Loneliness has strong ties to long-term dementia risk in older adults, a 10-year study has found.
The researchers tracked development of dementia over a 10-year period, measures of cognition and brain volume and other dementia-related changes based on brain scans.
In addition, lonely participants younger than age 80 who did not have genetic risk for dementia had a three-fold greater risk of developing the condition than the not-lonely cohort.
