About half the nuns developed Alzheimer's disease or other forms of dementia before they died, about similar to the general population.

Half of the original 677? That's surprising. There must be something in their environment that is causing it. I find it hard to believe that half of the general population develops Alzheimer's disease.

That does seem a little bit high.
