BIG NEWS IN WOMEN’S HEALTH 🧠✨
A major new study is adding to what we’re learning about hormone replacement therapy (HRT) and long-term brain health.
Researchers followed 183,450 postmenopausal women for approximately 13 years and found that HRT use was associated with:
🧠 10% lower risk of dementia overall
🧠 16% lower risk of Alzheimer’s disease
🧠 26% lower risk of dementia in women who had surgical menopause
That last number is especially interesting.
For years, conversations surrounding hormone therapy have focused heavily on potential risks. But newer research is helping us understand that the story is much more nuanced — and factors like when hormones are started, why they’re needed, the type of hormone used, and how it’s administered may matter enormously.
One important distinction: this was an observational study, so it does not prove that HRT prevents dementia, and HRT should not be prescribed solely for dementia prevention based on these findings.
But it is another important piece of a much larger conversation about estrogen and the brain.
Menopause isn’t simply about hot flashes.
Estrogen receptors exist throughout the body, including the brain, bones, cardiovascular system, skin, muscles, and genitourinary system. When estrogen levels change, the effects can extend far beyond your menstrual cycle.
Women deserve thoughtful, individualized conversations about menopause and hormone therapy based on current evidence, their symptoms, their medical history, and their personal risk factors — not fear or outdated blanket statements.
And the research keeps getting more interesting. 🧠💗
Hormone therapy is not appropriate for everyone. Treatment decisions should always be individualized with a qualified healthcare provider.
