摘要/Abstract

摘要： 本研究通过对100例正常人和52例原发性癫痫病人的自发和诱发脑电功率谱的分析,证明θ高功率指标可以提高临床癫痫病人诊断的阳性率。并能客观地反映癫痫病人大脑的机能状态。对52例癫痫病人常规目测分析的阳性率为32%,而θ高功率可达56%,同时还可按谱值的高度对异常的程度进行分级。此指标可以用做临床的辅助诊断。

Abstract: Based on the analysis of power spectrum of EEG in 100 normal sub-jects and 52 patients with idiopa-thic epilepcy the present study pro-ved that by using high power spec-truln indexes the positive diagno-sis rate could be raised and the functional states of the brain in epileptics be demonstrated objecti-vely.On 52 epileptics the positive diagnostic rate was 32% by conven-tional visual analysis,whereas it was raised to 56% by using high power spectrum indexes.The extent of the brain damage could be gra-ded according to the bights of spe-ctrum valncs.So this index may be useful in assisting the clinical diagnosis.
