Alzheimer’s Prevention for Women: 14 Ways to Support Brain Health During Midlife
Why Brain Health Matters for Women
If you are a woman reading this, here is an important statistic to know: a woman’s estimated lifetime risk of developing Alzheimer’s disease at age 65 is 1 in 5. By the year 2050, this figure is expected to double.
That number is not meant to create fear. It is a reminder that brain health deserves attention long before symptoms begin.
At EverThrive Nutrition we believe nutrition and lifestyle habits play a powerful role in healthy aging, especially during perimenopause and menopause.
The encouraging news? Research consistently shows there are evidence-based ways to help reduce dementia risk and support long-term cognitive health.
Why Women Are at Higher Risk for Alzheimer’s Disease
Nearly two-thirds of Americans living with Alzheimer’s are women. Researchers believe several factors contribute to this increased risk, including:
· Longer life expectancy
· Hormonal shifts during perimenopause and menopause
· Declining estrogen levels
· Changes in brain metabolism
· Increased inflammation and vascular changes during midlife
Estrogen appears to help protect brain health, which is why the menopause transition is increasingly recognized as an important window for prevention and early intervention.
Non-Modifiable Alzheimer’s Risk Factors
Some risk factors cannot be changed, but understanding them can help you take a more proactive approach to brain health.
Non-modifiable risk factors include:
· Age, especially after 65
· Genetics and family history
· Carrying the APOE-e4 gene
· Female sex
· Race and ethnicity, with higher dementia rates seen in Black and Hispanic Americans
Awareness is not about fear. It is about focusing your energy on the factors you can influence.
14 Modifiable Risk Factors for Dementia
In 2024, the The Lancet Commission released updated research estimating that addressing key lifestyle and health factors could prevent or delay up to 45% of dementia cases worldwide.
The report identified 14 modifiable risk factors for dementia and Alzheimer’s disease:
1. Less education in early life
2. Hearing loss
3. High LDL cholesterol
4. Depression
5. Traumatic brain injury
6. Physical inactivity
7. Diabetes
8. Smoking
9. Hypertension
10. Obesity
11. Excessive alcohol use
12. Social isolation
13. Air pollution
14. Untreated vision loss
Two newer additions — high LDL cholesterol and untreated vision loss — highlight how deeply connected overall health and brain health truly are.
Additional Alzheimer’s Prevention Factors Researchers Are Studying
Beyond the Lancet report, emerging research continues exploring how the following may influence cognitive decline:
· Chronic stress
· Poor sleep quality
· Insulin resistance
· Gut health
· Omega-3 fatty acid intake
· B vitamin deficiencies
· Vitamin D deficiency
· Early menopause or surgical menopause
· Hormone therapy timing
Practical Ways to Support Brain Health During Midlife
The goal is not perfection. Consistent habits matter most.
1. Exercise Regularly
Physical activity supports:
· Healthy blood flow to the brain
· Blood sugar regulation
· Cardiovascular health
· Reduced inflammation
Even regular walking can have meaningful long-term benefits for cognitive health.
2. Prioritize Protein and Fiber at Meals
Balanced blood sugar plays an important role in brain health.
Focus on:
· Protein at every meal
· Fiber-rich carbohydrates
· Healthy fats
· Omega-3-rich foods like salmon, walnuts, and chia seeds
This is one of the foundational nutrition strategies we emphasize at EverThrive Nutrition.
3. Protect Your Hearing and Vision
Hearing loss and untreated vision changes are two of the most overlooked (and most treatable) dementia risk factors.
Focus on:
· Routine hearing screenings
· Annual eye exams
· Wearing hearing aids if recommended
· Updating corrective lenses when needed
4. Stay Socially Connected
Social isolation is strongly associated with increased dementia risk.
Protective habits include:
· Maintaining friendships
· Participating in community groups
· Staying connected with family
· Joining volunteer or faith communities
5. Monitor Blood Pressure and Cholesterol
Heart health and brain health are closely connected.
Especially during perimenopause and menopause, work with your healthcare provider to monitor:
· Blood pressure
· LDL cholesterol
· Blood sugar
· Triglycerides
6. Improve Sleep Quality
Deep sleep helps the brain clear metabolic waste, including amyloid proteins associated with Alzheimer’s disease.
Support better sleep by:
· Keeping consistent sleep and wake times
· Getting morning sunlight exposure
· Limiting screens before bed
· Reducing alcohol intake at night
7. Limit Alcohol and Avoid Smoking
Both smoking and excessive alcohol use are associated with increased dementia risk and chronic inflammation.
Reducing these exposures can support both brain and overall health.
8. Support Your Mental Health
Depression is one of the strongest modifiable risk factors for cognitive decline.
Seeking support through therapy, counseling, stress management, or medical care is an important investment in long-term wellness.
The Bottom Line on Alzheimer’s Prevention for Women
Brain health is not built through one perfect choice. It is shaped by small, sustainable habits practiced consistently over time.
If you are navigating perimenopause or menopause and want support for your brain health, metabolism, energy, and overall wellness, this is exactly the work we love doing at EverThrive Nutrition.
Our individualized nutrition counseling and Thrive Forward program are designed to help women build realistic, evidence-based habits that support healthy aging from the inside out.
