Does Contralateral Neglect Occur More Often in RBD Than LBD?
This review supported the belief that contralateral neglect occurs more often after RBD than LBD. The frequency of contralesional (left-sided) USN after RBD ranged from 12% to 100% in the 30 studies that prospectively recruited RBD stroke patients. The frequency of contralesional neglect after LBD in the 17 studies that recruited LBD stroke patients ranged from 0% to 76%. To answer the question of whether contralateral neglect occurs more often in RBD than LBD, only those 17 studies that compared both were considered. [2,5,29-43] This information is summarized in Table 3. Comparison of these studies’ findings suggests that there is a higher occurrence of neglect in the RBD subjects. In all but 1 of the 17 studies reviewed, the occurrence rate is higher after RBD than LBD. The exception is 1 study [5] that reported almost equivalent rates for both groups of 75 RBD and 75 LBD subjects 1 month after stroke.
