Key Takeaways

Researchers investigated if the association between loneliness and dementia risk in older adults could be mediated by sense of control. They also evaluated a second-order moderated mediational model by which working-memory capacity moderates the link between control beliefs and dementia risk among older adults. Participants were older community-dwelling adults (ages 60–93; N = 69). As per the findings, the association between loneliness and risk of dementia was significantly mediated by sense of control. Moreover, only in participants having poorer working-memory capacity, the indirect impact of loneliness on dementia risk via lowered sense of control was significant. These results were true when crucial covariates were controlled for. Experts concluded that control beliefs and working memory have a critical role in protecting against dementia risk.
