124例原发性高血压病患者TCD与EEG对比分析

目的探讨原发性高血压病患者的经颅多普勒(T C D)及脑电图(EEG)特点。方法对124例原发性高血压病患者进行T C D及EEG检测,根据TC D和EEG的异常改变进行对比分析。结果TC D异常120例(96.7%),EEG异常28例(22.6%),且无特异性,但二者结合起来分析,对了解病变的严重程度有一定的价值。结论高血压病患者的T C D检测有较高的异常率。TC D检测有严重脑动脉硬化、脑血管重度痉挛或狭窄、脑供血明显不足的则EEG也表现为异常。因此,高血压病患者通过早期T C D和EEG检测,对临床的诊治和估计预后有一定的参考意义。

新生儿高胆红素血症的脑电图分析

目的:观察新生儿高胆红素血症对脑电图的影响和机制。方法:对60例高胆红素血症新生儿进行脑电图检测。结果:高胆红素血症新生儿EEG异常35例,异常率为58.3%,主要表现为变异性缺乏12例、低电压18例、暴发抑制4例、癫痫样放电1例。结论:高胆红素血症可引起脑电图异常,高胆红素血症轻重程度与脑电图改变有关系。

慢性酒精中毒患者的临床与电生理研究

目的:观察电生理检测对慢性酒精中毒的诊断价值。方法:对36例慢性酒精中毒患者的临床特征进行了分析,并作脑电图(EEG)、脑干诱发电位(BAEP)、神经电图(NCV)及肌电图(EMG)的检测和分析。结果:36例慢性酒精中毒患者的EEG异常27例(75%),EEG改变以弥漫性慢波增多为主。患者的EEG异常程度与饮酒量、饮酒年限呈正比关系。BAEP异常26例(72.2%),EMG检查综合判断提示神经源性损害。MCV异常率为63.9%,SCV异常率为83.3%。结论:应用电生理检测能全面反映慢性酒精中毒引起的中枢和周围神经系统的弥漫性损害,为临床提供客观指标。

慢性酒精中毒病人的临床与脑电图分析

目的:探讨酒精中毒病人的脑电图(EEG)改变与临床的关系。方法:对52例慢性酒精中毒病人的EEG检查结果进行分析。结果:43例病人的EEG异常,异常率82.7％。轻度异常占46％,中度异常35.6％,重度异常18.5％。并对35例慢性酒精中毒病人治疗2-4个月后进行EEG复查,EEG正常和明显好转者占75％。结论:EEG检查对慢性酒精中毒病人的诊断和评估疗效有一定的价值。

儿童期偏头痛与癫痫的关系

Objective. -Many studies have supported the hypothesis of alteration of cortical hyperexcitability as a possible pathological mechanism underlying the onset of migraine and epileptic attacks. Different biochemical pathways involving cellular structures may increase or decrease the excitability of neuronal membranes. The aim of this study was to identify a possible link between migraine and epilepsy from a clinical and neurophysiologic point of view. Methods. -One-hundred thirty-seven children and adolescents consecutively diagnosed for tensiontype headache and idiopathic migraine with and without aura were studied. Anamnestic, clinical, and instrumental data were collected by a neurological examination, a specific questionnaire, and awake electroencephalogram (EEG) registrations. EEG features of nonheadache and nonseizures control group were compared. Results. -Fourteen cases (10.2%) had a positive history for seizures with fever, isolated seizures, or epilepsy. Distribution differed according to headache diagnosis; migraine with aura (MWA) was largely prevalent. Specific electroencephalographic abnormalities were present in 11.7%of the sample, with a significant different distribution across the groups of children with headache and the control group: specific interictal abnormalities were found in 10 of 23 (43.5%) children with MWA. Two factors, seizures and specific interictal electroencephalographic abnormalities, showed a different distribution in patients with MWA compared to other classes of headache and control group (P≤.01). Conclusion. -The present study supports the hypothesis of a possible clinical continuum between some types of MWA and epileptic syndromes as entities due to altered neuronal excitability with similar genetic substrates.

动脉硬化性脑梗塞EEG变化与临床复发趋势的研究

目的:对194例首发、复发脑梗塞患者EEG变化研究,寻找脑梗塞患者临床复发的趋势特征。方法:就首发患者和复发患者EEG异常构成比及异常程度(轻、中、重型)与临床疗效(痊愈、未愈)进行比较分析。结果:两组患者EEG异常变化及异常程度与临床疗效均显示明显差异。结论:初治后脑梗塞患者EEG改变能够反映出临床复发的趋势特征。
