Thirty-five elderly patients were investigated because of clinical signs of dementia. The presence or diffuse cerebral atrophy, and its severity, were determined by the use of computed tomography (CT scan). All of the patients were also examined by electroencephalography (EEG), and the presence of diffuse abnormalities, especially diffuse slowing, was noted. Specifically, patients with normal or near-normal EEGs were compared with those with severe diffuse slowing. No correlation between the presence or severity of diffuse EEG abnormalities and the degree of cerebral atrophy as measured by CT scan was found. Though the EEG is clearly identifying physiological dysfunction of nerve cells in demented patients it does not appear to be reliable tool for the prediction of diffuse cerebral atrophy in this population.
35名老年患者因出现痴呆临床症状而接受调查。通过计算机断层扫描（CT扫描）确定是否存在弥漫性脑萎缩及其严重程度。所有患者还接受了脑电图（EEG）检查，并记录了是否存在弥漫性异常，尤其是弥漫性减慢。具体而言，将脑电图正常或接近正常的患者与严重弥漫性减慢的患者进行了比较。未发现脑电图弥漫性异常的存在或严重程度与CT扫描测量的脑萎缩程度之间存在相关性。虽然脑电图能够明确识别痴呆患者神经细胞的生理功能障碍，但它似乎并不是预测该人群弥漫性脑萎缩的可靠工具。
