Impact of post-traumatic stress disorder on epileptogenic networks: a functional connectivity study.
Sci Rep

Post-traumatic stress disorder (PTSD) is more common in patients with drug-resistant epilepsy. Some of these patients experience PTSD due to early psychotraumatic events. This study aims to assess the influence of PTSD on interictal functional connectivity using stereoelectroencephalography (SEEG) recordings in patients with temporal lobe DRE (TDRE).

Temporal lobe epilepsy (TLE) can cause different types of memory impairments. Here, we report a case of immediate improvement of memory impairment following antiepileptic drug (AED) treatment in a patient with TLE with amygdala enlargement (TLE-AE), who rapidly developed recurrence. The patient was a man in his 60s whose family members complained of his amnesia.

Center for Pediatric Neurology and Neurorehabilitation, Epilepsy Center for Children and Adolescents, Schoen Clinic Vogtareuth, Vogtareuth, Germany.
Objective: To investigate the frequency of epileptiform discharges associated with self-limited focal epilepsy (EDSelFEC) in children who have undergone a hemispherotomy and to evaluate whether patients with coexistence of EDSelFEC and structural hemispheric epilepsies differ from patients without coexistence of EDSelFEC and whether there are differences between the two groups with regard to preoperative management and postoperative outcome.
Methods: Data on 131 children who underwent a hemispherotomy between January 1999 and January 2015 were retrieved from the Epilepsy center's epilepsy surgery database. Children with EDSelFEC were compared with children without EDSelFEC with respect to epileptogenic hemispheric pathology, family history, age at epilepsy onset, timing of surgery, lesion laterality, preoperative cognitive function, response to sodium channel blocker antiepileptic medication, and surgical outcome.
Brain Hypertrophy in Patients With Mesial Temporal Lobe Epilepsy With Hippocampal Sclerosis and Its Clinical Correlates.

January 2025
Department of Neurology, Clinical Neuroscience Center, University Hospital and University of Zurich, Zurich, Switzerland.
Background And Objectives: Mesial temporal lobe epilepsy (mTLE) is generally associated with focal brain atrophy, but little knowledge exists on possible disease-related hypertrophy of brain structures. We hypothesized that repeated seizures or adaptive plasticity may lead to focal brain hypertrophy and aimed to investigate associated clinical correlates.
Methods: In this cohort study, we included patients with mTLE undergoing detailed epilepsy evaluations and matched healthy volunteers (HVs) from 2 tertiary centers (discovery and validation cohorts).
Lasting and extensive consequences of left mesial temporal lobe seizures on electrical cortical activity.

Department of Clinical Neurophysiology, Lille University Hospital, Lille 59037, France; INSERM U1172, LilNCog - Lille Neuroscience & Cognition, Lille 59000, France.
Background And Objectives: Focal epilepsies disrupt long-range networks with seizure recurrence driving both regional and global alterations in connectivity networks. While prior studies have focused on the interictal consequences, limited data exist on the direct aftermath of focal seizures. We hypothesize that mesial temporal lobe seizures lead to enduring cortical disorganization.
