Loneliness linked to memory impairment in older adults

A six-year longitudinal study involving over 10,000 adults aged 65-94 reveals a significant link between loneliness and memory impairment in older individuals. The research, published in Aging & Mental Health, indicates that higher levels of loneliness correlate with lower scores on immediate and delayed recall tests. While loneliness appears to affect the initial state of memory, it does not accelerate the rate of cognitive decline over time. The study also highlights the positive impact of physical activity on baseline memory scores, suggesting it acts as a cognitive buffer against age-related changes.
