For generations, Alzheimer's disease has arrived as a verdict delivered too late — confirmed only after memory had already begun its retreat. This week, the FDA approved the first blood test capable of detecting the disease's molecular signatures years before symptoms emerge, developed through a collaboration between Roche and Eli Lilly. The approval marks a turning point not merely in diagnostics, but in the deeper human relationship with time, foreknowledge, and the possibility of intervention — shifting Alzheimer's from a condition discovered in its aftermath to one that might, at last, be
