Large-scale observational study links HRT use to reduced dementia risk in postmenopausal women

A study of over 180,000 postmenopausal women in the UK indicates a 10% lower incidence of dementia and a 16% lower incidence of Alzheimer's among HRT users. While the findings suggest a potential protective effect, the observational nature of the research leaves causality unconfirmed and does not account for potential confounding variables like socioeconomic status or baseline health.
