Asymbolia dolorosa is a rare neurological disorder that causes loss of the ability to recognize people's faces and names. This is a condition that usually appears in infants and young children.
Asymbolia dilorosa can be caused by genetic or environmental factors. However, at the moment, there is no single explanation for the causes of this disorder.
For most people, asymbolia is a rather amusing abnormal disorder, since children with this disorder develop faster than normal. As children, they easily remember the faces of their parents and loved ones, but forget them when they grow up.
