Women’s Alzheimer’s Risk: Why It’s Higher Than Men’s
The Silent Link: How Hormonal History May Increase Alzheimer’s Risk in Black Women

For Angeleta Cox, the vibrant memories of her mother, Sonia elizabeth Cox, are now intertwined with a growing understanding of a potential link between hormonal health and Alzheimer’s disease. Sonia passed away in late 2024 after a years-long battle with the disease, and Angeleta’s journey through grief has led her to uncover crucial information about risk factors, especially for Black women. This is her story, and a call for greater awareness and research.
A Mother’s Legacy and a Daughter’s discovery
Angeleta remembers her mother as a force of nature - a dedicated gardener, a loving presence, and the heart of their family. Watching Sonia slowly succumb to Alzheimer’s was devastating. But through the pain, Angeleta began to piece together a pattern, a potential connection that researchers are only beginning to fully explore.
Looking back,Angeleta now realizes her mother’s surgically induced menopause,following a hysterectomy for fibroids in her 30s,may have been a significant risk factor. “It wasn’t something we considered at the time,” she says. “we just knew she needed the surgery to address the fibroids and improve her quality of life.”
Fibroids,noncancerous growths in the uterus,disproportionately affect Black women. While hysterectomies are a common treatment, the resulting surgical menopause - the abrupt cessation of ovarian function – can have long-term health consequences. And increasingly, research suggests a possible link to increased Alzheimer’s risk.
The Hormonal Connection to Alzheimer’s: What we certainly know
Alzheimer’s disease is a complex condition with no single cause. However, a growing body of evidence points to hormonal fluctuations, particularly those experienced during menopause, as a potential contributing factor, especially in women.
Estrogen, such as, plays a vital role in brain health, supporting cognitive function and protecting against neurodegeneration. The dramatic decline in estrogen levels during menopause can impact these protective mechanisms. Surgical menopause, by abruptly removing the primary source of estrogen, may amplify these effects.
“We’re learning that the timing of menopause – whether natural or surgical – can be really vital,” explains Dr. Lisa Barnes, a leading researcher in Alzheimer’s and women’s health at Rush University Medical center (though not directly involved in Angeleta’s case). “Early or surgically induced menopause is associated with a higher risk of cognitive decline and dementia later in life.”
The reasons are multifaceted. Estrogen influences cerebral blood flow, glucose metabolism in the brain, and the production of amyloid plaques – a hallmark of Alzheimer’s disease. moreover, the vascular system and the brain are closely linked, and hormonal changes can impact vascular health, increasing the risk of stroke and other conditions that contribute to cognitive decline.
Why Black Women May Be at Higher Risk
The potential link between hormonal health and Alzheimer’s is particularly relevant for Black women, who are disproportionately affected by both fibroids and Alzheimer’s disease. Black women are diagnosed with Alzheimer’s at higher rates than white women, and often at a younger age.
Several factors contribute to this disparity:
Higher Fibroid Prevalence: Black women experience fibroids more frequently, severely, and at an earlier age than women of other racial groups. this often leads to earlier hysterectomies and, consequently, earlier surgical menopause.
Chronic Stress & Systemic Racism: The chronic stress associated with systemic racism and socioeconomic disparities can disrupt hormonal balance and contribute to inflammation, both of which are linked to increased Alzheimer’s risk.
Limited Access to Healthcare: Disparities in healthcare access can lead to delayed diagnosis and treatment of both fibroids and Alzheimer’s, exacerbating the problem.
Genetic Predisposition: Emerging research suggests potential genetic factors that may increase Alzheimer’s risk in African Americans.
Making Different Choices and Sharing the Knowledge
Angeleta’s newfound understanding has profoundly impacted her own health choices. ”When it came time for me to deal with my fibroids, I chose not to have a full hysterectomy,” she shares. She explored alternative treatment options to preserve her hormonal health.
