到目前为止,除了医师能目睹患者的发作是否象癫痫以外,脑电图是诊断癫痫的最有用的辅助工具,其他一些辅助诊断方法如CT等可以对发现某些引起癫痫的病因有助,但对患者是否有癫痫则帮助不大,当然只有一次脑电图检查,而患者的癫痫发作很稀少,或已服用相当剂量的药物,脑电图也不一定有阳性发现,如果多次反复检查,加以各种诱发试验和特殊电极的应用,那末脑电图诊断癫痫的阳性率就相当高了。下面对常见的痫样(性)放电作一简介。一般来说,凡是在原来背景电活动的基础上突然发生的高波幅放 Until now, EEG has been the most useful adjunct to diagnosing epilepsy, except that physicians can see if a patient’s seizures are like epilepsy. Other auxiliary diagnostic methods such as CT may help find some of the causes of epilepsy but Of course, there is only one EEG examination, and patients with seizures are rare, or have taken a considerable dose of drugs, EEG does not necessarily have positive findings, if repeatedly repeated examination, To a variety of induced test and the application of special electrodes, then the positive rate of EEG diagnosis of epilepsy is quite high. The following common epileptic (sexual) discharge for a brief introduction. In general, all the sudden fluctuations in the original background based on the electrical amplitude of the release
