Face blindness, medically known as prosopagnosia, is a neurological condition characterized by the inability to recognize familiar faces, including those of acquaintances, friends, family members, and even one's own face. It is not related to vision problems, memory loss, or learning disabilities, but results from abnormalities, damage, or impairment in the brain area called the right fusiform gyrus, which is responsible for facial perception and memory. The condition can be congenital (present from birth) or acquired later in life due to brain injury, stroke, or neurodegenerative diseases. People with prosopagnosia may still see faces clearly but cannot identify who the faces belong to. This can create significant social challenges, making it difficult to recognize close family, friends, or colleagues and sometimes leading individuals to rely on alternative cues like voice, clothing, or distinctive physical features. Prosopagnosia varies in severity; some may struggle only with unfamiliar faces, while others cannot recognize even well-known faces or their own. It affects about 2% to 3% of the population, with some studies suggesting it might be more common than previously thought. There is currently no cure for prosopagnosia, but people with the condition can learn compensatory strategies to help recognize others in different ways. Awareness and understanding of face blindness are growing, helping those affected manage the social impacts of the disorder. In summary, face blindness is a brain- based disorder that impairs facial recognition despite normal vision and other cognitive functions, impacting social interactions profoundly.
