目的:观察慢性脑供血不足患者认知功能,并寻找早期识别认知功能下降的方法。方法:对所有入组者进行认知功能量表及脑电图检查,将病例组结果与对照组进行统计学分析,比较差异性。结果:慢性脑供血不足患者在认知功能方面较正常老年人下降,但未达到痴呆标准。在脑电图上表现为轻度或中度异常。结论:脑电图可能是早期识别认知功能下降的有效方法。
OBJECTIVE: To observe the cognitive function of patients with chronic cerebral insufficiency and to find out the method of early recognition of cognitive decline. Methods: All participants were enrolled in the cognitive function scale and electroencephalogram examination. The results of the case group and the control group were statistically analyzed to compare the differences. Results: Patients with chronic cerebral insufficiency decreased cognitive function more than the normal elderly, but did not meet the criteria of dementia. In the EEG showed mild or moderate abnormalities. Conclusion: EEG may be an effective method to identify the decline of cognitive function in the early stage.
