Background And Purpose: Heart rate (HR) change is easily seen in seizures. Tachycardia is frequently seen in temporal lobe epilepsy (TLE), rather than extra temporal lobe epilepsy (XTLE). We report the difference in the HR pattern between TLE and frontal lobe epilepsy (FLE) during peri-ictal period.
Methods: The ECG data, collected during EEG monitoring, was used. To compare the HR pattern between FLE and TLE, we investigated the baseline HR, maximum HR, seizure onset to peak HR, HR change, and the time return to baseline.
Results: A total of 198 seizures (FLE was 115, TLE was 83) were included in this study. The baseline HR (in TLE, 74.9 ± 17.2 and in FLE, 70.7 ± 11.5 bpm), there was no difference between two groups. But the mean duration of the increased HR was more prolonged in TLE group (93.8 ± 54.9 seconds) than the FLE group(39.0 ± 21.4 seconds) (p < 0.001), the time to peak HR of the TLE group (135.1 ± 19.1 seconds) was higher than FLE group (119.3 ± 19.7 seconds) (p = 0.027), and the HR change of the TLE group (60.0 ± 26.3 bpm) was more prominent than that of the FLE group (22.8 ± 26.2 seconds) (p < 0.001). Furthermore, a longer duration of HR increase was seen in that of the TLE group than FLE group.
Conclusions: The HR change of the TLE group was more prominent and prolonged than that of the FLE group. Therefore, the HR change can be a pattern that differentiates TLE from FLE.

Background: The fundamental pathophysiologic understanding of different seizure types in Temporal lobe epilepsy (TLE) remains unclear. This study aimed to assess the distinct alterations of structural network in TLE patients with different seizure types and their relationships with cognitive and psychiatric symptoms.
Methods: Seventy-three patients with unilateral TLE, including 25 with uncontrolled focal to bilateral tonic-clonic seizures (FBTCS), 25 with controlled FBTCS and 23 with focal impaired awareness seizures (FIAS), as well as 26 healthy controls (HC), underwent the diffusion tensor imaging (DTI) scan.

Background: Utilization of transvenous lead extraction/removal (TLE) for the management of cardiac implantable electronic device (CIED)-associated infective endocarditis (IE) remains low.
Objective: To examine the impact of hospital TLE procedural volume on TLE utilization and outcomes for patients with CIED-associated IE.
Methods: Using the Nationwide Readmissions Database, we evaluated 21,545 admissions for patients (mean age 70, 39% female) with CIEDs hospitalized with IE at TLE centres.
Lateralizing Value of Artificial Intelligence-Based Segmentation Software in MRI-Negative Focal Epilepsy.

Department of Neurology, Seoul National University College of Medicine, Seoul, Korea.
Background And Purpose: The magnetic resonance images (MRIs) ability of lesion detection in epilepsy is crucial for a diagnosis and surgical outcome. Using automated artificial intelligence (AI)-based tools for measuring cortical thickness and brain volume originally developed for dementia, we aimed to identify whether it could lateralize epilepsy with normal MRIs.
Methods: Non-lesional 3-Tesla MRIs of 428 patients diagnosed with focal epilepsy, based on semiology and electroencephalography findings, were analyzed.

Objective: Epilepsy is associated with progressive cortical atrophy exceeding normal aging. We aimed to explore longitudinal cortical alterations in patients with temporal lobe epilepsy (TLE) and distinct surgery outcomes.
Methods: We obtained longitudinal T1-weighted MRI data in a well-designed cohort, including 53 operative TLE patients, 23 nonoperative TLE patients, and 23 healthy controls.
