Neuroscience and Menopause: A Scientist’s Personal Story

The first time it happened, I was in front of a team I had run for years. I was about to present, opened my mouth, and could not retrieve a word I’d used my entire career. I sat back down. Finished the meeting. Spent the rest of the day going through everything I knew about neuroscience and menopause transition looking for what was happening to me. I’m a neurobiologist with a PhD, and I have spent years in basic science labs and designing clinical trials. Even with that training, the answers weren’t easy to find. Most of what’s out there is either too vague to act on or scientifically wrong. Ticking Biology is what I built once I stopped waiting for someone else to translate the science.

I Was Trained to Leave Women Out of the Data

To understand neuroscience and menopause today, we need to understand how women were excluded from research for decades.

One of my earliest lessons in research came in graduate school. We were planning an experiment, and my supervisor said: “Order only male mice. We don’t want hormones messing up the results.” It was standard practice across nearly every neuroscience lab on the planet. Female animals were treated as a confounding variable.

My basic science laboratory was not an isolated culture. A 2011 review in Neuroscience & Biobehavioral Reviews found that across 10 fields of biology, neuroscience showed the most extreme male bias: studies using only male animals outnumbered studies using only female animals 5.5 to 1.1 The U.S. National Institutes of Health did not formally require scientists to consider sex as a biological variable until 2016. Before that, “universal” findings about brain function were largely findings about male brain function.4

What that means for women living through perimenopause now: the literature you’re trying to find answers in was, until very recently, not built with you in mind.

Then I Started Losing Words in Meetings

Fast forward two decades. I’m running clinical trials for biotech and biopharma. I’m in my late-forties. I’m watching my own sleep get worse, my recall get worse, and my baseline irritation skyrocket.

The moment it clicked was unglamorous. I was getting up off the bathroom floor with a sharp pain shooting in my knees. The science I’d spent over twenty years studying had to now be applied onto my own body. The same neurochemical systems I had learned in grad school and even designed experiments around were the same systems being destabilized by perimenopausal hormone changes.

It was frustrating when I went looking for solid science aimed at women like me (senior role, peak earning years, cognitive performance non-negotiable), I found mostly wellness advice, supplement advertising, and the vague reassurance that this is “normal.” Normal doesn’t help when your career depends on being the sharpest in the room.

What Neuroscience and Menopause Research Reveal

When you look at perimenopause brain changes through a neuroscientist’s lens, the symptoms stop sounding like personal failures.

Cognitive symptoms (word-finding pauses, slower retrieval, dropped threads in meetings) are not signs that your brain is failing. Estrogen receptors are densely packed in the hippocampus, the prefrontal cortex, and the temporal lobe regions that handle verbal memory. As estrogen fluctuates and declines through perimenopause, those receptor-rich regions change in measurable ways. A 3-year longitudinal imaging study by Lisa Mosconi and colleagues tracked cognitively normal women from premenopause through postmenopause. Compared to age-matched men, the perimenopausal and postmenopausal groups showed faster glucose hypometabolism in the brain, faster hippocampal volume loss, and accelerated declines on estrogen-dependent memory tests.2

Nervous system symptoms (hot flashes, sleep fragmentation, sudden anxiety) are not weakness. They are a sign of a changing biological landscape during the menopause transition. When estrogen levels drop, your body’s internal control center loses its primary stabilizer. Estrogen normally helps fine-tune the brain regions and nerve pathways that manage your “rest-and-digest” and “fight-or-flight” responses. Without steady estrogen, your body’s ability to regulate temperature, stay asleep, and manage stress becomes erratic.

I had to reframe my point of view after learning about perimenopause and menopause science. Brain fog and nervous system instability during perimenopause are not personality changes. They are cell-level adjustments to estrogen levels that fluctuate and decline. The distinction matters because the strategy changes from managing your willpower to targeting the specific biological systems that need support.

Curious Fact: Estrogen receptors are present in nearly every brain region involved in higher cognition, including the hippocampus, prefrontal cortex, and amygdala. When estrogen levels become erratic during perimenopause, every one of those regions is affected.3

Every Article on Ticking Biology Is Based on Peer-Reviewed Research

Every article on Ticking Biology is based on peer-reviewed research and aims to translate menopause science into practical understanding. The alternatives currently flooding the menopause space are anecdotes dressed up as expertise, wellness language mistaken for biological mechanisms, and confident-sounding claims with no studies behind them.

The rules here are explicit. I use peer-reviewed journals only, ranked in the top quartiles by impact (Q1 and Q2). I flag animal research as animal research and small studies as small. Where evidence is mixed or unsettled, I say so.

These rules apply to every article, every YouTube video, and every social post that goes out under the Ticking Biology name.

What Ticking Biology Is For

Ticking Biology is for the woman in her forties or fifties who built her career on her cognitive edge and is now noticing it changing. The one who’s hiding the lapses at work. The one who’s read the wellness content and felt either patronized or alarmed.

This site exists to give that woman the mechanism: what is happening in her brain during the menopause transition, what the evidence says works (and what doesn’t), and how to keep her cognitive edge through a transition the science is only beginning to study in depth.

You don’t need a PhD to understand your own biology. You do need someone willing to translate it without dumbing it down. That’s my job.
