The most reliable ways to prevent Alzheimer’s, or at least lower your risk and delay it, are the same habits that protect your heart and overall health: keep your blood pressure, blood sugar and cholesterol in a healthy range, stay physically active, treat hearing and vision loss, do not smoke, drink little or no alcohol, protect your head, sleep well, look after your mood, stay socially connected and keep learning. No step offers a guarantee, but together they target many of the risk factors researchers have linked to dementia.
Below are 12 practical ways to put that into action, grouped by what each one protects. You do not need to tackle them all at once. Pick two or three that feel achievable, build them into your week and add more over time.
Protect Your Blood Vessels
The brain uses a large share of the body’s blood supply, and damage to its small vessels contributes to memory decline. Vascular health is one of the strongest themes in dementia research.
1. Know and control your blood pressure
High blood pressure in midlife is one of the best-documented risk factors for dementia. Check it regularly, including at home, and follow your doctor’s plan if it is high.
2. Manage blood sugar and cholesterol
Type 2 diabetes and high LDL cholesterol are both linked to higher dementia risk. Routine screening catches problems early, when they are easiest to address.
3. Do not smoke
Smoking damages blood vessels throughout the body. Quitting at any age brings benefits, and free help is available at 1-800-QUIT-NOW.
Protect Your Senses
4. Treat hearing loss
Hearing loss is among the largest modifiable dementia risk factors identified by the 2024 Lancet Commission. Researchers think straining to hear may tax the brain and lead to social withdrawal. Get a hearing test and use hearing aids if recommended.
5. Take care of your eyes
Untreated vision loss was added to the list of dementia risk factors in 2024. Regular eye exams and treatment for problems such as cataracts help keep you engaged with the world.
Protect Your Head
6. Prevent head injuries
Wear a seat belt, use helmets for biking and other sports, and reduce fall risks at home with good lighting, secure rugs and grab bars. Serious and repeated head injuries are linked to later dementia.
7. Limit alcohol
Heavy drinking is associated with brain damage and higher dementia risk. If you drink, keep it low, and talk to your doctor if cutting back is hard.
Move and Nourish Your Body
8. Stay physically active
Aim for at least 150 minutes of moderate activity a week, such as brisk walking, plus muscle strengthening twice a week. Exercise supports blood flow, mood, sleep and weight all at once.
9. Eat a brain-friendly pattern
The MIND diet blends Mediterranean and DASH principles, emphasizing leafy greens, other vegetables, berries, nuts, beans, whole grains, fish, poultry and olive oil, with less red meat, butter, sweets and fried food. A healthy weight in midlife also lowers risk.
Rest, Mood and Connection
10. Sleep well and treat sleep disorders
Good sleep supports memory, and loud snoring with breathing pauses can signal sleep apnea, which is treatable. Ask your doctor if you wake up tired despite enough hours in bed.
11. Look after your mental health
Depression is linked to higher dementia risk. Treatment through therapy, medication or both can improve mood and may help protect thinking.
12. Stay social and keep learning
Social isolation is a recognized risk factor, and mental challenge builds cognitive reserve. Volunteer, join a club, take a class, learn an instrument or teach someone a skill.
Myths Versus Facts
| Myth | What the evidence says |
|---|---|
| If it runs in my family, nothing I do matters | Genes raise risk, but healthy habits still matter for people with a family history |
| Memory loss is a normal part of aging | Mild slowing is common, but dementia is not a normal part of aging |
| A single superfood can prevent Alzheimer’s | Overall eating patterns matter more than any one food |
| Brain games alone will protect me | No single game is proven to prevent Alzheimer’s; varied learning and social activity are better bets |
| Aluminum pans cause Alzheimer’s | Research has not confirmed this link, according to the Alzheimer’s Association |
When to See a Doctor
Prevention is about the future, but your present matters too. It helps to know your own baseline, so keep track of how you are doing and mention any changes at your yearly checkup. New memory problems, such as repeating questions, misplacing things in odd places, trouble following conversations or getting lost on familiar routes, should be checked by a doctor. Many causes, including medication side effects, thyroid problems, vitamin deficiencies and depression, can be treated. If someone shows sudden confusion, facial drooping, arm weakness or slurred speech, call 911 right away.
Frequently Asked Questions
What is the number one way to prevent Alzheimer’s?
No single habit stands far above the rest, but regular physical activity and good blood pressure control are frequently highlighted because they affect many other risk factors at once.
Is it ever too late to start?
No. Benefits for the heart, mood and overall health begin at any age, and research suggests risk factors matter throughout life.
Can vitamins prevent Alzheimer’s?
No vitamin has been proven to prevent Alzheimer’s. Correcting a real deficiency, such as low vitamin B12, is important for thinking, so ask your doctor about testing.
