摘要

目的：挠曲性癫痫是一种癫痫性疾病，其癫痫发作是由特定的、可识别的刺激引起的，通常是感觉或认知刺激。在记忆诱发癫痫发作的患者中，记忆是否作为癫痫发作的触发因素或代表其最初的临床表现一直存在争议。方法我们报告了一名25岁的女性，她因回忆特定的自传体记忆而引发反射性癫痫发作。结果利用立体脑电图（sEEG），我们捕捉到了自发性记忆检索引起的反射现象，并确定了诱发癫痫发作的生理记忆网络中的激活模式。结论本病例强调了记忆相关皮层回路与ictogenic机制之间复杂的相互作用，为反射性癫痫中皮层兴奋性的动态景观提供了新的见解。

Experiential reflex epilepsy demonstrated with stereoEEG

Purpose

Reflex epilepsies are epileptic disorders in which seizures are consistently provoked by specific, identifiable stimuli—typically sensory or cognitive. In patients with memory-induced seizures, it has long been debated whether the memory acts as the trigger for the seizure or represents its first clinical manifestation.

Methods

We present the case of a 25-year-old woman with reflex seizures triggered by the recollection of specific autobiographical memories.

Results

Using stereo-electroencephalography (sEEG), we captured the reflex phenomenon induced by a voluntary retrieval of memory and identified activation patterns within physiologic memory networks contributing to seizure initiation.

Conclusion

This case highlights the complex interplay between memory-related cortical circuits, and ictogenic mechanisms, offering new insights into the dynamic landscape of cortical excitability in reflex epilepsies.
