Yeah, and I'm not sure that a drug that reverses the symptoms is a realistic target anyway. As far as I'm aware, Alzheimer's ultimately kills neurons. They ain't coming back without a time machine. A treatment that stops degeneration is as good a goal as we're gonna get.

Like, if I lose a limb in a car accident, is it really fair to say that the intervention required to let me live on as an amputee didn't work, since it couldn't grow my limb back?
