As hormones shift in midlife, brain, metabolic and cardiovascular health can change too – prompting a rethink of women’s healthcare.
Menopause has largely been framed around what happens to reproduction. Hot flashes, irregular periods and fertility mark the transition, while the rest of the body is often treated as if it is simply expected to get on with things. But what if that framing has been too narrow all along?
In the latest episode of Longevity.Technology UNLOCKED, hosted by CEO Phil Newman, neurologist Dr David Dodick and gynecologist Dr Elizabeth Poynor make the case for looking at menopause as something much bigger: a neurological, metabolic and cardiovascular transition that can begin reshaping a woman’s health before she even realizes she has entered perimenopause. The brain is not sitting outside the hormonal system; it is part of it.
The brain changes before menopause arrives
Poynor explains that estrogen receptors are distributed throughout the body, with particularly important concentrations in areas of the brain including the hippocampus, hypothalamus and prefrontal cortex.
As estrogen begins to fluctuate during midlife, those changes can affect how the brain uses energy. Estrogen helps the brain use glucose, while also supporting mitochondrial function – essentially helping the cells’ tiny power stations keep producing the energy they need. When that system changes, the effects can feel surprisingly ordinary: forgetting a word, struggling to concentrate, sleeping badly or suddenly feeling unlike yourself.
Brain fog is often dismissed as an inevitable inconvenience of getting older. However, Poynor describes it as something more biologically meaningful, particularly because the brain eventually adjusts as hormone levels stabilize. The same hormonal fluctuations can also affect the hypothalamus, which helps regulate body temperature, contributing to hot flashes and night sweats. Sleep can suffer too, creating another potential knock-on effect for brain health. The result is less a collection of unrelated symptoms than a chain reaction.
When migraine becomes a clue
That connection becomes even more interesting when migraine enters the picture. Dodick notes that migraine affects women disproportionately, with hormonal changes playing a major role across the reproductive lifespan. For some women, perimenopause can bring a dramatic increase in migraine frequency and severity. That makes migraine potentially more than an isolated neurological condition. In the context of midlife hormonal change, it can become another signal that the body is moving through a larger transition. Dodick argues that the medical system should respond accordingly.
“I think everyone, including physicians, should think about menopause or perimenopause as not just a reproductive transition or a female hormone transition, but a neurological and a cardiometabolic transition,” he added.
It is a deceptively simple shift in language, but it changes what doctors might look for.
The metabolic piece is impossible to ignore
As estrogen fluctuates, Poynor explains, body fat can shift towards visceral fat, the fat surrounding internal organs. At the same time, muscle mass naturally declines with age, while insulin resistance can become more pronounced. That matters for the brain because metabolism and cognition are not separate worlds. Insulin resistance, inflammation and changes in brain energetics can interact with the effects of declining estrogen.
Dodick describes the convergence as a “triple whammy”: the brain is aging while cardiometabolic risk factors rise and estrogen is changing. There is also a social dimension that is harder to measure but impossible to ignore. Midlife can coincide with intense professional pressure, caregiving responsibilities and family transitions. Poynor points to the way brain fog can affect confidence at precisely the moment many women are reaching senior positions.
“One of my friends said to me one day, it was so interesting. She says, ‘I spent my whole life trying to get to be the head of the board table, I finally got there and I couldn’t remember my name,’” she said.
It is funny in the way uncomfortable truths can be funny, but the underlying issue is serious: symptoms that are biological can become professional, psychological and economic consequences.
Beyond the one-size-fits-all menopause conversation
The discussion around menopausal hormone therapy is where the conversation becomes particularly nuanced. Poynor and Dodick point to evidence suggesting that timing matters. Some research has raised concerns about starting certain hormone therapies later in life, while observational evidence has suggested potential brain-health benefits when treatment begins closer to the menopausal transition. But the evidence is not definitive, and the treatments studied in older trials do not always resemble the therapies commonly used today. That uncertainty is precisely why both doctors argue against treating age alone as the deciding factor.
Dodick compares the emerging approach to assessing a car: its structure, its internal systems and, ultimately, how it performs on the road. Brain imaging, blood biomarkers, metabolic measurements and cognitive assessments can potentially provide a more detailed picture than a single hormone measurement ever could.
“The likelihood that that’s true for every individual, right, is approaches zero,” he says of blanket treatment rules.
That may be the most important point of the conversation. Personalization should not mean giving everyone more tests or more treatments. It should mean asking better questions about the individual in front of you. And perhaps that is where women’s health has the most room to evolve: not by turning menopause into another longevity optimization project, but by finally treating the transition as consequential enough to deserve integrated, evidence-led care.
As Dodick puts it, “there is no longevity without brain health.” The challenge now is making that understanding useful beyond specialist clinics and ensuring that the knowledge being generated reaches the women who need it most.
