确定癫痫发放源,在CT等形态学上有改变的癫痫病人,一般还易做到。对于影像学无阳性发现的病人,简便、易行、价格低廉的脑电图就起了重要的作用。但是,由于癫痫具有发作性特点,在许多病例中,棘波的发放往往只在发作中或睡眠中,而普通脑电图描记则多在癫痫发作的间歇期,因此影响了对癫痫源的确定。为了克服这种不足,我们对临床上有局限性发作,而普通脑电图不能定位,同时缺乏CT依据的67名患者进行了长时间的脑电监测,以试图提高诊断癫痫和癫痫源确定的阳性率,为临床手术治疗提供可靠的依据。
Determine the source of epilepsy, CT and other morphological changes in epilepsy patients, generally easy to do. For patients with no positive findings in imaging, EEG, which is simple, easy and inexpensive, plays an important role. However, due to the seizure nature of epilepsy, in many cases, spike waves are often issued only during seizures or during sleep, whereas general EEG is more often performed during the seizure period, thus affecting the determination of epilepsy . In order to overcome this deficiency, we have a clinical episode of limitations that the general EEG can not locate and CT-based 67 patients who underwent long-term EEG monitoring in an attempt to improve the diagnosis of epilepsy and epilepsy identified Positive rate, provide a reliable basis for clinical surgical treatment.
