Researchers identify social factor that may increase memory loss in older adults

Remaining socially active later in life has long been celebrated not only for fostering a sense of belonging in our golden years but also for its physical and mental benefits.

Now researchers have discovered one more reason to stay socially engaged in your later years, finding that loneliness can increase the risk of developing age-related memory loss.

After examining four combinations of social isolation and loneliness and their effect on memory in middle-aged and older adults over a six-year period, researchers from the University of Waterloo found that those who were socially isolated and lonely had the greatest decline in memory.

“As we expected, people who were both socially isolated and lonely had the greatest decline in memory, which intensified over the six years,” said Ji Won Kang, lead author of the paper and a PhD candidate in the School of Public Health Sciences at Waterloo.

“But we were surprised to find that loneliness alone had the second-greatest impact on memory, even though so many studies report on the dangers of social isolation without considering loneliness.”

Individuals who aren’t lonely but are socially isolated may still boost their mental capacity through solo activities such as reading, playing games, and engaging in hobbies that enhance memory and stimulate the brain, even without participating in social interactions.

Kang believes the findings highlight the importance of implementing community programs, particularly for older adults who face both social isolation and loneliness, as they are at the greatest risk of memory impairment.

“Older adults in the lonely category often have lower incomes than the other groups and may have structural barriers and health conditions preventing them from connecting to their communities,” she said.

“A solution could be to implement transportation or home-visit programs — something to address the societal issues that lead to them being more isolated.”

There are many ways to stay socially active in later life to help keep your memory sharp.

One great option is to join a club or group that aligns with your interests. Whether it’s a book club, gardening group, dance class, or a community service organisation, these settings offer a chance to connect with others who share your passions. Volunteering is another excellent way to engage with your community while making new friends.

Attending community events is also a fun way to socialise and meet people. Additionally, enrolling in a class or course on a topic you enjoy can introduce you to others who have similar interests.
