Research has found that older adults who use digital devices regularly experience lower rates of cognitive decline compared to those who use them less frequently. A study analyzing over 400,000 adults from more than 57 published studies found no evidence to support the claim that screen time leads to “digital dementia.” Instead, the researchers suggest a two-way relationship where using technology can provide cognitive benefits and compensate for age-related brain decline.
The findings challenge the common perception that technology is detrimental to brain health. Scientists believe that digital tools can help engage in complex activities, boost social connections, and compensate for declining cognitive abilities. The study’s authors argue that the benefits of technology depend on how it is used, with passive use being less beneficial than more active engagement.
Experts welcome the study as a significant step towards understanding the relationship between technology and brain health. They emphasize that while the exact mechanism behind this association is still unclear, the results suggest a positive link between good cognitive health and digital technology usage. The researchers hope that future studies will help design interventions to support those at risk of cognitive decline.
