WHAT TO KNOW

• A recent study by researchers at UC Davis Health following 13,000 adults for up to 15 years found those who have a higher sense of purpose in life were 28% less likely to develop cognitive impairment, including mild cognitive impairment and dementia, than people who reported the lowest levels of purpose. The study found the protective effect linked to a higher sense of purpose was consistent across racial and ethnic groups, and remained statistically significant even after accounting for education, depression, and the APOE4 gene, a known risk factor for Alzheimer's disease. All study participants were aged 45 and older and had no cognitive issues at the start of the study period.

WHY IT MATTERS

• The findings suggest having a sense of purpose is a free, safe, and accessible way to help the brain stay resilient as it ages, even among people with known risk factors. The present study also adds to the body of research in recent years suggesting a sense of purpose is a crucial part of a healthy life. Research shows having a sense of purpose can help people live longer, reduce the risk of heart disease and stroke, and improve one’s quality of life, among other benefits.

CONNECT THE DOTS

• Previous research has shown that purpose comes from a wide range of activities and life behaviors, including maintaining good relationships, working or volunteering, engaging in spiritual practices or religious faith, pursuing personal goals like hobbies or milestones, and helping others. The authors of the present study say it’s never too early or too late to cultivate a sense of purpose by considering your life and what gives it meaning.
