Preventing Dementia

How to Prevent Dementia?

Research on prevention of dementia is ongoing.^[2] There are steps you can take that may be effective in preventing dementia.

• Keep your mind active. Engage in mentally stimulating activities. They may help you cope with the changes associated with dementia. Such activities include playing games, working puzzles, learning a language, playing an instrument, reading, writing and various arts.
• Be physically and socially active. These activities can delay the onset of dementia and reduce its impact. Walking, swimming and dancing are options. Social activities can include playing cards and going to the theater or museums.
• Maintain a healthy diet. A diet rich in fruits, vegetables, and omega-3 fatty acids can protect against dementia. Omega-3 fatty acids are found in certain fish and nuts.
• Reduce homocysteine levels. High doses of B vitamins (folic acid, B6 and B12) can lower homocysteine and may slow the worsening of Alzheimer's disease. Discuss this with your doctor before starting supplements.
• Lower cholesterol levels. High levels of cholesterol can affect the blood vessels in the brain and cause vascular dementia. It is important to keep your cholesterol levels low. Consult with your doctor for testing and treatment if needed.
• Control diabetes. Controlling diabetes can reduce the risk of Alzheimer's disease and vascular dementia. See your doctor for testing for diabetes.
• Lower blood pressure. Maintaining normal blood pressure reduces the risk of Alzheimer's disease and vascular dementia. A healthy diet and regular exercise can help. If these aren't enough, talk with your doctor.
• Maintain vaccinations. Staying current with vaccinations may have a protective effect against dementia. Talk with your doctor about flu, tetanus, diphtheria and polio vaccinations, which appear to reduce the risk of Alzheimer's disease.
