A global study published in Nature Human Behavior finds that regular use of digital technology, from smartphones to computers, is linked to a significantly lower risk of cognitive decline among older adults. For Thailand’s rapidly aging population, this research offers a hopeful view on how digital engagement can support brain health in later life.
The study analyzed 57 projects worldwide, involving more than 411,000 adults with an average age of 69. The key takeaway: middle-aged and older individuals who frequently use digital devices were about 58% less likely to experience cognitive impairment than peers who avoid technology. The researchers stressed there is no credible evidence of a widespread digital “brain drain” from ordinary use of devices.
This finding matters for Thailand, where demographic shifts are driving concern about dementia. The National Economic and Social Development Council projects that by 2030, more than a quarter of Thais will be elderly. Thai families often face emotional and economic strain as conditions like Alzheimer’s disease rise. The integration of digital technology into daily life, once seen as confusing by some elders, may actually offer cognitive and social benefits. Data from Thailand’s health authorities indicates growing interest among seniors in using mobile messaging apps, online exercise programs, and digital health resources.
The research team, led by clinical neuropsychologist Dr. Jared Benge from Dell Medical School at the University of Texas at Austin and Dr. Michael Scullin, a psychologist and neuroscientist at Baylor University, suggests that learning and adapting to technology itself can act as cognitive exercise. Regular device use presents new tasks, promotes adaptability, and strengthens memory and problem-solving pathways. Digital tools also facilitate social connection, enabling video calls with family members and quick access to health information.
“Our review found no evidence that ordinary digital technology use harms brain function. In fact, it often helps keep the mind engaged and connected,” said Dr. Scullin in a Baylor University press release. He added: “If a parent or grandparent is staying away from technology, consider encouraging small steps—photo sharing, messaging, or calendar apps on a smartphone or tablet.”
For Thai elders, these findings offer reassurance and practical guidance. Community health volunteers—central to Thailand’s public health system—often teach seniors to use LINE or join online exercise classes. In regions like Chiang Mai and Nakhon Ratchasima, programs such as “Senior Online Centers” help older adults explore tablets for games, news, or communicating with grandchildren.
While concerns about device addiction, isolation, and misinformation persist, the meta-analysis emphasizes responsible, moderate use as beneficial. Importantly, engaging with digital tools does not replace tradition. Many temples and senior centers now blend traditional practices with digital outreach, including livestreamed meditation and online cultural workshops, to broaden access to learning for all ages.
Thailand’s past saw cognitive decline viewed as an inevitable part of aging and little technology in daily life. Today, digital services touch banking, healthcare, and even monk-led dharma talks, reflecting evolving times and new opportunities for mental engagement. Nevertheless, a digital divide remains in rural areas, where access to devices and training is uneven. Policymakers can help by expanding internet access and supporting basic digital literacy for all ages.
Looking ahead, technology’s role in elder care is likely to grow. Telemedicine, online exercise classes, brain-training apps, and video calls are becoming increasingly integrated into daily life. With supportive public policy and family engagement, Thai elders could gain improved mental health and social inclusion while retaining traditional community values.
For individuals and families seeking practical steps, the message is clear: help a loved one take their first online steps. Teaching a grandparent or parent to use social messaging, word games, or easy cooking videos online is safe and may help protect cognitive health. As researchers note, exposure to digital technology can be an important factor in supporting healthy brain aging.
As ongoing research continues to clarify the link between technology use and cognitive health—particularly in an Asian context—Thai families, care providers, and policymakers are encouraged to view digital engagement as part of a holistic approach to lifelong mental well-being.
