Dr. Karl Kruszelnicki has worked at the same company for years, but every day, he brings a map to the office. Why? He can’t recognize anyone.
Dr. Kruszelnicki suffers from prosopagnosia, or “face blindness,” which is a disorder that’s estimated to affect roughly 2.5 percent of the world’s population. While some people are born with it, others develop the condition as a result of a traumatic brain injury, neurodegenerative disease, or stroke. As of now, doctors have no way to treat it.
People with face blindness say that many faces appear to be upside down. With features out of place, it’s nearly impossible to recognize someone, even when they are a close friend or family member.
