To observe the changes of EEG mapping and CT scan and analyse the correlation between the changes of the function presented by EEG mapping and morphology presented by CT.
The absolute power of EEG mapping and 9 parameters of CT in 30 normal controls and 31 patients with senile dementia were measured. The correlation was analysed quantitatively with multiple stepwise regression method.
The EEG mapping of senile dementia revealed a diffuse increase in delta, theta power and decreased alpha power in most areas. CT scan showed cortical and subcortical atrophy in brain. There were positive correlations between the increase of delta power and lateral fissure, and between the increase of delta power and average cerebral sulcus. There was a negative correlation between the decrease of alpha power and the increase of lateral fissure.
The EEG mapping and CT in patients with senile dementia are different from those in normal elderly. There is a correlation between the changes of EEG mapping and CT scan.
观察脑电地形图及CT扫描的变化，分析脑电地形图所呈现的功能变化与CT所呈现的形态学变化之间的相关性。
测量30例正常对照者和31例老年痴呆患者的脑电地形图绝对功率及CT的9项参数。采用多元逐步回归法进行定量相关分析。
老年痴呆患者的脑电地形图显示多数区域δ、θ功率弥漫性增加，α功率降低。CT扫描显示脑皮质和皮质下萎缩。δ功率增加与外侧裂增宽之间以及δ功率增加与平均脑沟增宽之间存在正相关。α功率降低与外侧裂增宽之间存在负相关。
老年痴呆患者的脑电地形图和CT与正常老年人不同。脑电地形图变化与CT扫描之间存在相关性。
