Core Tip

Core Tip: Prosopagnosia is a rare condition characterized by the loss of familiarity with previously known faces and the inability to recognize new faces. We present a case of delayed diagnosis of prosopagnosia after a right hemisphere stroke in an elderly man who only presented with progressive "blurred vision" without any facial recognition impairment. Further functional magnetic resonance imaging revealed that the visual recognition deficits were face-specific. This case report demonstrates that the presentation of prosopagnosia can be atypical, and visual difficulties could be a clinical manifestation solely of prosopagnosia. This case highlights the importance of routinely considering prosopagnosia as a potential impairment after stroke.
