A literature review by Rastogi et al suggested that malignant MCA strokes occur more frequently in the right hemisphere and that such right-sided strokes are associated with a higher morbidity rate than are those in the left hemisphere. Of 2673 patients with malignant MCA stroke for whom laterality information was available, 1687 of them (63%) had a right-hemispheric stroke, and while mortality rates between left- and right-hemispheric strokes were similar, the rate of sequelae was significantly greater for strokes in the right hemisphere.
