Prosopagnosia (face blindness)

Prosopagnosia, also known as face blindness, is a neurological condition where the brain struggles to recognize faces, including familiar ones like friends or family. It is usually caused by damage or developmental issues in the fusiform gyrus, a brain area dedicated to face recognition. People with prosopagnosia may rely on other cues—such as voice, clothing, or context—to identify individuals. The condition varies in severity; some can't recognize faces at all, while others recognize most but have difficulty with certain types or unfamiliar faces. It does not affect intelligence or the ability to see, only the recognition of faces.
