癫痫病人自发和诱发脑电图θ频段功率谱的特征
Characteristics of Power Spectrum of Spontaneous and Evoked Electroencephalographical Theta Band in the Epileptics
【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.
