Frequency analysis and topographic mapping of EEG were studied in 20 consecutive patients with mild stroke and in 20 age-matched normal subjects. Abnormally large increases in delta and decreases in alpha activity were seen over the scalp in 17 of 20 patients and in no normal subjects. Theta was unreliable by itself. The scalp area so localized appeared correct in each case compared with signs, symptoms, and neuroimaging studies. These computerized EEG analysis techniques were abnormal significantly more often than routine EEGs. The results obtained here with simple techniques agree with past studies done with more complex types of EEG analysis.
对20例轻度中风患者和20名年龄匹配的正常受试者进行了脑电图的频率分析和地形图绘制。20例患者中有17例头皮上出现δ波异常大幅增加和α波活动减少，而正常受试者中未出现这种情况。θ波单独来看不可靠。与体征、症状和神经影像学研究相比，每种情况下如此定位的头皮区域似乎都是正确的。这些计算机化脑电图分析技术出现异常的频率明显高于常规脑电图。这里用简单技术获得的结果与过去用更复杂类型的脑电图分析所做的研究一致。
