To reach the above conclusion, experts at the University of California, Davis (USA) tracked more than 13,000 people aged 45 and older for 15 years. Participants completed a questionnaire designed to assess their sense of purpose, goal setting, and goal achievement. The rating scale ranged from 1 to 6, with higher scores reflecting a stronger sense of purpose.
The final assessment showed that those living with greater purpose had a 28% reduced risk of cognitive decline, including mild cognitive impairment and dementia. This protective effect persisted even after accounting for factors such as educational attainment, symptoms of depression, and the APOE4 gene—a key genetic risk factor for dementia in older adults (Alzheimer's disease). Furthermore, those living with greater purpose also experienced a slower onset of cognitive decline.
According to expert Nicholas C. Howard, the lead author of the study, compared to using medication (which often comes with side effects and is expensive), living a purposeful life is a free, safe, and easy way to protect cognitive function. Older adults can build a purposeful life through relationships, setting goals, and participating in meaningful activities such as volunteering.
Scientists suggest that living with purpose is often linked to healthy habits – such as regular exercise, good sleep, social connection, and a nutritious diet. Living with purpose is also associated with reduced chronic stress and inflammation, and improved vascular function. These factors influence resilience to age-related changes.
