Hormone Therapy After 60 and Brain Health: What We Know—and What We Don’t

Dr. Heidi Queen, MD | Energize Health & Hormones

At Energize Health and Hormones, Dr. Heidi Queen often sees women who are doing exactly what we hope they will do at this stage of life: asking thoughtful questions about long-term health. Not just how to feel better today—but how to protect memory, independence, and cognitive function for years to come. It’s a natural evolution of the hormone conversation.

Once symptoms like hot flashes and night sweats settle, a new question tends to emerge: Can hormone therapy help protect the brain? And more specifically, is it worth starting—or continuing—after 60 for that reason alone? Recent research helps clarify the answer. But perhaps more importantly, it helps explain why there’s still so much confusion.

A Closer Look at the Latest Research

A recent systematic review and meta-analysis in The Lancet Healthy Longevity took a careful look at menopause hormone therapy (MHT) and its relationship to mild cognitive impairment and dementia. What sets this analysis apart is its rigor. Instead of pulling from every available study, researchers limited their review to higher-quality evidence—randomized controlled trials and well-designed prospective studies where women were followed over time. Out of a much larger pool, only 15 studies met the criteria for review, and just 10 were strong enough for meta-analysis.

That alone tells us something important: when it comes to hormone therapy and brain health, the highest-quality data is still relatively limited. And the conclusion? There is no clear evidence that hormone therapy either reduces or increases the risk of dementia. Not exactly the headline many people expect—but it’s a meaningful finding.

Why the Message Feels So Mixed

If you’ve spent any time reading or listening to conversations about hormones and brain health, you’ve probably heard more definitive claims. Some suggest hormone therapy is protective. Others warn of risk. Still others describe it as essential. So how can all of these perspectives exist at once? The answer lies in the quality of the data.

Some earlier studies—particularly observational ones—have suggested a possible benefit, especially with estrogen-only therapy. But these types of studies are more prone to bias. They often rely on less precise data (like self-reported hormone use), may not account for timing or formulation, and can unintentionally overestimate benefits. When researchers narrow the lens to include only the most reliable study designs, the signal becomes much less clear.

In other words: the more carefully we look, the more uncertainty we find. And while that might feel frustrating, it’s actually how good science works.

What About the Women’s Health Initiative?

One of the only randomized trials to specifically examine dementia risk—the Women’s Health Initiative Memory Study (WHIMS)—did find an increased risk of dementia in women who started certain forms of oral hormone therapy after age 65. However, context matters here.

The formulations used in that study (such as oral conjugated estrogens and medroxyprogesterone) are not the same as many of the therapies commonly used today. In addition, starting hormone therapy after age 65 is very different from beginning closer to menopause and continuing thoughtfully over time. So while WHIMS remains an important piece of the puzzle, it doesn’t fully answer the question for modern hormone therapy approaches.

The Brain Is Not “Failing” in Menopause

One of the more concerning trends in recent years has been the rise of dramatic messaging around menopause and brain health—particularly on social media. Claims that the brain is “degenerating” or “eating itself” without hormone therapy are not supported by credible evidence. What we do know is that the brain undergoes metabolic and hormonal shifts during menopause. But these changes reflect adaptation, not collapse.

Understanding that distinction matters. Because fear-based messaging can push women toward decisions that aren’t grounded in evidence—or away from options that might genuinely help them.

What This Means for Hormone Therapy After 60

So where does this leave us? At this point, hormone therapy should not be prescribed specifically for the prevention of dementia. The data simply isn’t strong enough to support that use. But that doesn’t mean hormone therapy has no place in this stage of life. As discussed in our earlier article, hormone therapy after 60 or even 65 can still be appropriate for many women—especially when used to support:

• Quality sleep
• Mood and emotional stability
• Bone health
• Muscle mass and physical resilience
• Urogenital health and comfort

In other words, the role of hormones remains meaningful—it’s just not a proven strategy for preventing cognitive decline.

What Actually Supports Brain Health?

One of the more practical takeaways from this conversation is this: while hormone therapy remains uncertain in this area, there are well-established ways to support cognitive health over time. These tend to be less flashy—but far more reliable:

• Consistent physical activity, especially strength training
• Cardiovascular health and blood sugar balance
• Quality sleep
• Cognitive engagement and social connection
• Limiting alcohol and addressing inflammation

These are the interventions that continue to show up, again and again, in high-quality research on brain health and dementia prevention.

The Value of Individualized Guidance

If there’s one theme that continues to emerge—both in the research and in clinical practice—it’s that there is no universal answer. At Energize Health and Hormones, Dr. Queen works with women to sort through exactly these kinds of questions. Not in a rushed or one-size-fits-all way, but through a collaborative process that considers personal history, current symptoms, long-term goals, and evolving research.

For some women, hormone therapy remains an important part of that picture. For others, the focus may shift toward different strategies for supporting cognitive and overall health. The key is clarity—not confusion.

Moving Forward with Confidence

The conversation around hormone therapy and brain health is still evolving. And while it would be comforting to have a simple, definitive answer, the reality is more nuanced. We don’t have strong evidence that hormone therapy prevents dementia. We don’t have strong evidence that it causes it when used appropriately, either. What we do have is an opportunity—to make informed, individualized decisions based on the best available data.
