本文报告维哈汉三民族的纯右利脑血管病病人,就他们的偏瘫与失语临床表现在民族之间并与西方资料进行比较。中国人右侧偏瘫(左侧半球损害)失语者远比西方人为少,左侧偏瘫(右半球损害)交叉性失语大大高于西方人。维哈族右侧偏瘫(左侧半球损害)失语者又远比汉族为少,故大脑功能偏侧化存在民族差异,传统的优势半球理论似应受到某些质疑。 This article reports on patients with pure right-sided cerebrovascular disease in the three ethnic groups of Wehahans, comparing their clinical manifestations of hemiplegia and aphasia with ethnicity and with Western data. Chinese right hemiplegia (left hemisphere damage) aphasia is far less than the Westerners, left hemiplegia (right hemisphere damage) cross aphasia is much higher than Westerners. The Wehra hemiplegia (left hemisphere damage) aphasia is far less than the Han nationality, so there are ethnic differences in the lateral function of the brain, the traditional dominant hemisphere theory should be subject to some questions.
