Abstract

Purpose: This work investigates the presence of common anatomic regions associated with interictal activity in patients with hyperkinetic seizures type I by means of concurrent electroencephalography and functional magnetic resonance imaging.

Methods: Six patients with hyperkinetic seizures type I were evaluated with video-EEG and electroencephalography and functional magnetic resonance imaging in the context of their presurgical evaluation. Statistical Parametric Mapping was used to perform a correlation study between the occurrence of interictal spikes on EEG and suprathreshold blood oxygen level-dependent changes in the whole-brain volume.

Results: In all patients, Statistical Parametric Mapping revealed suprathreshold blood oxygen level-dependent clusters in the mesial anterior frontal areas, including the rostral mesial superior frontal gyrus and the anterior cingulate, associated with the patients' typical interictal activity.

Conclusions: The electroencephalography and functional magnetic resonance imaging findings contribute to our understanding of hyperkinetic seizures type I semiology generation and can inform stereo-EEG targeting for surgical planning in refractory cases.

发作间期脑电图和功能磁共振成像揭示了过度动眼神经症I型患者的中前额叶结构受累。

目的：本研究通过同时进行脑电图和功能磁共振成像检查，研究 I 型过度运动性癫痫患者发作间期活动相关的常见解剖区域：在对六名I型过度运动性癫痫发作患者进行手术前评估时，对他们进行了视频脑电图、脑电图和功能磁共振成像评估。采用统计参数映射法对脑电图上发作间期尖峰的出现与阈上血氧水平依赖性全脑容量变化之间的相关性进行了研究：在所有患者中，统计参数图谱显示，阈上血氧水平依赖性集群位于额叶中前部区域，包括额叶上回喙内侧和扣带回前部，与患者典型的发作间期活动有关：脑电图和功能磁共振成像的研究结果有助于我们了解超运动性癫痫 I 型的半身结构，并可为难治性病例的手术规划提供立体脑电图定位信息。
