Alzheimer's disease remains among the most devastating diseases that medicine has yet to crack.There's no known cure or treatment that has substantially helped curb memory loss and the decline in cognitive skills.One in eight Americans over the age of 65 has Alzheimer's now.Researchers are hoping they can find a more promising future by intervening well before any symptoms show.Jeffrey Brown has the story.This photograph is a picture of my father and myself at a father/daughter dance at school.At age 48, Jamie Tyrone decided on a whim to sign up for a study that offered genetic testing for 22 diseases.This is at my wedding day.The results were shocking and life-changing.My genetic status is that I have a 91 percent lifetime risk of getting Alzheimer's disease.Alzheimer's, a debilitating form of dementia, wasn't even on Tyrone's radar screen. She'd had no symptoms.And hearing the news sent her into an emotional tailspin.I was very, very lonely and very, very isolated.And at one point, I was told that it's probably best not to talk about it because you might be discriminated against.And so I went into a really dark hole.All this began five years ago, ironically, just as her father began showing signs of mental confusion.
