Technology's positive impact on cognitive function among the elderly

Technology's positive impact on cognitive function among the elderly

In a significant finding, a new analysis published in Nature Human Behavior reveals that technology use among older adults is associated with lower rates of cognitive impairment and slower cognitive decline, potentially reducing the risk of dementia [1][2].

The research, which focused on "technology use in the wild" over several decades, examined 57 studies involving over 411,000 seniors. Almost 90% of the studies found that technology had a protective cognitive effect [1].

Computerized cognitive training (CCT) programs delivered via mobile or digital platforms have been shown to improve cognitive function in older adults with mild cognitive impairment (MCI) and dementia. These programs can enhance global cognition and domain-specific skills such as memory, often outperforming traditional paper-based methods because they adapt difficulty levels to individual needs and are more accessible without trained experts [3].

Beyond cognitive training, emerging technologies like virtual reality, assistive robots, and AI-driven tools support mental health by providing personalized interventions, emotional support, and real-time monitoring, which may benefit older adults' cognitive and behavioral health and potentially delay progression of impairment [4].

However, technology readiness varies among older adults, influenced by factors such as age and gender. Some groups may experience more "technology trepidation" and need additional support to fully benefit from these digital health and cognitive interventions [5].

Wanda Woods, a new instructor with Senior Planet in Denver, is one such individual who has embraced technology in her personal and professional life. Despite growing up in an analog world, Wanda started a computer training business in 2012 and has helped numerous older people learn and stay abreast of technology [6].

Researchers like Michael Scullin, a cognitive neuroscientist at Baylor University, and Jared Benge, a neuropsychologist at the University of Texas at Austin, have found that seniors who use technology have better cognitive test scores and lower rates of cognitive impairment or dementia diagnoses compared to those who avoid technology or use it less frequently [1][7].

However, it's important to note that constant updates, troubleshooting, and learning new operating systems may also be cognitively beneficial [8]. On the other hand, online fraud and scams target older adults, with the Federal Trade Commission reporting that they lose much higher amounts compared to younger people [9].

Psychologist Walter Boot, from the Center on Aging and Behavioral Research at Weill Cornell Medicine, expressed skepticism about the long-term benefits of online brain-training experiments but found the study's conclusions plausible [2]. Neurologist Doraiswamy suggests that engaging with technology may have been part of the pattern contributing to the declining dementia rates, along with factors like reduced smoking, higher education levels, and better blood pressure treatments [10].

In summary, technology use appears to positively impact cognitive health in older adults by reducing decline risk, improving cognitive functioning in those already impaired, and enabling tailored behavioral interventions. Attention to technology readiness and accessibility is key for maximizing benefits [1][3][4][5].
