In this powerful episode of Research Renaissance, host Deborah Westphal sits down with Dr. Rachel Buckley, Associate Professor of Neurology at Massachusetts General Hospital and Harvard Medical School. Together, they explore a growing body of research that challenges long-standing assumptions about sex differences in Alzheimer's disease.
Dr. Buckley shares her unexpected journey from skepticism to advocacy in studying how biological sex and hormonal changes—particularly around menopause—can influence Alzheimer's risk, pathology, and progression. From PET scans to postmortem tissue studies, she unpacks what we now know about tau pathology in women, the role of hormone therapy, and how reproductive history may shape brain health.
You’ll also hear about:
- Why women are disproportionately impacted by Alzheimer’s—and why it’s more than just longevity
- How timing of hormone therapy may impact tau buildup
- Surprising research around pregnancy, caregiving, and even the X chromosome
- Where the research gaps still exist—and how AI might help close them
- Why training the next generation of sex-based neuroscientists is essential
Whether you’re a caregiver, clinician, researcher, or simply curious about how brain health intersects with gender, this episode offers eye-opening insight and hope for the future.
