Volunteering late in life is associated with better cognitive function in older adults\u2014specifically, better executive function and episodic memory, according to a new study.<\/p>\n

“We hope these new data encourage individuals of all ages and backgrounds to engage in local volunteering\u2014not only to benefit their communities, but potentially their own cognitive and brain health,” says Donna McCullough, chief mission and field operations officer for the Alzheimer’s Association.<\/p>\n

Volunteer activities<\/a>\u2014such as supporting educational, religious, health-related, or other charitable organizations\u2014allow older adults to be more physically active, increase social interaction, and provide cognitive stimulation that may protect the brain.<\/p>\n

However, there has been a lack of information on the relationship between volunteering and cognitive function, especially in large, diverse populations.<\/p>\n

For the study, the researchers examined volunteering habits among an ethnic and racially diverse population of 2,476 older adults. The participants are in the Kaiser Healthy Aging and Diverse Life Experiences Study (KHANDLE) and the Study of Healthy Aging in African Americans (STAR).<\/p>\n

The study group had an average age of 74 and included 48% Black, 20% white, 17% Asian, and 14% Latino participants. A total of 1,167 (43%) of the participants reported volunteering in the past year.<\/p>\n

The researchers found that volunteering was associated with better baseline scores on tests of executive function and verbal episodic memory<\/a>. This was true even after adjusting for age, sex, education, income, practice effects, and interview mode (phone versus in-person).<\/p>\n

Those who volunteered several times per week had the highest levels of executive function.<\/p>\n

“Volunteering may be important for better cognition in late life and could serve as a simple intervention in all older adults to protect against risk for Alzheimer’s disease and associated dementias,” says Yi Lor, an epidemiology doctoral student at the University of California, Davis. “Our next steps are to examine whether volunteering is protective against cognitive impairment, and how physical and mental health may impact this relationship.”<\/p>\n

Volunteering was also associated with a trend toward less cognitive decline<\/a> over the follow-up time of 1.2 years, but this association did not reach statistical significance.<\/p>\n

“You’re not in control of your family history or age\u2014you can’t turn back the clock. But you are in control of how you spend your day and life,” says Rachel Whitmer, the study’s principal investigator. “Volunteering is about keeping your brain active. It’s also about socializing, which keeps you engaged and happy, and potentially lowers stress.”<\/p>\n

The researchers presented their findings at the Alzheimer’s Association International Conference 2023 in Amsterdam.<\/p>\n
