How Does This Apply to Real Life?

The findings of this study are not surprising, considering the mounting evidence linking loneliness to poor health. Dementia is a spectrum, and the neuropathological changes in the brain start decades before symptoms appear. It’s essential to continue studying the link between loneliness and different cognitive outcomes or symptoms across this spectrum.

The study defines loneliness as a dissatisfaction with social relationships, which can impact cognitive function and daily life. The Centers for Disease Control and Prevention (CDC) notes that loneliness is often caused by a lack of meaningful or close relationships or a sense of belonging, which is a fundamental human need.

According to the National Institute on Aging, certain risk factors for loneliness include vision, hearing, and mobility problems; lack of transportation; living alone; death of a loved one or retirement; caring for a loved one who is unwell; and language barriers.

The Bottom Line

This meta-analysis found that loneliness is associated with a 31% increase in dementia. One of the best ways to prevent loneliness is to nurture strong, healthy relationships. If you feel you don’t have that in your life already, find ways to make connections. And if you know someone who appears to be lonely, reach out to them – you just might play a role in helping to keep their brain healthy and feel loved.
