Digital dementia is deterioration of brain functioning caused by overuse of technological devices. As my readers know, my goal is to demystify aging and provide credible information based on facts and empirical research. There are two sides to the digital dementia conundrum.
There is evidence that “tech overload” or “outsourcing” of the brain by overuse of technology creates dementia-like symptoms across all age groups. Symptoms include delayed recall, reduced comprehension, and poor concentration. There is evidence that overuse of screen devices by children impedes brain development, setting the stage for learning detriments.
Sitting slumped over for hours on end may have deleterious impact on brain functioning, according to several chiropractic websites, although I found no scholarly documentation on the topic. It makes sense that maintaining good posture while using devices is healthier than sitting slumped over. Conversely, studies also suggest that use of smartphones and internet may improve cognitive functioning among older adults, as internet use may offset social isolation. The lesson learned from global centenarian studies is this: Everything in moderation. It applies to technology use, too.
