What is menopause?
Menopause is the natural life stage when a woman transitions out of her reproductive years as estrogen levels decline, eventually leading to the end of monthly periods. It most often happens between ages 45 and 55, and the transition can begin several years earlier during perimenopause, when symptoms like hot flashes, sleep changes, and “brain fog” may start.
narration
What are the first signs of menopause?
The first signs of menopause, known as perimenopause, often include:
Sleep disturbances
Hot flashes Night sweats Mood swings
Irregular periods
Some women also experience brain fog, vaginal dryness, or changes in libido. These symptoms can begin several years before periods stop completely.
narration
At what age does menopause usually start?
Menopause typically starts between ages 45 and 55, with the average age in the U.S. being 51. It is officially diagnosed when a woman has gone 12 consecutive months without a menstrual period. Early menopause occurs between the ages of 40 and 45, and premature menopause occurs before the age of 40. These earlier forms of menopause may be influenced by genetics, autoimmune conditions, or medical treatments, including chemotherapy.

Menopause and the brain
Menopause is a major reproductive milestone — but research increasingly shows it’s also a neurological one.As estrogen levels drop, many women experience:
Sleep disruption
Mood changes
Brain fog
night sweats, insomnia, restless sleep
trouble concentrating, forgetfulness, word-finding issues
irritability, anxiety, or low mood
These cognitive shifts aren’t just “in your head.” They’re linked to hormonal changes, disrupted sleep, and even vascular health. And they matter because nearly two-thirds of Alzheimer’s cases are in women.

Expert perspective: What we know about menopause and the brain
Two-thirds of Alzheimer’s cases are women. Scientists still don’t know why the disease disproportionately impacts women and why a drop in estrogen makes the brain more susceptible to neurodegeneration. Tau tangles, a key Alzheimer’s biomarker, also spreads more rapidly in the female brain. Several theories exist, but a 2020 study from Weill Cornell Medicine published in Neurology suggests that the link between Alzheimer’s and menopause could be the answer.
“We understand more now about how hormone replacement therapy, how the pre-menopause transition, how a hysterectomy, for example — all these three things — might not just affect Alzheimer’s risk but really how they affect brain pathology.”

What can help relieve menopause symptoms?
Menopause symptoms can be managed by the following:
- Hormone replacement therapy (HRT)
- Non-hormonal medications, and natural remedies like diet, exercise, and stress reduction.
Treatments should be tailored to individual needs, so it’s best to talk to a doctor about the safest and most effective options.
narration
Hormone replacement therapy (HRT)
About 5 percent of American women opt for hormone replacement therapy — a pill or patch form of therapy to compensate for the hormones lost during menopause. HRT contains natural or synthetic versions of estrogen or sometimes in combination with another hormone called progesterone. Taking HRT within five to 10 years of when menopause starts lowers Alzheimer’s risk, while starting it after age 65 increases it. “The evidence isn’t strong enough to suggest hormone replacement therapy should be taken to prevent Alzheimer’s,” Vaibhav said in a statement.
A study presented at the American Neurological Association’s 2025 conference in Baltimore investigated how the timing of HRT affected Alzheimer’s risk. Study author Dr. Fnu Vaibhav of the Pandit Bhagwat Dayal Sharma University in India conducted a meta-analysis examining more than 50 studies.

Expert perspective: Author Maddy Dychtwald on the different approaches to HRT
Maddy Dychtwald is an entrepreneur and futurist focused on women’s longevity and healthy aging. She is the author of “Ageless Aging: A Woman’s Guide to Increasing Healthspan, Brainspan, and Lifespan” (Mayo Clinic Press, 2023). She spoke to Being Patient about different approaches to hormone replacement therapy (HRT).
“There's two different approaches that are available for taking HRT. The first is just taking a very small amount to tweak my estrogen and progesterone so that I was sleeping okay, that my brain stayed healthy, my heart, my metabolism, my whole systems were still running effectively. That’s what I have chosen to do. However, there is another more aggressive approach. To improve your longevity, you need to take higher doses. That’s not something that you should start in your 60s. If you’re to do it, you need to do it under a doctor’s care, someone who is an expert and who can test you continuously."

Menopause and Alzheimer’s
Is there a link between menopause and Alzheimer disease? Research suggests that hormonal changes during menopause may increase a woman’s risk for Alzheimer’s disease. The drop in estrogen, which supports brain function, may contribute to memory problems and cognitive decline. Early menopause or surgical removal of ovaries may further raise this risk.
