A new study suggests that engaging in social activities can significantly reduce the risk of developing dementia. Researchers found that older adults who participated in more social activities had a 38% lower risk of dementia and a 21% lower risk of other mild cognitive impairments compared to those with fewer social interactions.
Humans are social creatures. Many of us enjoy spending time with friends and family doing social activities, like going out to dinner, attending sporting events, and participating in book clubs. According to the, being social offers a myriad of health benefits, including emotional regulation, reduced stress and anxiety, better sleep, and a reduced risk of heart disease and stroke.
“This study is a follow-up on previous papers from our group showing that social activity is related to less cognitive decline in older adults,” said Bryan James, PhD, associate professor of internal medicine at Rush, The study surveyed 1,923 older adults without dementia, with an average age of 80, who are part of the Rush Memory and Aging Project. During the survey period, 545 participants developed dementia, while 695 developed other mild cognitive impairments. Researchers used a questionnaire to measure the participant's social activity. Questions included how often in the last few years they had participated in certain social activities, such as playing Bingo, going on overnight trips, visiting friends and family, going to sporting events, and going to restaurants. At the start of the study, none of the participants showed signs of cognitive decline; however, after five years, the results showed that the participants with more social interactions had reduced rates of dementia. With this information, the study suggests that an increase in social activities could lower the risk of dementia by 38 percent and could lower the risk of other mild cognitive impairments by about 21 percent compared to those who partake in fewer social activities. A five-year delay in dementia development could reduce the financial cost of dementia care by 40 percent per person who may develop it and add three years to their lifespan. According to the researchers, social activities can help “strengthen neural circuits in the brain,” giving them a boost against the pathology buildup that occurs as we age. Social gatherings can stimulate the same parts of the brain associated with memory and thinking. “Social activity challenges older adults to participate in complex interpersonal exchanges, which could promote or maintain efficient neural networks in a case of ‘use it or lose it,’” James said in a press release. The study authors say that more research is needed to determine how well social activities can help with cognitive decline, but until then, there’s no time like the present to gather with your loved ones and play a game or two of Bingo.
