Preliminary, observational evidence suggests that risk of Alzheimer disease may be decreased by the following:
- Continuing to do challenging mental activities (eg, learning new skills, doing crossword puzzles) well into old age
- Controlling hypertension
- Lowering cholesterol levels
- Consuming a diet rich in omega-- fatty acids and low in saturated fats
- Drinking alcohol in modest amounts
However, there is no convincing evidence that people who do not drink alcohol should start drinking to prevent Alzheimer disease.
