Short answer · Medically reviewed summary · Last updated: 2026-05-08
Prosopagnosia, commonly referred to as "face blindness," is a neurological condition characterized by the inability to recognize familiar faces, including those of close friends and family members. While Prosopagnosia is the standardized medical term, it is frequently categorized into two distinct types: developmental (congenital) Prosopagnosia and acquired Prosopagnosia, which results from brain injury or neurodegenerative disease. What are the common synonyms and terminology for Prosopagnosia? In medical literature and clinical documentation, Prosopagnosia is the most widely accepted term, derived from the Greek words prosopon (face) and agnosia (not knowing).

Prosopagnosia, commonly referred to as "face blindness," is a neurological condition characterized by the inability to recognize familiar faces, including those of close friends and family members. While Prosopagnosia is the standardized medical term, it is frequently categorized into two distinct types: developmental (congenital) Prosopagnosia and acquired Prosopagnosia, which results from brain injury or neurodegenerative disease.
What are the common synonyms and terminology for Prosopagnosia?
In medical literature and clinical documentation, Prosopagnosia is the most widely accepted term, derived from the Greek words prosopon (face) and agnosia (not knowing). Patients may encounter several alternative names depending on the context of their diagnosis:
- Face blindness: The most common colloquial term used by patients and in media.
- Facial agnosia: A less common, older clinical synonym.
- Perceptual prosopagnosia: Sometimes used to describe deficits in visual face processing.
- Apperceptive prosopagnosia: A historical term used in older neurology texts to describe a failure in the initial visual perception of faces.
Why are there multiple names for this condition?
The existence of multiple names for Prosopagnosia stems from the evolution of neurological understanding. Historically, the condition was described as an "agnosia," a broader category of sensory perception failures. Over time, as researchers distinguished between congenital cases (present from birth) and acquired cases (post-stroke or trauma), the terminology became more nuanced. Today, medical professionals prefer the term Prosopagnosia as it most accurately reflects the specific deficit in facial identity processing rather than general visual impairment.
How is the condition classified in medical systems?
Official classification helps ensure consistency in medical records. Prosopagnosia is recognized under the following identifiers:
- Orphanet: Listed as ORPHA:75467.
- ICD-11: Categorized under "Disorders of visual perception" (MB21.1).
- OMIM: Often referenced in the context of developmental face recognition deficits (MIM #607370).
