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.
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.
