They may go their whole lives struggling to recognize the important people in their lives, often relying on non-facial information like hair color or gait to distinguish people. Neuropsychologist Ashok Jansari joins Dr. Sanjay Gupta to talk about how people with prosopagnosia see the world, the mechanism behind this condition, and what can we learn from those with these deficits about face recognition.
