Loneliness Linked to Lower Initial Memory Scores in Older Adults But Not Accelerated Decline

A six-year longitudinal study of 10,217 older adults aged 65-94 from 12 European countries published in Aging & Mental Health found that lonely individuals scored lower on memory tests at the start but did not experience faster cognitive decline over time. Researchers from Universidad del Rosario analyzed SHARE data and found age was the strongest predictor of memory level and decline rate, with accelerated drop-offs after age 75 and more pronounced decline after 85. Depression and chronic diseases also reduced initial memory scores, while physical activity acted as a cognitive buffer.
