I think the key issue today in dealing with the epidemic of Alzheimer’s disease is what can be done to prevent this disease, a disease for which there is no cure.

So the answer as to whether the disease can be prevented or not is clearly a strong and resounding “yes.”
Just take a look at this recent study in NEJ. We just have to broaden our educational pursuits as part of a public health effort to let people know that carbs are basically toxic to the brain.
