ABOUT THIS EPISODE
Three new papers landed this week touching hormone therapy, brain aging, and lifestyle habits in perimenopause. Nykki breaks down what the Alzheimer's-HRT connection actually looks like in the current evidence, what "epigenetic age" means for real women, and why most perimenopausal women's health behaviors fall into one of three distinct clusters — and why that matters for how we talk about lifestyle advice.
Key Takeaways:
• The link between HRT and lower Alzheimer's risk is real in some studies, but timing is everything — starting hormone therapy early in perimenopause appears more protective than starting years after menopause.
• "Epigenetic age" is a way of measuring how old your cells act, not just how old you are. Early research suggests estrogen therapy may slow that biological clock, especially in women with stable blood sugar.
• A 2026 study using the COM-B behavioral model found perimenopausal women cluster into three distinct health-behavior profiles — and the majority fall into groups with significant gaps in either physical activity or stress management, not both.
• Narrative reviews summarize existing research rather than generating new data — they're useful for seeing the landscape, but they don't settle questions the way a large clinical trial does.
• The Alzheimer's-HRT research is promising enough to ask your doctor about, but not definitive enough to treat as a proven benefit yet.

Three new studies look at what women are actually eating — and what it's doing to their bones, their vaginal microbiome, and their bladder. Nykki breaks down what the research says and what, if anything, is worth changing this weekend.
Key Takeaways:

This episode covers a USA Today investigation into FDA warnings about UTIs turning fatal in menopausal women, a major global study finding women report more pain than men with the sharpest rise happening before age 55, and a controversy in Spain over an official menopause guide built almost entirel…
A new pilot study finds a possible link between a bone protein called osteocalcin and reduced brain connectivity in women with postmenopausal osteoporosis — raising questions about whether bone loss and brain fog share more biology than we thought. Then: a new study shows the ovaries don't just shu…
This episode covers three new studies from October 2026: a year-long look at topical finasteride for postmenopausal hair loss, early-stage animal research on a cherry compound and bone density, and a large blood-donor dataset showing how iron and hemoglobin levels shift by age and season — with rea…
A large new study reveals that hormonal change during menopause isn't gradual — it drops sharply right at the final period, which may reshape how we think about timing treatment. This episode also covers a lifespan look at metabolic health and menopause, and a rare but important case report about w…
