To assess the value of EEG in distinguishing between cortical and subcortical dementia, we compared the EEGs of 22 patients with SRO syndrome with those of 22 patients who had a comparable degree of dementia due to cortical atrophy. EEG records from patients with SRO syndrome were of low voltage, but with preserved alpha rhythm at 8-10 Hz and were within normal limits in 12/22. In 8 there was an abnormal excess of theta activity and one had additional lateralizing asymmetries. One had frontal intermittent rhythmic slow wave activity. Comparison with records of 22 patients, with cortical atrophy due to Alzheimer's disease but with only mild to moderate dementia, showed a similar low frequency of non-specific abnormalities.
为评估脑电图（EEG）在区分皮质性痴呆和皮质下痴呆中的价值，我们比较了22例患有SRO综合征患者的脑电图与22例因皮质萎缩导致程度相当的痴呆患者的脑电图。SRO综合征患者的脑电图记录为低电压，但保留了8 - 10Hz的α节律，22例中有12例在正常范围内。8例存在异常增多的θ活动，1例有额外的侧化不对称。1例有额部间歇性节律性慢波活动。与22例因阿尔茨海默病导致皮质萎缩但仅有轻度至中度痴呆患者的记录相比，非特异性异常的发生率相似。
