Abstract

In clinical practice, epileptic seizures with focal onset and subsequent generalised motor involvement are referred to as secondarily generalised seizures. The purpose of this study was to investigate the degree of electrophysiological generalisation in seizures that are clinically secondarily generalised. Intracranial EEG recordings of secondarily generalised tonic-clonic seizures were visually and quantitatively analysed for the presence of epileptiform activity. In 24 (26%) of 93 seizures recorded from 17 (27%) of 64 patients, intracranial EEG channels were found that never recorded epileptiform activity during secondarily generalised tonic-clonic seizures. Our results demonstrate that seizures that are secondarily generalised clinically are not always generalised electrophysiologically. This may have therapeutic implications.

摘要

在临床实践中,局灶性起病并随后出现全身性运动受累的癫痫发作被称为继发性全身性发作。本研究的目的是调查临床诊断为继发性全身性发作的癫痫发作的电生理泛化程度。对继发性全身性强直-阵挛发作的颅内脑电图记录进行了视觉和定量分析,以检测癫痫样活动的存在。在64例患者中的17例(27%)记录的93次发作中,有24次(26%)发作的颅内脑电图通道在继发性全身性强直-阵挛发作期间从未记录到癫痫样活动。我们的结果表明,临床诊断为继发性全身性发作的癫痫发作在电生理上并不总是全身性的。这可能具有治疗意义。
