Becoming a caregiver for parents with Alzheimer’s… seeing the decline front and center… is actually one of the triggers for people to consider embryo screening for their children APOE e4 is the strongest genetic risk factor for Alzheimer’s e3/e4 (one copy) = ~3x risk e4/e4 (two copies) = ~12x risk We can see this in embryos. We can screen for it. You can prevent your child from inheriting increased risk.
