Could hormone replacement therapy have implications for brain health as well as menopause symptoms? 🧠
New research involving more than 183,000 postmenopausal women found that HRT use was associated with a 10% lower risk of all-cause dementia and a 16% lower risk of Alzheimer’s disease.
The association was stronger in some groups, including women who had undergone surgical menopause, and researchers also found that the timing of HRT initiation appeared to matter.
But there’s an important distinction: association does not prove prevention.
This was an observational study, so it cannot establish that HRT itself caused the lower dementia risk. Researchers say more work—including research capable of establishing causality—is needed.
HRT decisions should therefore remain individualized and based on a discussion of your menopause symptoms, health history and potential benefits and risks.
