HRT linked to lower dementia risk, but timing and menopause type matter

In a UK Biobank study of 183,450 postmenopausal women followed for an average of 13.3 years, hormone replacement therapy use was associated with a modestly lower risk of dementia, with stronger associations in women who had surgical menopause or shorter natural estrogen exposure. The relationship also varied by age at HRT initiation, while the observational design means the findings cannot establish that HRT prevents dementia.
