AUTOTOPAGNOSIA (from Greek autos - self, own, topos - place, negative particle a-, and gnosis - knowledge), a disorder of orientation regarding one's own body or its parts. Autotopagnosia represents a special case of agnosia (see), the basis of which lies in the loss of knowledge of the "schema of one's own body."
