Prosopagnosia

Prosopagnosia is the inability to recognise faces. There are varying degrees of impairment and only the recognition of familiar faces can be affected. There is usually preservation of other aspects of visual processing and intellectual functioning. With the most extreme impairment the sufferer cannot distinguish faces from other objects or their own faces. The ability to recognise faces is anatomically located in the fusiform gyrus and damage to this area leads to prosopagnosia.

Causes include stroke, traumatic brain injury and neurodegenerative diseases such as posterior cortical atrophy. Congenital prosopagnosia has been reported.
