If you have older family members looking to brush up on their social media skills, this could be more than a nice gesture. A new study published in the Journal of the American Geriatrics Society suggests that regular internet use in older adults may have unexpected benefits for brain health, potentially lowering their risk of developing dementia.
The Link Between Internet Use and Dementia Prevention
The study tracked 18,154 adults aged 50 to 65 over about eight years, none of whom had dementia at the start. Researchers found that those who used the internet regularly were roughly half as likely to develop dementia compared to those who didn’t use it.
How Internet Use May Help the Brain
Researchers proposed that online engagement might build what’s called “cognitive reserve,” a factor thought to help the brain age more healthily. Dr. Virginia W. Chang from New York University’s School of Global Public Health noted that this mental engagement may compensate for some of the natural effects of aging on the brain.
Time Online Matters, But Moderation is Key
Interestingly, people who spent up to two hours online daily showed the lowest risk of dementia. Those who spent six to eight hours online had a slightly higher risk, though this finding was not statistically significant, and researchers emphasized the need for more investigation.
Exploring the Benefits of Intellectual Stimulation
While the study didn’t track specific online activities, previous research shows that mentally stimulating activities may help prevent cognitive decline. For example, studies have linked jobs requiring mental stimulation with lower dementia risk, hinting that engaging in online learning or information-seeking could be similarly beneficial.
Alzheimer’s Disease and Lifestyle Factors
As the number of dementia cases continues to rise, experts are investigating factors beyond medication to help delay or prevent dementia. Dr. Claire Sexton from the Alzheimer’s Association highlighted the importance of identifying lifestyle changes, though she cautioned that this study alone doesn’t establish cause and effect.
Lifestyle Interventions for Cognitive Health
Although internet use isn’t on the CDC’s official list of dementia-preventing activities, other lifestyle choices can make a difference. Keeping physically active, sleeping well, managing blood pressure, and staying socially connected are known to support cognitive health.
The Role of Social Media in Reducing Isolation
Internet access can also help older adults stay connected to family, friends, and community through social media, which may protect against loneliness—a factor that has been linked to a higher risk of dementia in several studies.
Looking Forward to More Research
While the study adds to our understanding, experts like Dr. Sexton urge for more comprehensive research to explore the direct impact of internet use on dementia risk. With continued research, doctors may one day recommend digital engagement alongside other lifestyle changes to help keep dementia at bay.
