Memory Loss and Dementia - Prevention

Can dementia be prevented?

At present, there are no specific medicines or treatments that are definitely known to reduce your chance of developing dementia. However, some things do show some promise.

As mentioned above, having risk factors for cardiovascular disease can increase your risk of developing all types of dementia. These risk factors include:

  • Smoking.
  • Raised cholesterol levels.
  • Drinking too much alcohol.
  • Not doing enough physical activity.
  • Being overweight.
  • Having diabetes or high blood pressure.

Therefore, it would seem likely that doing something to modify these risk factors may reduce your risk of developing dementia. Stopping smoking, reducing excessive alcohol, and losing weight if you are overweight, for example, may all help to reduce your risk of dementia. Regular physical exercise is advised for all sorts of health benefits, including reducing the risk of dementia. One UK study suggested that a fifth of cases of Alzheimer's disease might have been related to lack of physical activity, and proposed that regular exercise might have actually prevented some of these cases.

Keeping your brain active may also help to reduce your risk of developing dementia. So, for example, consider reading books, doing puzzles, learning a foreign language, playing a musical instrument, taking up a new hobby, etc.

Many studies are going on to look into treatments which may help to prevent dementia. These include certain blood pressure medicines, omega-3 fatty acids, and brain training exercises, as well as the strategies discussed above. However, there is not yet convincing evidence available for any of these.

Further research is ongoing to try to find other ways of preventing dementia.
