37 epileptics with routine records without paroxysms were subject to 24 hours mobile long-term EEG registration and independently 24 hours sleep deprivation EEG including hyperventilation and photic stimulation. The anticonvulsive treatment was not changed. In 14 cases we could prove epileptiform discharges (= positive finding) by using both methods, in 13 after sleep derivation (10 at rest, 3 only during hyperventilation) in 7 in the long-term record and in 6 of them both after sleep deprivation and in long-term record. As epileptiform discharges we rated spikes, spikes ans slow waves, epileptic K-complexes, spike and waves and poly spike wave-paroxysms. We refer the small number of positive findings in the mobile long-term EEG mainly to the fact that only 3 EEG canals are disponible until now. Therefore on the one hand it is not definitely possible to distinguish sharp waves from sharp transients physiologically appearing in sleep, on the other hand focal EEG-changes often escape from being recorded.
37例无发作常规记录的癫痫患者接受了24小时动态长期脑电图记录，并独立进行了24小时睡眠剥夺脑电图检查，包括过度换气和光刺激。抗惊厥治疗未改变。14例患者通过两种方法均可证实有癫痫样放电（=阳性结果），13例在睡眠诱发后出现（10例在静息时，3例仅在过度换气时出现），7例在长期记录中出现，其中6例在睡眠剥夺和长期记录后均出现。作为癫痫样放电，我们将棘波、棘波和慢波、癫痫K复合波、棘慢波和多棘波阵发进行了评级。我们将动态长期脑电图中少量的阳性结果主要归因于目前仅有3个脑电图通道可用。因此，一方面，从生理学角度来看，在睡眠中出现的尖锐波与尖锐瞬变波难以明确区分，另一方面，局灶性脑电图变化常常无法被记录到。
