Ever since a family member was diagnosed with Alzheimer's, I've been paying attention to reports like these. Every other year, there is a paper about a major breakthrough, and surely a cure should be just around the corner any time now.
Every few years there is a paper that claims that we now finally know what causes the disease, and every time it's something different, and every time you never hear of a followup.
It's about 3 decades later now, and as far as I can tell, there is still no actual progress in the way of treatment. An alzheimer's diagnosis still means the same as it did in the 80's or in the 60's for that matter.
About this cure that is just around the corner. It came too late for my grandparents generation, it came too late for my parents' generation, it came too late for my generation, I wouldn't be surprised if it came too late for my children's generation. I don't believe in it any more.
