Prosopagnosia is a neurological disorder characterized by the inability to recognize faces. Also known as face blindness or facial agnosia, prosopagnosia can make it difficult for people to recognise faces and they may not even be able to distinguish a face as being different from an object. Some may not be able to recognize their own face.
Prosopagnosia is taken for memory dysfunction, memory loss, impaired vision, or learning disabilities. It is believed to be a result of abnormalities, damage, or impairment in the right fusiform gyrus (a fold in the brain that appears to coordinate the neural systems that control facial perception and memory). The condition may occur as a result of stroke, traumatic brain injury or certain neurodegenerative diseases.
In some cases it is a congenital disorder, present at birth in the absence of any brain damage, and is known as congenital prosopagnosia. Some degree of prosopagnosia is often present in children with autism and Asperger’s syndrome, and may be the cause of their impaired social development.
It is difficult to live with the condition as those affected have difficulty recognizing family members and close friends. They often use other ways to identify people, such as relying on voice, clothing, or unique physical attributes, but these are not as effective as recognizing a face.
Children with the condition require better communication techniques to fix the impairments and make the disorder less overlooked in the future.
