What it's like not to recognize people: the phenomenon of face blindness

The article explains the phenomenon of prosopagnosia, a neurological disorder in which a person cannot recognize faces. It describes two forms: congenital and acquired. It provides data on prevalence (one in fifty people worldwide), brain mechanisms, and adaptation strategies.

The article discusses prosopagnosia, or 'face blindness,' a neurological disorder in which a person loses the ability to remember and identify faces. It describes two forms: acquired (after injuries, strokes) and congenital (genetic, manifesting from childhood). It provides data that approximately one in fifty people worldwide experiences this. It explains how the brain processes faces: the signal goes from the occipital cortex to the temporal area, where it is compared with memory, and to the prefrontal cortex. In people with prosopagnosia, neural connections between these areas are weaker. Diagnosis includes tests for recognizing celebrities. There is no medication, but people adapt: they arrive at meetings first, recognize people by their gait, voice, hairstyle, or clothing details.
