Regular and moderate internet use could reduce the risk of dementia in older adults, according to a study by NYU’s School of Global Public Health. The research, which tracked dementia-free adults aged 50-65 for up to 17 years, found that regular internet users had a 1.54% risk of developing dementia, compared to a 10.45% risk for non-users. However, using the internet for more than two hours per day could increase the risk of dementia.
