Digital Device Usage Linked to Lower Dementia Risk in Seniors
Embracing modern technology, such as smartphones and computers, may offer a surprising benefit for older adults. New research indicates that utilizing digital devices in later life could significantly reduce the risk of developing dementia and cognitive decline. Countering concerns about excessive screen time, the study suggests that engaging with technology is linked to improved brain health in seniors.
Study Highlights Cognitive Benefits of Technology for Older Adults
Despite rising apprehension regarding the pervasive nature of digital technology β exemplified by “brain rot” being recognized as a phrase of the year β a recent study reveals a contrasting perspective. Researchers discovered a compelling association between digital technology use and a noteworthy 58 percent decrease in the risk of cognitive impairment. Cognitive impairment encompasses a range of difficulties related to problem-solving, memory, language skills, and attention span.
The research team analyzed data collected from a substantial cohort of 400,000 individuals, with an average age of 68. Their findings suggest that for older adults who were introduced to computers, smartphones, and the internet later in life, the process of learning and using these technologies presents a valuable cognitive challenge.
Expert Insights on Brain Stimulation through Technology
Professor Michael Scullin of Baylor University in Texas, a leading researcher in the study, commented on the initial difficulties older adults often face when adopting new technologies. He noted, “One of the first reactions from older adults is often frustration with computers, expressing that they are difficult to learn.”


Professor Scullin clarifies that this initial struggle is “actually indicative of the cognitive exertion involved, which may be advantageous for brain function, even if it feels challenging initially.β He elaborated that technology necessitates continuous adaptation to evolving software and systems. “Engaging in this adaptation over years, despite potential frustration, could signify beneficial brain exercise.”

Social Connection and Cognitive Protection
Furthermore, Professor Scullin emphasized the role of video calls, emails, and messaging applications in sustaining social connections. He stated that maintaining robust social networks is another factor that can offer protection against cognitive decline.
Encouraging Technology Adoption in Later Life
Concluding on an encouraging note, Professor Scullin asserted that it is never too late to introduce technology to older relatives and friends. He advised, “Begin with simplicity and exercise considerable patience as they learn.”
