Unfortunately, there is no definitive, scientifically-proven way to reduce the risk of developing Alzheimer’s and other causes of dementia. Scientists are working to identify risk factors, and ways of modifying those elements. Age, genetics, and lifestyle all may play a part. There is growing evidence that a combination of interventions, i.e., aerobic exercise, weight training, optimal sleep patterns, a Mediterranean diet, reducing stress, social and cognitive engagement can help improve overall health, including the cognitive health, of older adults.
In the video below, Dr. Rudolph Tanzi of Harvard Medical School, a longtime Alzheimer's researcher, shares suggestions that can encourage brain health for Alzheimer's: Every Minute Counts, produced by Twin Cities PBS.
