Dementia is not a normal part of aging, and research shows that many cases can be prevented or delayed. According to the 2024 Lancet Commission on Dementia Prevention, Intervention, and Care, addressing key lifestyle and health factors could prevent or delay up to 40% of dementia cases worldwide.
Never Too Early, Never Too Late
It’s never too early to start protecting your brain, and never too late to make a difference.
At any age, making healthy changes can improve brain function, support memory, and reduce your risk of dementia.
Every step counts — big or small!
Midlife Risk Factors (ages 40–65)
1
Hearing Loss
Avoid loud noise, use hearing protection, and wear hearing aids if needed.
2
Traumatic Brain Injury (TBI)
Protect your head during sports or activities with a risk of falls or impact.
3
High Blood Pressure (Hypertension)
Check your blood pressure regularly and keep it in a healthy range.
4
Obesity
Maintain a healthy weight through a balanced diet and physical activity.
5
Diabetes
Manage your blood sugar through healthy eating, exercise, and medications if prescribed.
6
Excessive Alcohol Use
Choose low-alcohol or non-alcoholic options. Limiting alcohol protects brain and body health.
7
LDL Cholesterol (“Bad” Cholesterol)
High LDL cholesterol can block blood flow to the brain. Eat heart-healthy foods and talk to your doctor about testing and treatment.
8
Vision Loss
Get regular eye exams and correct vision problems early. Good vision helps you stay engaged and active.
Later-Life Risk Factors (ages 65+)
9
Depression
Care for your mental health and seek help early if you feel low or lose interest in activities.
10
Smoking
Quit smoking and avoid secondhand smoke. Both increase the risk of dementia.
11
Social Isolation
Stay connected — spend time with others in person, online, or by phone.
12
Physical Inactivity
Aim for at least 2.5 hours of moderate activity each week, such as walking, dancing, or gardening.
13
Air Pollution
Limit exposure to poor air quality. Stay indoors on high-pollution days or use a mask outdoors if needed.
14
Sleep Problems
Adults need 7 to 9 hours of quality sleep each night. Seek help if you feel tired or have trouble sleeping.
Take Action for Your Brain
Talk to your family doctor or healthcare provider about any of these risks.
Small steps matter — improving even one area can make a real difference.
