A new study analyzing over 10,000 adults aged 65 to 94 in 12 European countries reveals that higher levels of loneliness correlate with poorer memory test scores at the outset. However, over a seven-year period, the rate of memory decline was similar across participants, regardless of their reported loneliness.
Researchers suggest this indicates loneliness may affect the initial state of memory more than its progressive decline. While loneliness is often considered a risk factor for cognitive decline, these findings add nuance to the debate, indicating it may not directly speed up the progression of memory loss.
The study, which used data from the Survey of Health, Ageing and Retirement in Europe (SHARE), found that participants reporting higher loneliness also tended to have other health conditions like depression, high blood pressure, and diabetes, suggesting loneliness might be part of a cluster of health risks.
Experts emphasize that these findings do not suggest loneliness is harmless, as the damage may occur earlier in life before detection in older age. Maintaining social and mental engagement through activities like book clubs or meeting friends is crucial for overall brain health in seniors.
