Loneliness Lowers Seniors' Memory Baseline, Not Decline Rate

A six-year study of 10,217 Europeans aged 65–94 found that loneliness is linked to lower immediate and delayed memory scores at baseline, but does not speed up the rate of memory decline. Age is the main driver of decline, with depression and chronic diseases also reducing initial memory; regular physical activity improves baseline memory, providing a cognitive buffer. The findings highlight loneliness as a factor affecting initial cognitive performance rather than accelerating aging, underscoring the importance of addressing loneliness in aging populations.
