As a menopause coach and advocate for women’s health, I always emphasise the importance of informed decision-making when it comes to Hormone Replacement Therapy (HRT).
A recent study from Harvard-linked researchers has raised concerns about a potential link between HRT use in later life and an increased risk of Alzheimer’s disease. This news is understandably alarming for many women, but before making any drastic decisions, let’s break down what this study really means and how it fits into the broader conversation around menopause management.
The Findings: Should You Be Concerned?
The study (Mass General Brigham, 2024), found that women who started HRT in their 60s and continued into their 70s showed higher levels of tau protein in their brains—one of the key markers associated with Alzheimer’s disease.
However, younger women who used HRT in their 50s and early 60s, and then stopped, did not exhibit the same risk.
This suggests that timing matters when it comes to HRT and brain health. The researchers concluded that starting HRT long after menopause—especially after a decade or more—may contribute to cognitive decline, whereas using it during the early stages of menopause may offer benefits without the same risks.
The Role of Estrogen in Brain Health
Estrogen plays a crucial role in protecting brain cells and reducing inflammation. This is why some studies have previously suggested that early use of HRT may actually protect against cognitive decline. However, as this new research suggests, delayed initiation of HRT may have the opposite effect.
Women naturally have higher levels of tau buildup over their lifetime, which could be linked to the drop in estrogen levels during menopause. This may explain why women are at a higher risk for Alzheimer’s than men.
What Does This Mean for You?
As a menopause coach, my goal is to empower women with the right information so they can make choices that align with their health needs. If you are considering HRT or are already on it, here are some key takeaways:
Timing is critical – The earlier HRT is introduced (within 10 years of menopause), the lower the associated risks.
Personalised treatment matters – Every woman is different. Speak to a menopause specialist to assess your risk factors.
Lifestyle plays a role – A balanced diet, exercise, and brain-supportive habits can help mitigate cognitive risks.
HRT remains a powerful tool for managing menopause symptoms, but it’s not a one-size-fits-all solution. If you’re concerned about cognitive health, have an open discussion with a Menopause Specialist.
The key is informed choices and proactive health management—because menopause is a journey, and every woman deserves to navigate it with confidence and clarity.
