Autonomic and visceral phenomena are well-known manifestations of epileptic seizures, but recurrent vomiting as ictal epileptic events are less known. Three patients with ictus emeticus, i.e. with nausea and vomiting as their main ictal symptoms, are described. Vomiting is a complex symptom preceded by several phenomena in the gastrointestinal tract and transmitted by the vagal nerve to the vomiting centre in the lateral reticular formation of the medulla oblongata. This autonomic centre in the brain stem is influenced by several cerebral structures. There is both experimental and clinical evidence to support the hypothesis that epileptic disturbances in the insula and the mesial temporal structures are responsible for ictus emeticus.
自主神经和内脏现象是癫痫发作的常见表现，但以发作性癫痫事件形式出现的反复呕吐却鲜为人知。本文描述了3例以呕吐为发作症状的患者，即以恶心和呕吐作为主要发作症状。呕吐是一种复杂的症状，在胃肠道有多种现象先于呕吐出现，并通过迷走神经传递至延髓外侧网状结构中的呕吐中枢。脑干中的这个自主神经中枢受多个脑结构的影响。有实验和临床证据支持这样的假说，即岛叶和内侧颞叶结构的癫痫性紊乱是发作性呕吐的病因。
