Description
Quinn Lin, Mahsa Dadar, Michael Oliver, and Cassandra Morrison asked whether loneliness speeds memory and thinking decline in older adults, and whether the effect differs by race, in a 2025 study. About a quarter of older adults feel socially cut off, and that feeling has been tied to faster decline. How the link varies across groups was less clear.
The team followed over 3,000 adults in a long-running database, with more than 20,000 check-ins across ten years. People were split by race and by high or low loneliness scores. Lonely White adults declined faster than both lonely and non-lonely Black adults in every test area. Within each race, lonely adults also declined faster than their non-lonely peers. The authors call the loneliness link robust, with the steepest slide among White adults.
