There’s no certain way to prevent all types of dementia, as researchers are still investigating how the condition develops. However, there’s good evidence that a healthy lifestyle can help reduce your risk of developing dementia when you’re older. A healthy lifestyle can also help prevent cardiovascular diseases, such as stroke and heart attacks, which are themselves risk factors for Alzheimer’s disease and vascular dementia (the 2 most common types of dementia).
Keeping blood vessels clear of cholesterol buildup, maintaining normal blood pressure, maintaining healthy blood sugar levels, staying at a healthy weight — basically, staying as healthy as you can — can keep your brain fueled with the oxygen and nutrients it needs to function at its highest possible level. Specific healthful steps you can take include:
- Stop smoking.
- Avoid or reduce your alcohol consumption
- Follow a Mediterranean diet, which is one filled with whole grains, vegetables, fruits, fish and shellfish, nuts, beans, olive oil and only limited amounts of red meats.
- Exercise. Get at least 30 minutes of exercise most days of the week.
- Keep your brain engaged. Solve puzzles, play word games and try other mentally stimulating activities. These activities may delay the start of dementia.
- Get more physical activity.
- Stay socially active. Interact with people, discuss current events, and keep your mind, heart and soul engaged.
- Treat hearing problems
- Take care of your mental and physical health.
- Sleep well
- Prevent head injury
