淺析腦電圖在癲癇病研究中的應用價值

1、.The value of EEG in epilepsy research（淺析腦電圖在癲癇病研究中的應用價值）EEG in epilepsy research in the application of the value of it? The answer is yes. Mainly in the following aspects.腦電圖在癲癇的研究中有應用價值嗎？答案是肯定的。主要表現(xiàn)在以下幾方面。(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）癲癇的病因研究癲癇的病因很復雜，但與遺傳有密切的關系。在癲癇的遺傳學研究中，腦電圖檢查是重要的研究方法之一。在中央腦型癲癇患兒的同胞中，46%有腦電圖的癲癇樣節(jié)律紊亂，是對照組的3.5倍，通過癲癇患兒家系的腦電圖描記，發(fā)現(xiàn)不僅特發(fā)性癲癇與遺傳有關,而且繼發(fā)性癲癇也受遺傳因素的影響。(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）腦電圖與癲癇診斷癲癇的診斷主要依靠

6、臨床表現(xiàn)和腦電圖檢查,然而醫(yī)生很難有機會目睹患兒的發(fā)作經(jīng)過，而病史陳述者又往往描述不準確或不完全，因此準確的臨床資料有時很難得到。而腦電圖可直接記錄患兒的癇樣放電，成為診斷的重要依據(jù)。據(jù)報道，80%以上的癲癇患兒有發(fā)作間期腦電圖異常。隨著新的腦電圖技術的應用，陽性率會越來越高，對癲癇的診斷價值會越來越大。(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

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）腦電圖與癲癇分類盡管癲癇波可見于各型癲癇，但各型癲癇都有其相應的腦電圖特征。如部分性發(fā)作腦電圖異常開始局限于一側(cè)大腦半球之內(nèi)，而全身性發(fā)作異常放電波及兩側(cè)大腦半球；嬰兒痙攣癥表現(xiàn)為高峰失律；大田原綜合征表現(xiàn)為爆發(fā)抑制腦電圖；典型失神表現(xiàn)為彌漫性、對稱性3HZ（赫茲）放電；而小于3HZ的異常放電見于L

9、ennox綜合征,預后與典型失神有天淵之別。(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）腦電圖

10、與癲癇的鑒別診斷有些發(fā)作性疾病，如暈厥、睡眼障礙、癔病等，有時僅靠病史難以區(qū)別，但這些疾病腦電圖大都正常，為鑒別診斷提供了重要依據(jù)。(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）腦電圖對治療的指導作用腦電圖檢查不僅可以確定發(fā)作類型、指導臨床選藥，而且能夠協(xié)助判斷療效，并可作為停藥的參考依據(jù)。在外科治療癲癇時，腦電圖對病灶的定位、確定手術范圍有重要指導意義。(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
