Response: A rapid decline in estrogen with menopause may be associated with an increased risk of Alzheimer’s disease risk in women. This study was conducted in newly postmenopausal women who received 17β-Estradiol via a skin patch or conjugated equine estrogen orally or placebo.

Those who received 17β-Estradiol patch had reduced β-amyloid deposits, the plaques found in the brains of people with Alzheimer’s disease, three years after the end of the hormone therapies.

In the study, women with APOE e4 — one form of the most common gene associated with late-onset Alzheimer’s disease — who received the 17β-Estradiol patch had lower levels of β-amyloid deposits than those who received placebo. What should readers take away from your report?

Response: This study showed, for the first time, that the β-amyloid amyloid deposition ─ a hallmark of Alzheimer’s disease ─ is reduced in newly postmenopausal women who received 17β-Estradiol patch form of hormone therapy. Women with the APOE e4 allele, who have a greater genetic risk for Alzheimer’s disease, particularly benefited from this therapy. What recommendations do you have for future research as a result of this study?

Response: Our results need to be confirmed in the larger group of women. We are seeking funding to perform amyloid PET imaging at eight KEEPS study sites around the U.S. Is there anything else you would like to add?

Response: If confirmed in a larger group of KEEPS participants, this finding has the potential to change the concepts for preventive interventions that drive the Alzheimer’s disease field today, and may have a significant impact on women making the decision to use hormone therapy in the early postmenopausal years. Thank you for your contribution to the community.
