These are 50yos, not elderly retirees. What if knowing caused your employer to deny you a promotion? Im in the military. This sort of diagnosis on one's file could have real impact on future prospects. People already fear ADHD tests for the same reason. I know a guy who is leaving the military after 20+ years flying transports. He is applying to airlines. If you were an airline, would you higher an experienced pilot with a positive alzheimer's diagnois in thier medical data?
