Question: What Is Prosopagnosia?
Answer: Prosopagnosia is the inability to recognize the identity of familiar faces. People with prosopagnosia can tell you that a face is a face, and they can even identify each part of the face (e.g, nose, mouth, etc). However, they can’t tell you whose face they are looking at.
Prosopagnosia often results from a stroke in a very specific area at the border between the occipital and the temporal lobes of the brain.
