Prosopagnosia is a neurological disorder in which a person is unable to recognize faces. Prosopagnosia is also known as face blindness or facial agnosia. prosopagnosia in Greek means “face” and “lack of knowledge.
In prosopagnosia, some people may only experience difficulty in recognizing a familiar face while others may be unable to discriminate between the unknown faces. However, the situation may even worse for some as they may not even distinguish a face as being different from an object and some are not able to recognize their own face. The condition is thought to be result of damage or impairment in the right fusiform gyrus but is not related to memory dysfunction, memory loss, impaired vision or learning disabilities.
A stroke, traumatic brain injury or certain neurodegenerative diseases can lead to prosopagnosia. Some people may have congenital prosopagnosia which tends to run in families making a genetic mutation or deletion. Children with autism and Asperger’s syndrome may have some degree of prosopagnosia leading to impaired social development.
The treatment is done to help the individual develop compensatory strategies. People in which stroke or brain trauma leads to prospagnosia are retrained to use to clues to identify the faces.
