Some doctors feel it's unlikely that editing people's genes will help prevent them from getting Alzheimer's disease. It's not just because attempts to edit genes inside the cells of living animals are in their infancy. It's also because most cases of Alzheimer's disease occur in older adults, and those cases do not appear to be caused just by a few defective genes. Lifestyle—particularly exercise, diet, and the amount of high-quality sleep—affects the risk of developing Alzheimer's at least as much as genes.

Still, they should have their glucose levels checked, as prediabetes can put them at high risk for heart attack and stroke.
