Lonely people have worse memory but don’t decline faster, study finds

Feeling lonely may be linked to worse memory in older adults, but it does not appear to make memory decline faster, according to a new study published April 14 in Aging & Mental Health.

The research analyzed 10,217 adults ages 65 to 94 from 12 European countries in the SHARE cohort. Participants who reported higher loneliness scored worse on both immediate and delayed recall at the start of the study.

But the seven-year follow-up found no evidence that lonely participants' memory declined faster than that of less-lonely peers. In other words, loneliness was associated with lower memory performance, but not a steeper downward trend over time.

The findings are being presented as an important distinction for aging research. They suggest that loneliness may affect how well older adults perform on memory tests without necessarily accelerating the rate of decline.

The study was first reported in an official Taylor & Francis release and then echoed in secondary coverage, including MedicalXpress. The research does not answer whether loneliness changes dementia risk directly, and the full implications will depend on how the findings are interpreted alongside other studies.

For now, the takeaway is straightforward: loneliness seems tied to worse memory in older adults, but not to faster memory loss.
