Dementia Research

UNSW Sydney researchers report in The Journals of Gerontology that older adults classified as socially frail had a roughly 47% higher risk of developing dementia over 12 years compared with non‑frail peers. The study followed 851 dementia‑free adults aged 70+ in Sydney’s suburbs, using biennial neuropsychological testing and adjusting for physical and psychological frailty and health history; low family/financial satisfaction, infrequent contact, and limited social activity were the strongest contributors.
