Imagine having to memorize the most predominant features of your family’s and friends’ faces so you will recognize them each time you see them. While it sounds like a medical enigma straight from the TV drama ‘House,’ prosopagnosia or ‘face blindness’—a condition believed to be caused by an impairment in a fold of the brain controlling facial perception and memory— affects about 2 percent of the population. In this fascinating interview, a woman with prosopagnosia shares how she’s walked past her husband and children multiple times without recognizing them and how she familiarizes people by observing their body language or listening to their voices. While there isn’t a set treatment for it, building awareness and support networks is key since those with prosopagnosia often struggle with social anxiety and phobias. If this applies to you or someone you know feel free to share any personal experiences in the comments.
