% of the variance in cognitive abilities.
This effect was particularly strong for individuals with lower "cognitive reserve," defined as those with less formal education and limited social activity. For this group, feeling needed by others can compensate for earlier life disadvantages. "Cognitive reserve is typically built throughout life through higher education, job complexity, and mental challenges, resources not equally accumulated by everyone," explained Professor Ella Cohn-Schwartz. "Our study shows that a sense of benefit and necessity to one's environment can be an accessible and significant compensatory mechanism."
Professors Cohn-Schwartz and Rabia Khlaileh emphasized that simply filling seniors' days with activities is insufficient. Instead, creating meaning through social and interpersonal roles where their voices are heard and skills are valued is crucial. The subjective experience and meaning individuals attribute to their contributions, not just the activity itself, are what protect the brain.
The study also found a link between a sense of benefit and fewer depressive symptoms, a known accelerator of cognitive decline. Individuals who felt more significant experienced less depression, partially explaining the connection to better cognition. Unlike education, which is difficult to change later in life, a sense of value and meaning is an achievable and inexpensive target for community intervention. The researchers advocate for policymakers and welfare organizations to invest in intergenerational programs, mentorship, and informal community leadership roles that allow older adults to share their life wisdom and feel valued.
