Multi-modal hemispatial deficits after left hemisphere stroke. A disorder of attention?

Brain. 1993 Jun;116 ( Pt 3):527-54. doi: 10.1093/brain/116.3.527.


We report a patient who, after suffering infarcts involving the left temporo-parietal and left anterior cingulate regions, performed significantly worse on a variety of motor, language and sensory tasks when he acted in or attended to right hemispace. Performance on a number of tasks was better when acting in near as compared with far peri-personal space and with his head deviated to the left as compared with the right. Additionally, performance with the 'unaffected' left hand was often worse in right as compared with left hemispace. We propose that his deficits are attributable to a disruption of a left hemisphere-specific attentional system which normally serves to regulate the activation and articulation of left hemisphere processing modules.
