Disorders of visuo-spatial attention in patients with unilateral brain damage.
Visuo-spatial inattention (VSI) was examined in 390 patients with ischemic insult to the right or left cerebral hemispheres. VSI was revealed in 44 out of 80 patients with right parietal lobe damage and in 30 out of 70 subjects with right occipital lobe injury. Only one patient out of 100 with left hemisphere injury has shown the signs of VSI. These data confirm the suggestion that the right parietal and occipital regions are crucial for visuo-spatial attention, whereas the left hemisphere is of minor import.
