Purpose: To determine potential mechanisms of epilepsy in patients with multiple sclerosis (MS).
Methods: Among 402 patients with clinically and radiologically defined MS, including de novo cases, presenting to the Neurology Service, University Hospital of Dijon, we identified 17 with epileptic seizures (4.25%). Among them, the percentage with partial seizures (50%) was greater than that in the reference population.
Results: In most of the patients with MS, plaques were localized in the frontal region, associated with frontal and callosal atrophy, a frontal syndrome, and severe disability status (as assessed by a standard scale). Magnetic resonance imaging (MRI) showed numerous subcortical plaques. Seizures generally were well controlled with antiepileptic drugs (AEDs).
Conclusions: Our data suggest that the subcortical plaques of MS underlie seizure activity in patients with MS and epilepsy.

Astrocytoma is a common type of glioma and a frequent cause of brain tumour-related epilepsy. Although the link between glioma and epilepsy is well established, the precise mechanisms underlying epileptogenesis in astrocytoma remain poorly understood. In this study, we performed proteomic analysis of astrocytoma tissue from patients with and without seizures using mass spectrometry-based techniques.

Biallelic pathogenic variants in cause a fatal autosomal recessive multisystem disorder characterized by recurrent autoinflammation, hypomyelination, progressive neurodegeneration, microcephaly, failure to thrive, liver dysfunction, respiratory chain defects and accumulation of glycogen in skeletal muscle. No missense variants in have been reported to date.We report a 6-year-old boy with microcephaly, global developmental delays, lower limb spasticity with hyperreflexia, epilepsy, abnormal brain MRI, failure to thrive, recurrent fevers and transaminitis.

Elucidating human cerebral cortex function is essential for understanding the physiological basis of both healthy and pathological brain states. We obtained extracellular local field potential recordings from cortical slices of neocortical tissue from refractory epilepsy patients. Multi-electrode recordings were combined with histological information, providing a two-dimensional spatiotemporal characterization of human cortical dynamics in control conditions and following modulation of the excitation/inhibition balance.

Zonisamide exhibits significant pharmacokinetic variability, demanding for the development of population pharmacokinetic (PopPK) models to identify key factors influencing drug disposition. This study aimed to develop and validate a PopPK to optimize zonisamide posology in patients with refractory epilepsy. A total of 114 plasma concentrations of zonisamide, obtained from 64 patients, were used for PopPK model development, employing the nonlinear mixed-effects modelling approach.

Neurocysticercosis (NCC) has been classified as a neglected tropical disease by the World Health Organization (WHO), with the condition being regarded as the most significant parasitic disease affecting the nervous system. Hence, the aim of this study was to conduct a review of previously published case reports on this topic in order to ascertain whether there is an increasing trend of NCC worldwide and evaluate the cases that have been presented. After a comprehensive search of the Web of Science Core Collection using the keywords "neurocysticercosis" and "case reports", studies were selected by applying inclusion criteria.
