In today’s world, the constant hum of smartphones and tablets has become an inescapable part of our daily lives, often leading to concerns about their potential negative impacts, particularly as we navigate the complexities of aging.
It’s a common assumption that these ubiquitous digital devices might contribute to a decline in our mental acuity over time. However, a closer look reveals a surprising twist: Could these technologies, so often viewed with suspicion, hold the potential to safeguard our cognitive abilities as we age?
Recent research is turning the tide on the fears that smartphones, tablets, and other digital devices could contribute to dementia in later life.
Instead, studies reveal a fascinating twist: older individuals who regularly engage with technology may experience lower cognitive decline rates than their less tech-savvy peers.
This revelation comes from an extensive analysis of published studies encompassing over 400,000 older adults. The findings suggest that those over 50 who routinely use digital devices are better off cognitively than those who don’t.
While it’s unclear if technology is actively staving off mental decline or if people with sharper cognitive skills are more inclined to use digital tools, the implications are significant.
Dr Jared Benge, a clinical neuropsychologist at UT Health Austin’s Comprehensive Memory Center, offered a refreshing perspective.
‘For the first generation that was exposed to digital tools, their use is associated with better cognitive functioning,’ he explained.
The study, which was published in Nature Human Behaviour, analysed 57 studies examining the use of digital technology by 411,430 adults worldwide, with an average age of 69.
The conclusion? There’s no evidence to support the ‘digital dementia’ hypothesis, which posits that lifelong use of digital technology leads to mental decline.
On the contrary, using computers, smartphones, and the internet is linked with a lower risk of cognitive impairment.
But why might this be the case? The researchers propose a two-way relationship. Not only are individuals with better cognitive abilities more likely to embrace technology, but cognitive benefits can also be gained from using it.
‘We think the three Cs might be important: complexity, connection and compensatory behaviours,’ Benge said.
Digital tools can provide complex activities, enhance social connections, and compensate for cognitive decline, allowing people to function more effectively in their daily lives.
For instance, using GPS (Global Positioning System) for navigation or setting reminders for appointments and medications can help offset memory challenges. These compensatory uses of technology can be a boon for maintaining independence and cognitive health.
The way we use our devices also matters. Passive, sedentary screen time, akin to watching television, is unlikely to yield cognitive benefits.
However, mentally stimulating activities, social interactions, and compensatory uses of technology are considered beneficial for cognitive aging.
Experts in the field, like Professors Peter Etchells and Sam Gilbert, acknowledged the importance of the study in challenging the alarmist views of ‘digital dementia.’
Etchells, the director of the Centre for Research on Science and Society at Bath Spa University, said: ‘This is a really nice study that shows the research area is starting to mature. It’s starting to move beyond the blind acceptance that screen time is something useful to talk about. It’s starting to pose what the next questions should be.’
Gilbert, a cognitive neuroscience professor at University College London, stated that the research demonstrated ‘a clear connection’ between using digital technology and maintaining cognitive function in later life.
‘The explanation for this link is still not fully clear: we cannot be sure whether technology usage itself preserves cognitive ability, whether preserved cognitive ability leads to more frequent use of technology, or most likely some combination of the two. Nevertheless, this work challenges alarmist ideas about so-called “digital dementia” and instead suggests that using digital technology can be good for brain health.’
Dr Vincent O’Sullivan, an economist from the University of Limerick in Ireland, also approved the study.
‘The common perception, at least among media commentators, is that technology is making us stupid or forgetful. These researchers, through meticulous analysis of a vast academic literature, show that there is a positive association between good cognitive health and digital technology usage,’ he explained.
‘Once we understand the mechanism, we can hopefully design interventions for those at risk of cognitive decline.’
