本文分析681例正常中老年人脑血流图、脑电图结果表明,自40岁起随年龄增加血管弹性逐渐减低、紧张度逐渐增高,但老年人改变较中年人更为显著(差别有特别显著意义P<0.01),其变化提示脑动脉硬化。但脑电图之明显异常表现,表明脑衰老似慢于脑血管功能状态改变。在反映脑血管功能状态上脑血流图则比眼底检查更为灵敏。为了解中、老年人尤其老年人脑血管功能状态与脑电活动相应关系,本文就219例正常老年人与462例正常中年人脑血流图、脑电图进行初步分析：
EEG analysis of 681 normal middle-aged and elderly patients showed that the EEG decreased gradually with the increase of age from the age of 40, and the tension increased gradually. However, the change of the elderly was more significant than that of the middle-aged (the difference was Particularly significant P <0.01), the changes suggest cerebral arteriosclerosis. However, the obvious abnormalities of EEG indicate that brain aging is slower than that of cerebrovascular function. Cerebral blood flow patterns that reflect cerebrovascular function are more sensitive than funduscopic findings. In order to understand the corresponding relationship between cerebrovascular functional status and EEG activity in middle-aged and elderly people, especially in the elderly, this paper preliminary analysis of cerebral blood flow diagram and EEG in 219 normal elderly and 462 normal middle-aged:
