Description
<p>Conscious hemiasomatognosia is a disorder of the bodily self, involving subjective symptom where patients feel as if their whole body or part of one side has disappeared. Somatosensory disturbance is considered an essential component of conscious hemiasomatognosia. We herein report a 64-year-old man with conscious hemiasomatognosia of the right arm that developed after a left parietotemporal infarction, without any somatosensory disturbance except for a unique tactile localization problem. His response to the tactile localization test suggested impaired recognition of the positional relationship of his right arm relative to the entire body but normal recognition of positional relationships within the arm. </p>
