摘要
目的探讨脑卒中急性期患者安静闭眼状态下脑电非线性动力学特性的变化规律。方法用关联维数(D2)、近似熵(ApEn)对31例脑梗死患者和22名正常人在安静闭眼状态下的脑电数据进行了分析。结果脑梗死组未受损伤的双侧前额叶(FP1、FP2)D2和ApEn明显低于正常对照组。结论以D2和ApEn地形图为基础的动态分析,有助于观察脑卒中后脑功能的变化情况;脑电非线性动力学分析方法适用于脑卒中急性期脑功能变化规律的研究。
Objective To investigate the changes of non-linear dynamics characteristic of EEG in patient with acute cerebral stroke under eyes closed state. Methods EEG were recorded in 31 patients with acute cerebral infarction and 22 healthy volunteers under eyes closed state. Correlation dimension （D2） and Approximate Entropy （ApEn） were calculated for all subjects. Results D2 and ApEn of uninjured forehead cortex （FP1, FP2） reduced significantly in the group of cerebral infarction as compared with the group of normal control at eyes closed state. Conclusion Dynamic analysis based on D2 and ApEn topographic maps might be helpful in understand the changes of mental functions after stroke, that can be used in the study of mental function.
