A group of 53 patients rendered acutely aphasic by occlusive cerebrovascular disease were studied by serial EEG's, repeated neurologic examinations and speech evaluations (Porch Index of Communicative Ability) over a period of eight to twenty-four months, in order to correlate EEG findings with the degree of language disorder and prognosis for language recovery. Normal and mildly abnormal EEG's, posterior slow foci, focal slowing of semirhythmic type and higher alpha frequencies over the intact hemisphere correlated with good language recovery. In the majority of the patients, the curves of "EEG Improvement" and "Language Recovery" closely paralleled each other. These data indicate that the EEG is of prognostic value as to recovery from aphasia in patients suffering from acute occlusive cerebrovascular disease. Despite the advent of newer diagnostic tests, such as CAT scan, which has established its value in evaluation of the anatomy of aphasia, (9) EEG remains to be useful as a tool that could predict the outcome of aphasia in stroke patients.
一组因闭塞性脑血管疾病而急性失语的53名患者，在8至24个月的时间里，通过系列脑电图、反复的神经学检查和言语评估（交际能力的波奇指数）进行了研究，以便将脑电图结果与语言障碍程度及语言恢复预后相关联。正常和轻度异常脑电图、后部慢波灶、半节律型局灶性慢波以及健侧半球较高的α频率与良好的语言恢复相关。在大多数患者中，“脑电图改善”曲线和“语言恢复”曲线密切平行。这些数据表明，脑电图对于急性闭塞性脑血管疾病患者失语症的恢复具有预后价值。尽管出现了更新的诊断测试，如计算机断层扫描（CAT扫描），其在失语症解剖学评估中的价值已得到确立，但脑电图作为一种能够预测中风患者失语症预后的工具仍然有用。
