How do you prevent alzheimer's disease

No known method: Or treatment has been proven to prevent alzheimer's disease.

No absolute way, but: A recent study sheds light on one of the most effective way to prevent dementia. See my blog at http://mdprevent.Blogspot.Com/2013/02/if-you-jump-up-and-down-after-reading.Html. Berries, wild salmon, and turmeric mixed with piperine, plus learning a new skill have also been suggested as helpful.

It is unknown: The only intervention with a moderate amount of evidence is exercise. General priniciples for brain health include avoiding head injuries (and sports or activities associated with them), successfully managing any chronic health problems like diabetes and high blood pressure. A generalization is that if it is good for heart health, it is probably also good for your brain.
