A 39-year old patient abruptly presented with global aphasia. Six years later a mild deficit of articulation and sentence comprehension persisted. A cerebral blood flow study showed that a) during verbal activations, the blood flow increased in the right hemisphere and decreased around the lesion in the left hemisphere; b) the activation was globally higher than in the control group. These data suggest that the right hemisphere plays a significant role in the recovery from aphasia in patients with severe left hemispheric lesions.
一名39岁患者突然出现完全性失语。六年后，仍存在轻度的发音和句子理解缺陷。一项脑血流研究显示：a）在言语激活期间，右半球血流增加，左半球病灶周围血流减少；b）激活程度总体上高于对照组。这些数据表明，右半球在严重左半球病变患者的失语恢复中起重要作用。
