本研究探讨了更大的功能不对称的男性与女性相比，对侧空间忽略的假设。138例连续的经计算机断层扫描证实的单侧首次卒中患者在发病后两个月内接受了检查。忽视的综合措施是基于四个临床任务：复制/绘图，线平分，线取消，和数字取消。忽视的发生率和严重程度显着大于右半球后比左半球的病变和平等的男性和女性。在左半球或右半球中风后，前组和后组之间没有发现性别差异。当忽视是基于不同的分数同侧与contralesional响应时间的视觉搜索任务，发病率高于男性与右半球病变的女性。
This study examined the hypothesis of greater functional asymmetry in the male compared with the female brain for contralesional spatial neglect. One hundred thirty-eight consecutive patients with computed tomography verified unilateral first strokes were examined within two months of onset. An aggregate measure of neglect was based on four clinical tasks: copying/drawing, line bisection, line cancellation, and figure cancellation. The incidence and severity of neglect were significantly greater after right-than left-hemisphere lesions and equal in men and women. Sex differences were not found between anterior and posterior groups after left- or right-hemisphere strokes. When neglect was based on different scores between ipsilateral versus contralesional response times on a Visual Search Task, the incidence was higher in females than males with right-hemisphere lesions.
