I am new here. I learned I had the APOE4 genes several years ago through 23 and Me. My younger sister (age 72) has been in an Alzheimer's care home for two years. I do not show any signs of the disease at 75, and hope that status continues. I live in the US, in upstate NY.

You don't say how old your children are. I have a son who is 40. I share all my health info with him so he can anticipate what might happen with my health (and with his). Young children should not be told until they are old enough, in your view, to understand and absorb the information.
