Nine normal elderly subjects and 81 patients with dementia have been studied by computerised tomography (CT) and electroencephalography (EEG). There was a broad relationship between slowing of the basic frequency of the EEG and the severity of mental impairment. Localised slow-wave activity was found in 19% of those with non-vascular dementia and 72% of those with dementia of vascular origin. The mean size of the ventricles, as determined from CT scans, was larger in the vascular than in the non-vascular group. Within the vascular group it was larger in those without than in those with visible infarcts. There was no relationship in either group between ventricular size and dominant EEG frequency.
通过计算机断层扫描（CT）和脑电图（EEG）对9名正常老年人和81名痴呆患者进行了研究。脑电图基本频率减慢与精神损害的严重程度之间存在广泛的关系。在19%的非血管性痴呆患者和72%的血管性痴呆患者中发现了局限性慢波活动。根据CT扫描确定，血管性痴呆组的脑室平均大小大于非血管性痴呆组。在血管性痴呆组中，无可见梗死灶的患者脑室比有可见梗死灶的患者更大。两组中脑室大小与脑电图优势频率之间均无关系。
