Abstract

In a retrospective study, the occurrence of epileptiform activity (EA) in routine EEG records of epileptic patients was investigated. Data were obtained from 1078 EEGs of 373 patients (199 men and 174 women; aged 17-87 (mean 34.2 +/-14.7)). The percentage of 38% of patients with EA in a single EEG could be increased to 77% by repeated records. After the 5th record however, the gain in new information decreased remarkably. No differences between seizure types could be detected. There was a relationship between EA and nonspecific EEG abnormalities. High EA rates were found for short time intervals since last seizure, young patients, long durations of the seizure disorder and for high seizure frequencies.

摘要

在一项回顾性研究中，对癫痫患者常规脑电图记录中癫痫样活动（EA）的发生情况进行了调查。数据来自373例患者的1078份脑电图（199名男性和174名女性；年龄17 - 87岁（平均34.2±14.7岁））。单次脑电图中EA患者的比例为38%，通过重复记录可增至77%。然而，在第5次记录后，新信息的增加显著减少。未发现发作类型之间存在差异。EA与非特异性脑电图异常之间存在关联。在距上次发作时间间隔短、年轻患者、癫痫病程长以及癫痫发作频率高的情况下，发现EA发生率较高。
