Ictal fear-a relatively rare phenomenon-is a semiological characteristic of epilepsy. Most patients with epilepsy with ictal fear have an epileptic zone in the mesial temporal lobe, which is the classical brain area involved in emotion processing. Herein, we report a case of epilepsy with ictal fear as the first manifestation in a 10-year-old boy. All noninvasive evaluation including scalp video electroencephalography (EEG), magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET-CT) suggested a possible lesion in the left posterior brain region. Stereo-electroencephalography (sEEG) results showed high frequency direct current shift in the left occipital lobe 1 s before the fear manifestation which preceded in 12 s the discharge in the amygdala. This case highlights the epileptic network hypothesis which suggested occipital cortex may play an important role in the early emotional network independently of amygdala activation.
发作性恐惧——一种相对罕见的现象——是癫痫的一种症状学特征。大多数患有发作性恐惧的癫痫患者在颞叶内侧有癫痫病灶,这是参与情绪处理的经典脑区。在此,我们报告一例以发作性恐惧为首发表现的10岁男孩癫痫病例。所有无创评估包括头皮视频脑电图(EEG)、磁共振成像(MRI)和正电子发射断层扫描/计算机断层扫描(PET-CT)均提示左侧后脑区域可能存在病变。立体定向脑电图(sEEG)结果显示,在恐惧表现前1秒左侧枕叶出现高频直流偏移,这比杏仁核放电提前12秒。该病例突出了癫痫网络假说,即枕叶皮质可能在早期情绪网络中独立于杏仁核激活发挥重要作用。
