Certain lifestyle changes have been shown to affect, if slow down, the progression of age-related dementia and Alzheimer's disease. Here are some of the more common recommendations, excerpted from the website of Dr. Andrew Weil.

• Follow a diet rich in antioxidants, with an emphasis on whole grains, fruits, vegetables, fish, nuts and seeds.
• Supplement with vitamins E and C.
• Institute a program of daily exercise to improve circulation and keep the brain oxygenated.
  
• Get adequate mental exercise through reading and socializing.
• Consider taking a daily low-dose aspirin, as doing so has been shown in studies to reduce the risk of Alzheimer's.
  

If age-related dementia or Alzheimer's is a concern you have for yourself or a loved one, speak with a physician about additional methods of prevention.
