MedPage Today (2/9, George) reports, “Dementia incidence tripled in lonely older adults who otherwise would be expected to have relatively low risk based on age and genes,” investigators concluded in a study that “assessed 2,308 participants who were dementia-free at baseline with an average age of 73.” The study revealed that “lonely older people under age 80 without an APOE4 allele had a threefold greater risk of dementia…over 10 years than similar people who weren’t lonely.” What’s more, “regardless of age or APOE4 status, lonely older adults had a higher 10-year dementia risk compared with those who weren’t lonely.” The findings were published online in the journal Neurology.
