Developmental prosopagnosia is a lifelong condition that impairs a person’s ability to recognize faces, in the absence of sensory visual problems and intellectual impairment. People with this condition have normal intelligence and memory, typical low-level vision, and no history of brain injury. They typically learn to use non-face cues including voice, walking style (gait) and hairstyle to recognize others. Symptoms that may vary include whether a person can perceive facial expressions normally, or recognize objects normally. The underlying genetic cause of developmental prosopagnosia is not yet known. Familial reports of this condition are consistent with autosomal dominant inheritance.
Developmental prosopagnosia differs from acquired prosopagnosia, in which a person develops face recognition difficulties as a result of brain injury (for example, from a stroke or trauma).
