SPATIAL FRAMES OF VISUAL HEMINEGLECT IN PATIENT WITH HIGH-GRADE GLIOMA , A CASE REPORT AND REVIEW OF LITERATURE

ABSTRACT Visual hemispatial neglect is a behaviour deficit due to brain damage affecting mostly temporoparietal junction region of the right hemisphere. There is a controversial finding of various studies regarding the spatial reference of the disorder. Some study reported that space-centred neglect (egocentric) neglect and object-centred (allocentric) neglect are two dissociable disorder. In contrast, others reported that the two types of neglects are the spectrum of a disorder that share the same basic mechanism. The case presented here is a man with suspected high-grade glioma affecting the perisylvian region to the angular gyrus. Both egocentric and allocentric neglect features are revealed through the neurobehavior test performed to the patient.
