Fifty-six patients with senile dementia of Alzheimer type and 84 normal elderly people were examined by EEG and computed tomography. In discriminant function analysis of the computed tomography indexes the highest discriminant function coefficient was for width of the third ventricle. Using computed tomography, the groups were correctly classified for 84% of the subjects. In discriminant function analysis of the EEG variables the highest discriminant function coefficient was for dominant occipital rhythm; the groups were correctly classified for 86% of the subjects. In discriminant function analysis of the width of the third ventricle, an index of cortical atrophy, the dominant occipital rhythm, age and sex, the width of the third ventricle had the highest discriminant function coefficient; the groups were correctly classified for 90% of the subjects.
对56例阿尔茨海默型老年痴呆患者和84名正常老年人进行了脑电图（EEG）和计算机断层扫描（CT）检查。在CT指标的判别函数分析中，判别函数系数最高的是第三脑室宽度。使用CT，84%的受试者被正确分组。在EEG变量的判别函数分析中，判别函数系数最高的是枕叶优势节律；86%的受试者被正确分组。在对作为皮质萎缩指标的第三脑室宽度、枕叶优势节律、年龄和性别的判别函数分析中，第三脑室宽度的判别函数系数最高；90%的受试者被正确分组。
