Agnosia is a disturbance in the perception of familiar sensory (e.g., verbal, tactile, visual) information. Unilateral neglect is a form of agnosia characterized by an unawareness or denial of the affected half of the body. This denial may range from inattention to refusing to acknowledge a paralysis by neglecting the involved side of the body or by denying ownership of the side, attributing the paralyzed arm or leg to someone else. The neglect also may extend to extrapersonal space. This defect most often results from right hemispheric brain damage that causes left hemiplegia.
