Cognitive decline is when your brain doesn’t work as well as it used to. For example, a person who is experiencing cognitive decline may have trouble learning, using language, or remembering things.
Some cognitive decline is a normal part of growing older. Cognitive decline that happens quickly or that affects day-to-day activities is called dementia. A head injury, a stroke, or disease (for example, Alzheimer's disease) can damage brain cells and lead to dementia.
As your body gets older, so does your brain. You can’t stop normal cognitive decline, just as you can’t stop other parts of normal aging. However, you can maintain your body and brain health by making healthy choices about your lifestyle, diet, and exercise. Healthy choices can also help prevent disease.
Although there isn't one specific diet that is best for brain health, eating a healthy diet is important for your overall health. Choosing foods that nourish your body and brain can help prevent or delay health problems, including conditions that increase your risks for dementia.
Foods that are high in saturated fats (for example, red meat) can contribute to high cholesterol levels. Over time, high cholesterol can increase your risk for heart attack and stroke. When you eat red meat, reduce your portion size. Choose poultry and fish more often.
You can also avoid unhealthy fats by using olive oil or canola oil when you are sautéing foods. Bake, broil, or roast your foods intead of frying it.
You can stay active physically, socially, and mentally. Physical activity helps prevent disease and maintain blood flow to the brain. If you don’t already exercise, try to work up to 30 minutes of moderate activity 5 times a week. Moderate activities include anything that gets your heart rate up. Walking, hiking, bicycling, and swimming are all good options. Choose something you enjoy doing like.
Any activity you do with other people helps to stimulate your brain. A social activity can be as simple as having lunch with a friend or walking around the block with a neighbor. Volunteer opportunities in your community or church are good ways to be social. Another option is finding a club or social group that focuses on a sport, hobby, or topic you enjoy.
To keep your brain cells strong and active, it’s important to stay mentally active. Challenge yourself to learn something new. Read to stay informed and for fun. Enroll in a class at a local community college or adult education center. Or, challenge yourself in a different way by playing games, completing puzzles, or trying memory exercises.
