NEW YORK — For years, digital devices have been blamed for harming attention spans and mental health — especially among teenagers. But new research suggests that for older adults, technology may actually help keep the mind sharp.
“Among the digital pioneer generation, use of everyday digital technology has been associated with reduced risk of cognitive impairment and dementia.” — Michael Scullin, Baylor University
A sweeping analysis published in Nature Human Behavior found that seniors who regularly used computers, smartphones, or the internet scored higher on cognitive tests and were less likely to be diagnosed with dementia than peers who avoided technology. The findings challenge years of concerns about so-called “digital dementia” and open new questions about how everyday tech use might protect aging brains.
The research, co-authored by Baylor University cognitive neuroscientist Michael Scullin and University of Texas at Austin neuropsychologist Jared Benge, reviewed 57 studies covering more than 411,000 adults aged 50 and older. “Among the digital pioneer generation, use of everyday digital technology has been associated with reduced risk of cognitive impairment and dementia,” Scullin told The New York Times. Remarkably, nearly 90% of the studies reviewed showed a protective cognitive effect.
Tech as a Mental Workout
While overuse of screens has been linked to attention and mental health problems in children, researchers say the dynamic is different for older adults. “It flips the script that technology is always bad,” said Dr. Murali Doraiswamy, director of the Neurocognitive Disorders Program at Duke University, in comments to the Times.
For seniors, navigating rapidly evolving devices — from troubleshooting software glitches to adapting to new operating systems — can be a form of mental exercise. “If you don’t give up on them, if you push through the frustration, you’re engaging in the same challenges that studies have shown to be cognitively beneficial,” Scullin explained.
In addition, technology can reinforce other brain-healthy habits by helping older adults maintain social connections, set reminders, and manage daily tasks like shopping or banking. A CNN health report noted that social engagement is one of the most consistently proven factors in reducing dementia risk.
Real-World Benefits and Limitations
The analysis focused on “technology use in the wild” — the kind of tech engagement that happens naturally over decades rather than in short-term lab settings. Walter Boot, a psychologist at Weill Cornell Medicine’s Center on Aging and Behavioral Research, told the Times that the study’s real-world scope makes its conclusions “plausible,” even if causality remains unclear.
Skeptics caution that tech use could simply be a marker for other factors, like higher education or income. Still, when researchers adjusted for demographics, health, and socioeconomic status, the association between tech use and better cognition persisted.
Balancing Benefits and Risks
Experts stress that not all tech use is positive. Online fraud disproportionately targets older Americans, with the Federal Trade Commission reporting that while seniors are less likely to report scams than younger people, their financial losses are typically far greater. Excessive screen time may also crowd out physical activity and in-person interaction.
“Technology cannot substitute for exercise, good nutrition, and real social contact,” Doraiswamy cautioned.
One Senior’s Story
For 67-year-old Wanda Woods of Denver, tech has been a lifelong companion — from magnetic-card word processors in the 1970s to AI chatbots today. Woods, now an instructor with AARP-supported Senior Planet, uses ChatGPT and Google’s Gemini to plan family vacations. “It keeps me in the know,” she said, adding that staying tech-savvy makes her feel both connected and mentally agile.
Her experience mirrors what researchers suggest: adapting to constant tech change may help older adults preserve — and even enhance — cognitive resilience in a digital age.
As Boot put it, “A new technology gets introduced, and there’s panic. Over time, we see it’s not so bad and may actually have benefits.”
