Prosopagnosia is the inability to recognize or distinguish faces. It occurs more frequently in people with aphantasia and can be congenital or acquired through brain damage.
Prosopagnosia, also called face blindness, refers to the difficulty or inability to recognize and distinguish faces, although vision itself is intact. Affected individuals often recognize known persons by voice, gait, or clothing, not by face. The developmental form affects about 2% of the population. Studies show an above-average overlap with aphantasia: many people with aphantasia also have difficulty imagining or recognizing faces. The fusiform face area (FFA) in the temporal lobe is central to face recognition. In prosopagnosia, this area is often underactive or incorrectly connected. The combination of aphantasia and prosopagnosia can make social situations difficult, as faces can neither be well remembered nor imagined.
Aphantasia is the inability to voluntarily create mental images. People with aphantasia cannot visualize faces, places, or objects in their mind's eye, although they can recognize and describe them. The term was coined by neurologist Adam Zeman in 2015.

Learn moreMental images are internal visual representations that arise without external stimuli. They enable seeing objects, scenes, or people before the "mind's eye," such as when remembering, dreaming, or planning.
