New research published in the Journal of the American Geriatrics Society found a link between regular use of the internet and a lower risk of dementia.

For the study, investigators followed 18,154 dementia-free adults aged 50 to 64.9 years for a median of 7.9 years and a maximum of 17.1 years. During follow-up, 4.68% of participants were diagnosed with dementia.

Regular internet usage was associated with approximately half the risk of dementia compared with non-regular usage. This link was found regardless of , race-ethnicity, sex, and generation.

"Online engagement may help to develop and maintain , which can in turn compensate for aging and reduce the risk of dementia," said corresponding author Virginia W. Chang, MD, Ph.D., of New York University.
