Digital Engagement Could Protect Older Thais from Dementia, New Study Finds
A major international study suggests that regular use of digital technology may guard against cognitive decline in older adults. In Thailand, where aging populations pose rising public health questions, the findings offer practical insights for families, caregivers, and policymakers. The research, published in Nature Human Behavior, indicates that smartphones, computers, and messaging apps could help maintain brain health as people grow older.
The analysis pooled data from more than 411,000 adults across 136 high-quality studies worldwide. Researchers tested two opposing ideas: that lifelong digital exposure leads to “digital dementia,” and that digital engagement builds a cognitive reserve that strengthens thinking and memory in later life. The data favor the latter, showing a 58% lower risk of cognitive impairment among those who used digital technology, after accounting for age, education, income, baseline cognition, and health factors.
