Autotopagnosia

Autotopagnosia is a condition which causes an individual to be unable to identify, locate, or orient their own body parts.

This condition is a type of agnosia that occurs as a result of brain damage, often time a parietal lobe lesion or cerebrovascular damage. Sufferers of this condition are also unable to distinguish their left from their right. Although the full spectrum of underlying causes is let to be fully understood it is believed that the brain damage disrupts the mental schematic representation of the body which causes difficulty in identification, location, and orientation of body parts.
