UCLA Expert Offers 10-Year Test to Distinguish Menopause Brain Fog From Dementia

They know. Just ask yourself.
Dr. Voskuhl advises women to trust their own observations of cognitive change rather than dismissing concerns as normal aging.

So the ten-year comparison—is that something a woman can do on her own, or does she need a doctor to help her think through it?

Mimi

Voskuhl frames it as something you can do yourself. You're just asking: What was I like a decade ago? Could I find words easily? Could I multitask? Was my processing speed different? Most people can answer that.

Luke

But there's a real risk here. Memory is unreliable. Someone might misremember how sharp they were ten years ago, or they might be catastrophizing their current state. How much confidence should we have in that self-assessment?

Mimi

That's fair. The ten-year test is a screening tool, not a diagnosis. It's meant to help someone decide whether to seek professional evaluation, not to replace one.

Mark

And what about the women who are already seeing doctors but feel dismissed? What does Voskuhl say about that?

Mimi

She's direct: find another doctor. If your concerns aren't being heard, that's a sign you need a different provider.

Luke

The source mentions that fewer than half of people who notice cognitive decline actually talk to a doctor about it. Do we know why? Is it stigma, or do people assume it's normal aging?

Mimi

The source doesn't dig into that. It just notes the gap exists. But the implication is that many women are suffering in silence, wondering if they're losing their minds.

Mark

And the hormone connection—is that well-established in the research?

Mimi

The source mentions that women experiencing estrogen decline during menopause are particularly affected by brain fog. It's presented as established medical fact, though the article doesn't cite specific studies.

Luke

Right. The article mentions hormone therapy and a 23% lower dementia risk in a headline, but that claim doesn't appear in the body text. We don't know the source of that statistic or how robust it is.

Mark

So the practical takeaway for a woman reading this is: compare yourself to ten years ago, and if you're worse, get evaluated?

Mimi

Yes. And trust your own observations. Don't let a normal test result convince you that nothing has changed if you know something has.

Luke

As long as she understands that self-assessment is a starting point, not a conclusion.

  • Millions of women in perimenopause and menopause face a frightening uncertainty: are their memory lapses a hormonal passage or the first shadow of dementia?
  • Standard neurological tests routinely miss subjective cognitive decline — the very changes patients feel most acutely — leaving women without confirmation or answers.
  • Dr. Voskuhl's ten-year baseline method cuts through that gap, asking women to compare their current mental sharpness to their own remembered peak rather than to a population average.
  • The critical distinction lies in function and trajectory: menopausal fog fluctuates and leaves reasoning intact, while early dementia advances relentlessly and erodes daily independence.
  • Women are urged to pursue full evaluations — MRIs, vascular and thyroid screenings — while also being told plainly: if a doctor dismisses your concerns, find another one.

Somewhere in midlife, millions of women begin to quietly question their own minds — wondering whether the fog settling over their thoughts is a passage or a warning. At a women's health summit in New York, UCLA neurologist Dr. Rhonda Voskuhl offered a grounding insight: the most reliable diagnostic tool may not be a clinical test, but a woman's own memory of who she was a decade ago. In a medical landscape that often fails to capture what patients feel but tests cannot measure, this call to trust one's inner baseline is both a clinical recommendation and an act of restoration.

A woman in her fifties forgets why she walked into a room. She loses a word she has known her whole life. The question that follows is one of the most unsettling a person can ask: Is this the beginning of dementia, or is it something else?

Dr. Rhonda Voskuhl, a neurology professor at UCLA, has spent years helping women navigate that question. At the Livelong Women's Health Summit in New York City, she offered a tool that is both simple and profound: look back ten years. Recall what your mind was like then. If you were sharper, faster, more fluid — that contrast is your baseline, and it matters more than most clinical tests will tell you.

This is because standard neurological evaluations frequently miss what medicine calls subjective cognitive decline — changes a patient experiences clearly but that don't register on conventional measures. The CDC estimates roughly one in nine American adults report this kind of decline, yet fewer than half ever raise it with a physician. Voskuhl compared it to an NFL player who tells his doctor he feels weaker, only to be told his test results are fine. The player knows his own body. Women, she argued, know their own minds — and that knowledge deserves to be honored.

The difference between menopausal brain fog and early dementia comes down to function and direction. Menopausal fog is temporary and inconsistent — words slip, processing slows, focus scatters — but reasoning holds and independence remains. Early dementia is cumulative and relentless, gradually overtaking the ability to manage finances, navigate familiar places, or make sound decisions. One fluctuates; the other advances.

Voskuhl recommends a full medical workup — brain MRIs, vascular screenings, thyroid panels — to rule out treatable causes. But above all, she urges women to trust what they already sense about themselves. If a doctor dismisses those concerns, her advice is direct: find another doctor. The ten-year test is not a diagnosis. It is permission to take yourself seriously.

A woman in her fifties walks into a room and forgets why she came. She loses a word mid-sentence that she has known her whole life. She misplaces her keys. These moments arrive with enough frequency that she begins to wonder: Is this early dementia? Is this Alzheimer's creeping in? Or is it something else entirely?

Dr. Rhonda Voskuhl, a neurology professor at UCLA and co-founder of Cleopatra RX in Los Angeles, has spent years helping women answer that question. The answer, she says, often lies not in a neurological test but in a woman's own memory of herself. At the Livelong Women's Health Summit in New York City, Voskuhl offered a deceptively simple tool: look back ten years. Ask yourself what your mind was like then. Were you forgetting words? Struggling to multitask? Processing information more slowly? If the answer is no—if you were sharper then than you are now—you have a baseline. You have something to measure against.

This matters because standard neurological tests frequently miss what doctors call subjective cognitive decline: changes that a patient notices and feels acutely, but that don't show up on conventional testing. The Centers for Disease Control and Prevention reports that roughly one in nine American adults report subjective cognitive decline, yet fewer than half of them ever mention it to a doctor. The gap between what a person knows about themselves and what a test can confirm is real and consequential.

Voskuhl illustrated the problem with an analogy. Take an NFL player who tells his doctor he feels weaker than he used to be. The doctor runs standard strength tests and finds nothing wrong. "Oh no, you're still strong," the doctor says. But the player knows his own body. He knows what peak performance felt like. He can feel the difference. The same principle applies to the brain. Women often recognize when their cognitive abilities have shifted from their own baseline, and that recognition deserves to be taken seriously.

The distinction between menopausal brain fog and early dementia hinges on function and progression. Menopausal brain fog—tied to the estrogen decline of perimenopause and menopause—typically produces temporary, scattered lapses: you misplace something, you grope for a word, your processing slows down. Your reasoning remains intact. Your independence is not threatened. The symptoms fluctuate, often worsening with stress or poor sleep. Early dementia, by contrast, is relentless and cumulative. Memory loss persists and worsens. It interferes with concrete daily tasks: managing finances, navigating familiar routes while driving, making sound judgments. It does not come and go. It advances.

When cognitive concerns arise, Voskuhl advises women to seek a full medical evaluation—brain MRIs, vascular screenings, thyroid testing—to rule out treatable conditions like blood vessel disease or hormonal imbalance. But before that evaluation, and during it, women should trust what they know about themselves. "They know," Voskuhl said. "Just ask yourself." And if a doctor dismisses those concerns, she offered blunt guidance: find another doctor. The ten-year test is not a diagnosis. It is permission to listen to yourself.
