Abstract

This review aimed to characterize the clinical semiology and anatomical correlates of seizures originating in the basal temporal region, an underrecognized epilepsy subtype, and to identify features that distinguish it from other forms of temporal lobe epilepsies (TLE). We performed a systematic review of the literature following PRISMA guidelines. The search included terms related to the basal temporal region (e.g., fusiform gyrus and rhinal cortex) and epilepsy, encompassing clinical, anatomical, and neurophysiological studies. Studies with video-EEG monitoring, SEEG evaluations, and surgical outcomes were prioritized. Semiological features, imaging findings, and post-surgical outcomes were extracted and analyzed. Fifteen studies encompassing 83 patients were analyzed. Most cases involved MRI-detectable lesions. Findings revealed that basal temporal seizures frequently present with language disturbances, motor phenomena, and less pronounced emotional and sensory signs compared to other TLE forms. SEEG identified epileptogenic zones predominantly in the fusiform gyrus, rhinal cortices, and parahippocampal region. Post-surgical outcomes revealed 57% of patients achieving Engel Class I results after 1 year, highlighting the potential benefits of accurate diagnosis and intervention. However, diagnostic challenges persist due to overlapping with other TLE subtypes, emphasizing the importance of advanced imaging and SEEG. Further studies are needed to refine diagnostic criteria and improve understanding of the functional implications of basal temporal epilepsies.

基底颞区癫痫发作的临床和解剖学特征:系统综述。
本综述旨在描述起源于基底颞区(一种未被认识的癫痫亚型)的癫痫发作的临床符号学和解剖学相关性,并确定其与其他形式的颞叶癫痫(TLE)的区别。我们按照PRISMA指南对文献进行了系统回顾。搜索包括与基底颞区(如梭状回和鼻皮质)和癫痫相关的术语,包括临床、解剖和神经生理学研究。优先考虑视频脑电图监测、SEEG评估和手术结果的研究。提取并分析符号学特征、影像学表现和术后结果。我们分析了包括83名患者在内的15项研究。大多数病例涉及mri可检测的病变。研究结果显示,与其他TLE形式相比,基底颞叶癫痫常伴有语言障碍、运动现象和较不明显的情绪和感觉体征。SEEG发现癫痫发生区主要在梭状回、鼻皮质和海马旁区。术后结果显示,57%的患者在1年后达到Engel I级结果,突出了准确诊断和干预的潜在益处。然而,由于与其他TLE亚型重叠,诊断挑战仍然存在,强调了先进成像和SEEG的重要性。需要进一步的研究来完善诊断标准和提高对基底颞叶癫痫功能影响的理解。

期刊介绍: Epileptic Disorders is the leading forum where all experts and medical studentswho wish to improve their understanding of epilepsy and related disorders can share practical experiences surrounding diagnosis and care, natural history, and management of seizures. Epileptic Disorders is the official E-journal of the International League Against Epilepsy for educational communication. As the journal celebrates its 20th anniversary, it will now be available only as an online version. Its mission is to create educational links between epileptologists and other health professionals in clinical practice and scientists or physicians in research-based institutions. This change is accompanied by an increase in the number of issues per year, from 4 to 6, to ensure regular diffusion of recently published material (high quality Review and Seminar in Epileptology papers; Original Research articles or Case reports of educational value; MultiMedia Teaching Material), to serve the global medical community that cares for those affected by epilepsy.
