Spatial neglect is a cluster of symptoms characterized by a failure to orient, or react to stimuli located predominantly on the contralesional side. This could be subdivided into personal, peripersonal and extrapersonal neglect in terms of spatial frame of reference. In the perceptual point of view, one can classify into further perceptual and representational neglect. In this review, subtypes of spatial neglect were conceptualized by spatial frame of reference and perception in relationship with their neuroanatomical correlates. Furthermore, its assessment was discussed according to those subtypes.
