Would you want to know the date and time of your death? Life-Line, the first published fiction by Robert A. Heinlein, one of the giants of 20th century science fiction, explored that question. The story’s protagonist, Hugo Pinero, had invented a machine that could tell precisely when individuals would die, but, as Pinero found to his distress, he could not intervene to change their fates.
Would you want to know whether you would be diagnosed with Alzheimer disease (AD)? This question is rapidly leaving the realm of science fiction; indeed, it already has for some unlucky people. Our ability to predict who will suffer from this evil (and I chose that word carefully) condition is proceeding on several fronts and may already be coming into clinical use.
This post will briefly note the ways in which AD prediction is advancing and what some of the ethical, legal, and social implications of such an ability would be, before asking “should we care?”

Several different techniques are providing information about an individual’s risk of being diagnosed with AD, including genetics, biomarkers, and neuroimaging.
Genetics can predict AD with great confidence for about one person in a thousand.
