Global InformationAutotopagnosia information
Autotopagnosia from the Greek a and gnosis, meaning "without knowledge", topos meaning "place", and auto meaning "oneself", autotopagnosia virtually translates to the "lack of knowledge about one's own space," and is clinically described as such.[1]
Autotopagnosia is a form of agnosia, characterized by an inability to localize and orient different parts of the body.[2] The psychoneurological disorder has also been referred to as "body-image agnosia" or "somatotopagnosia." Somatotopagnosia has been argued to be a better suited term to describe the condition. While autotopagnosia emphasizes the deficiencies in localizing only one's own body parts and orientation, somatotopagnosia also considers the inability to orient and recognize the body parts of others or representations of the body (e.g., manikins, diagrams).[3]
Typically, the cause of autotopagnosia is a lesion found in the parietal lobe of the left hemisphere of the brain.[3] However, it as also been noted that patients with generalized brain damage present with similar symptoms of autotopagnosia.[4] As a concept, autotopagnosia has been criticized as nonspecific; some claim that this is a manifestation of a greater symptomatic complex of anomia, marked by an inability to name things in general—not just parts of the human body.[5]
