"I lost the word for refrigerator." That was how she opened the conversation.
Adele is 51. Freelance editor, longtime friend of a friend, the woman in her circle who reads three books a week and remembers every birthday.
She had been on the phone with a client she has worked with for eight years. Mid-sentence, the word for the appliance her husband was standing in front of just disappeared.
"I said 'the cold box in the kitchen' three times before we both started laughing," she told me. "Then I sat in my car afterward and did not laugh."
Know that feeling? The one where a small moment lands harder than expected, because you are not sure what it means.
Estrogen has receptors throughout the brain, especially dense in the hippocampus and prefrontal cortex. That is memory formation and executive function, side by side.
For decades, estrogen has been supporting verbal fluency, working memory, and the glucose metabolism that fuels neurons. When it fluctuates in perimenopause, those systems fluctuate too.
Word-finding pauses, forgetting why you walked into a room, losing your thread mid-sentence; all of it becomes more common. Research from Weill Cornell Medicine has documented these cognitive shifts as real, measurable, and often resolving as the brain adapts to its new hormonal baseline.
Think of estrogen as the electricity to a house that has been fully wired for years. When the current flickers, the lights flicker too, even though the wiring is intact.
There is another layer to this picture worth understanding. The brain does not run in isolation from the body that feeds it.
What you eat directly influences the fuel available to neurons, the inflammation levels in brain tissue, and the blood sugar swings that make foggy thinking sharper or worse. Two women with identical hormonal changes can have very different cognitive experiences based on what is on their breakfast plate that morning.
That is why researchers who study cognitive aging keep circling back to nutrition. Not as a cure, but as one of the few levers a woman can pull consistently, meal after meal, that her brain notices.
I am sharing Adele's story because she came to me thinking she was losing her mind. She was not, and if you have had your own refrigerator moment, neither are you.
Cognitive shifts in perimenopause are among the most common experiences women bring to their doctors, and among the most dismissed. Your brain is not broken, and your experience deserves to be taken seriously by the people whose job it is to listen.
Two things that fit a real life.
🛏️ Protect your sleep with the same seriousness you would protect an important meeting, because deep sleep is when the brain clears metabolic waste and consolidates the day's memories into longer-term storage.
🍳 And build breakfasts around protein, fiber, and healthy fats rather than fast carbohydrates and sweetened coffee drinks. Blood sugar stability through the morning has a direct and measurable effect on how sharp your thinking feels by 11am, and it costs nothing extra to arrange.
If your memory changes are progressing quickly, interfering with work you have handled easily for years, or accompanied by confusion about time, place, or familiar faces, see your doctor and ask specifically about a cognitive screening. Perimenopausal fog and early cognitive disease look different to a trained clinician, and it is worth having a professional draw that line for you rather than sitting alone with the question.
You are not losing yourself. You are moving through a well-documented biological transition that has a beginning, a middle, and an end.
We are navigating it together.
