There's no sure way to prevent dementia, but there are steps you can take that might help. More research is needed, but it may be beneficial to do the following:

  • Keep your mind active. Mentally stimulating activities, such as puzzles and word games, and memory training may delay the onset of dementia and help decrease its effects.
  • Be physically and socially active. Physical activity and social interaction may delay the onset of dementia and reduce its symptoms.
  • Quit smoking. Some studies have shown smoking in middle age and older may increase your risk of dementia and blood vessel (vascular) conditions. Quitting smoking may reduce your risk.
  • Lower your blood pressure. High blood pressure may lead to a higher risk of some types of dementia. More research is needed to determine whether treating high blood pressure may reduce the risk of dementia.
  • Pursue education. People who have spent more time in formal education appear to have a lower incidence of mental decline, even when they have brain abnormalities. Researchers believe that education may help your brain develop a strong nerve cell network that compensates for nerve cell damage caused by Alzheimer's disease.
  • Maintain a healthy diet. Eating a healthy diet is important for many reasons, but a diet rich in fruits, vegetables and omega-3 fatty acids, commonly found in certain fish and nuts, may promote overall health and lower your risk of developing dementia.
