Some people are great at remembering faces. Once they meet you, they never forget how you look. They might say things like, "I never forget a face," or "I'm really good with faces." For some people, remembering a face can be difficult. You may have to meet them several times before they can recognize you. For others, remembering a face is simply impossible. Such people have a condition of the brain called “face blindness.” Its actual name is developmental prosopagnosia, or DP for short. Experts say DP can differ greatly from patient to patient. In less severe cases, people are unable to describe the face of someone they have just met. In severe cases, people cannot even recognize their own children in a group photograph. Many people who have DP show no clear signs.
