EEG indicators were correlated with clinical items in 174 patients with dementia diagnoses based on the DSM-III-R criteria. The patients' clinical symptomatologies were presented as regional brain syndromes, i.e. parietal lobe, frontal lobe, subcortical and global (nonregional) syndromes. The EEGs were abnormal in 87% of the cases. The typical abnormalities consisted of diffusely distributed slow wave activity. A significant correlation was found between the degree of slow wave abnormality and the degree of dementia. The results of the statistical analysis also suggest that EEG slow wave activity in dementia primarily reflects parietal lobe dysfunction. No association seems to exist between EEG slow wave activity and frontal lobe dysfunction.
根据《精神疾病诊断与统计手册》第三版修订版（DSM-III-R）标准，对174例痴呆症患者的脑电图指标与临床项目进行了相关性分析。患者的临床症状表现为区域性脑综合征，即顶叶、额叶、皮质下和全身性（非区域性）综合征。87%的病例脑电图异常。典型异常表现为弥漫性分布的慢波活动。慢波异常程度与痴呆程度之间存在显著相关性。统计分析结果还表明，痴呆症患者的脑电图慢波活动主要反映顶叶功能障碍。脑电图慢波活动与额叶功能障碍之间似乎没有关联。
