autotopagnosia
[ô′tōtop′əg·nō′zhə]
Etymology: Gk, autos + topos, place, a + gnosis, without knowledge
the inability to recognize or localize the various body parts because of organic brain damage. It is associated generally with lesions of the dominant hemisphere and may be an effect of some cases of cerebrovascular insult (CVI). It is also characterized by a loss of ability to distinguish left from right, manifested during a neurologic examination when the patient is unable to perform a task such as touching the right ear with the left thumb. Retraining involves touching various parts of the patient's body and asking the patient to identify the area touched and by having the patient assemble human figure puzzles. Also called body-image agnosia, body-scheme disorder. See also agnosia, proprioception.
