浅析脑电图在癫痫病研究中的应用价值

1、.The value of EEG in epilepsy research（浅析脑电图在癫痫病研究中的应用价值）EEG in epilepsy research in the application of the value of it? The answer is yes. Mainly in the following aspects.脑电图在癫痫的研究中有应用价值吗？答案是肯定的。主要表现在以下几方面。(1) The of epilepsy etiology of epilepsy etiology is complex, but has a close relationship wi

2、th genetic. In the study of the genetics of epilepsy, EEG is one of the important research method. Compatriots in the central brain epileptic children, 46% had EEG epileptiform dysrhythmia, is 3.5 times that of the control group, the EEG by families of children with epilepsy and found that not only

3、related to idiopathic epilepsy and genetic and secondary epilepsy also influenced by genetic factors.（1）癫痫的病因研究癫痫的病因很复杂，但与遗传有密切的关系。在癫痫的遗传学研究中，脑电图检查是重要的研究方法之一。在中央脑型癫痫患儿的同胞中，46%有脑电图的癫痫样节律紊乱，是对照组的3.5倍，通过癫痫患儿家系的脑电图描记，发现不仅特发性癫痫与遗传有关,而且继发性癫痫也受遗传因素的影响。(2) EEG epilepsy diagnosis of epilepsy diagnosis relies

4、 on clinical manifestations and EEG, however, doctors have little chance witnessed children with onset after history presenter is often described inaccurate or incomplete, so accuratethe clinical data are sometimes difficult to obtain. EEG can be recorded directly to children with epileptiform disch

5、arges become an important basis for diagnosis. According to reports, more than 80% of children with epilepsy interictal EEG abnormalities. With the new EEG technology applications, the positive rate is getting higher and higher, the the epilepsy diagnostic value will keep rising.（2）脑电图与癫痫诊断癫痫的诊断主要依靠

6、临床表现和脑电图检查,然而医生很难有机会目睹患儿的发作经过，而病史陈述者又往往描述不准确或不完全，因此准确的临床资料有时很难得到。而脑电图可直接记录患儿的痫样放电，成为诊断的重要依据。据报道，80%以上的癫痫患儿有发作间期脑电图异常。随着新的脑电图技术的应用，阳性率会越来越高，对癫痫的诊断价值会越来越大。(3) classification of EEG and epilepsy epileptic be found in various types of epilepsy, but has various types of epilepsy EEG features. Such as par

7、tial seizures EEG abnormality limited to one side of the cerebral hemispheres, abnormal discharge spread to both sides of the brain hemispheres and generalized seizures; the infantile spasms peak imperfectly; the Otawara syndrome showed a burst suppression EEG; the typical absence showed diffuse, sy

8、mmetry 3HZ (Hz) discharge; while less than 3HZ abnormal discharge seen in the Lennox syndrome, prognosis and typical absence a world of difference.（3）脑电图与癫痫分类尽管癫痫波可见于各型癫痫，但各型癫痫都有其相应的脑电图特征。如部分性发作脑电图异常开始局限于一侧大脑半球之内，而全身性发作异常放电波及两侧大脑半球；婴儿痉挛症表现为高峰失律；大田原综合征表现为爆发抑制脑电图；典型失神表现为弥漫性、对称性3HZ（赫兹）放电；而小于3HZ的异常放电见于L

9、ennox综合征,预后与典型失神有天渊之别。(4) Some of the EEG and differential diagnosis of epilepsy episodic disease, such as syncope, sleepy obstacles, hysteria sometimes history of indistinguishable alone, but these diseases are mostly normal EEG, and provides an important basis for the differential diagnosis.（4）脑电图

10、与癫痫的鉴别诊断有些发作性疾病，如晕厥、睡眼障碍、癔病等，有时仅靠病史难以区别，但这些疾病脑电图大都正常，为鉴别诊断提供了重要依据。(5) the guiding role EEG EEG of treatment can not only determine the type of seizure, guiding clinical drug selection, and can help determine the efficacy, can be used as the basis of the withdrawal of the reference. Positioning in th

11、e surgical treatment of epilepsy, EEG lesions to determine the extent of the operation of important guiding significance.（5）脑电图对治疗的指导作用脑电图检查不仅可以确定发作类型、指导临床选药，而且能够协助判断疗效，并可作为停药的参考依据。在外科治疗癫痫时，脑电图对病灶的定位、确定手术范围有重要指导意义。(6) the EEG with epilepsy prognosis is generally believed that the the the EEG backgro

12、und wave normal good prognosis background wave abnormalities and epileptiform discharges poor prognosis. Diffuse 3Hz spike and wave good prognosis, while the performance of slow spike and wave a poor prognosis. There are the temporal central spikes and easily sleep-inducing prognosis is good, one side or both sides of the temporal spikes poor prognosis. Burst suppression and peak disability law EEG shows poor prognosis. Age burst suppression the EEG peak imperfectly, or slow spike and wave from the peak imperfectly, t
