There is no proven way to prevent Alzheimer’s disease. You can still take practical steps to support your overall health and address some factors associated with dementia risk. Treat them as worthwhile health measures—not as a guarantee against Alzheimer’s or a substitute for medical care.
Can Alzheimer’s disease be prevented?
Not with any method proven to work. Alzheimer’s-related brain changes may begin years before symptoms, but that does not mean an individual can predict or control whether the disease will develop. Age is an established risk factor that cannot be changed; family history, genes, environment and lifestyle can also contribute. The APOE ε4 gene variant is associated with increased Alzheimer’s risk in some populations, but genetic risk is not destiny.
The World Health Organization’s second-edition dementia-risk-reduction guideline, published July 15, 2026, covers adults without dementia, including people with normal cognition and those with mild cognitive impairment. It addresses healthy behaviours, associated health conditions, environmental exposures and tailored interventions involving multiple areas. Its overview also identifies evidence gaps. That broad scope is not a promise that any one action prevents Alzheimer’s.

Which everyday health steps are reasonable?
Prioritize measures with benefits for health beyond dementia. Evidence varies by action and outcome, and an association with lower risk is not the same as proof that a measure prevents Alzheimer’s.

Manage blood pressure and other chronic conditions
If you have high blood pressure, discuss a management plan with a healthcare professional. Also seek appropriate care for diabetes and other chronic health conditions. Do not change or stop medication, or set a new blood-pressure target, based on dementia-prevention claims.
The National Institute on Aging (NIA) summarizes SPRINT-MIND, a trial of more than 8,000 adults aged 50 and older at high cardiovascular risk. In that population, intensive treatment targeting systolic blood pressure below 120 mmHg, compared with a standard target below 140 mmHg, significantly reduced the risk of mild cognitive impairment (MCI); brain scans also showed slower buildup of white matter lesions. Those were trial targets and outcomes—not a universal home target or an instruction to intensify treatment. The NIA notes that observational findings on blood pressure and dementia are mixed, and that more research is needed to understand how age and cardiovascular risk affect the relationship. Its summaries discuss observational studies involving more than 17,000 adults and approximately 31,000 adults across six community-based cohorts, but those sample sizes alone do not establish a prevention effect.

A 2017 National Academies review, as summarized by the NIA, found “encouraging but inconclusive” evidence for managing high blood pressure, increasing physical activity and cognitive training. It said further trial evidence was needed to determine whether these interventions prevent or delay Alzheimer’s, MCI or cognitive decline.

Stay physically active
Make regular physical activity part of your routine if it is appropriate for your health and abilities. The NIA describes its evidence for increased activity as promising but inconclusive for preventing or delaying Alzheimer’s, MCI or cognitive decline. Ask a clinician for guidance if you have health concerns that affect what activity is safe for you.

Eat a balanced diet, and avoid smoking and harmful alcohol use
A balanced diet and avoiding tobacco and harmful alcohol use are sensible ways to support general health. Do not treat a particular food plan as a proven Alzheimer’s preventive treatment. The WHO’s 2019 guideline summary recommended a Mediterranean-like diet for risk reduction, but it predates the WHO’s second edition from 2026 and should not be presented as the detailed recommendation of that newer edition.
Address sleep, hearing and mood concerns
Seek care for sleep problems, hearing loss or mood symptoms on their own merits. A clinician can help assess potential causes and discuss suitable care; the evidence here does not establish that treating any one of these concerns prevents Alzheimer’s.

For hearing specifically, an NIA report on research progress in 2024 described a trial with three years of follow-up in which hearing aids appeared to reduce cognitive decline among older adults with particular risk factors, but not among participants without those risk factors. The finding is not evidence that hearing aids prevent Alzheimer’s or that every person will receive a cognitive benefit.

- Supplements: No supplement or vitamin combination is established here as an Alzheimer’s preventive treatment. The WHO’s 2019 guideline summary advised against certain vitamin and supplement combinations for dementia-risk reduction; do not assume that older guidance supplies the detailed recommendations of the 2026 edition.
- Brain games and cognitive training: The NIA describes cognitive-training evidence as encouraging but inconclusive for preventing or delaying Alzheimer’s, MCI or cognitive decline. A game or app should not be sold as a proven preventive treatment.
- Single “brain-health” diets, devices or protocols: No single diet, device or treatment is proven here to prevent Alzheimer’s. Be wary of claims that promise prevention or ask you to replace appropriate care.
- Blood-pressure targets promoted without context: The SPRINT-MIND comparison involved a defined trial population and clinician-managed treatment. It does not mean that everyone should aim for systolic pressure below 120 mmHg.
The 2019 WHO guideline summary also found insufficient evidence to recommend social activity as a dementia-risk-reduction intervention. That is not a reason to avoid social connection; it means the summary did not establish it as a preventive intervention.

How can you make a practical plan?
- Start with your health history. Make a list of conditions, medications and concerns—such as high blood pressure, diabetes, hearing loss, sleep problems or mood symptoms—to discuss with a healthcare professional.
- Agree on safe, relevant changes. Ask which steps suit your health and abilities, including blood-pressure management and physical activity. Do not start, stop or adjust medication without professional guidance.
- Choose sustainable habits. Focus on routine activity, balanced eating, avoiding smoking and harmful alcohol use, and getting appropriate care for health problems rather than buying a product that promises Alzheimer’s prevention.
- Reassess with your clinician. Review your health needs and plan over time. A healthy routine can support well-being without guaranteeing that Alzheimer’s will not develop.
