About This Video

Is prosopagnosia, commonly called face blindness, a communicable disease? Can you get it from a genetic mutation or just from environmental considerations? Is it a consequence of the natural process of aging—or of the progression of Alzheimer’s? Neurologist Oliver Sacks, who himself is face blind, explains the causes of the curious disorder and why you will probably not wake up with it tomorrow morning.
