Patients with epilepsy may experience psychiatric symptoms preceding the seizure (pre-ictal), following the seizure (post-ictal), independently of seizure occurrence (interictal), or as an expression of the seizure (ictal). Compared to interictal, peri-ictal psychiatric symptoms are less investigated and recognized. However, they contribute substantially to disability and distress among people with epilepsy.The relationship between interictal and periictal symptoms is still largely unknown but it seems that they are intimately related in epilepsy. Greater appreciation and understanding of the periictal period is clinically important, providing a model for understanding basic mechanisms underlying mood and thought disorders and the substrates of cognition, volition, emotion, and consciousness.The present paper is aimed at reviewing major psychiatric symptoms that may occur around the ictus with special attention to clinical descriptions and relationships with interictal psychopathology.

发作期和围发作期精神病理学。

癫痫患者可能会在癫痫发作前（发作前）、发作后（发作后）出现精神症状，与发作的发生无关（发作间期），或表现为发作的表现（发作期）。与发作间期相比，对发作期精神症状的研究和认识较少。然而，它们在很大程度上导致癫痫患者的残疾和痛苦。发作间期和发作期症状之间的关系在很大程度上仍然未知，但它们似乎与癫痫密切相关。更好地了解和理解围发作期在临床上很重要，它为理解情绪和思维障碍的基本机制以及认知、意志、情感和意识的基础提供了一个模型。
