Septo-optic dysplasia (SOD) is a rare disorder associated with optic nerve hypoplasia, pituitary abnormalities and agenesis/dysgenesis of midline brain structures including the septum pellucidum and corpus callosum. Though sometimes associated with drug-resistant epilepsy, this association has not been well studied. We report six SOD patients with associated malformation of cortical development (MCD) and drug-resistant epilepsy who underwent video-EEG telemetry at our centre between 1998 and 2016 for drug-resistant epilepsy. Three then underwent surgery; right temporal neocortical resection, right functional hemispherectomy and placement of a vagus nerve stimulator. Clinical findings and the patients' ultimate courses are discussed.

Objectives: Our study aimed to compare signal characteristics of subdural electrodes (SDE) and depth stereo EEG placed within a 5-mm vicinity in patients with drug-resistant epilepsy. We report how electrode design and placement collectively affect signal content from a shared source between these electrode types.
Methods: In subjects undergoing invasive intracranial EEG evaluation at a surgical epilepsy center from 2012 to 2018, stereo EEG and SDE electrode contacts placed within a 5-mm vicinity were identified.

Epilepsy is a complex neurological disorder characterized by recurrent seizures affecting millions of people worldwide. Despite advances in drug therapy, a significant proportion of patients remain resistant to conventional antiepileptic drugs (AEDs) due to challenges such as impermeability of the blood-brain barrier (BBB), multidrug resistance, and multifaceted epileptogenesis. Nanotechnology offers promising strategies to overcome these barriers by enhancing drug delivery across the BBB, improving target specificity and minimizing systemic side effects.

Lennox-Gastaut syndrome (LGS) is a severe developmental and epileptic encephalopathy characterized by multiple drug-resistant seizure types, cognitive impairment, and distinctive electroencephalographic patterns. Neuromodulation techniques, including vagus nerve stimulation (VNS), deep brain stimulation (DBS), and responsive neurostimulation (RNS), have emerged as important treatment options for patients with LGS who do not respond adequately to antiseizure medications. This review, developed with input from the Pediatric Epilepsy Research Consortium (PERC) LGS Special Interest Group, provides practical guidance for clinicians on the use of these neuromodulation approaches in patients with LGS.

Background: Stereoelectroencephalography (SEEG) is a common diagnostic surgical procedure for patients with medically refractory epilepsy. We aimed to describe our initial experience with the recently released NeuroOne Evo SEEG electrode product (Zimmer Biomet, Warsaw, IN) and review technical specifications for other currently approved depth SEEG electrodes.
Methods: We performed a record review on the first five patients implanted with NeuroOne Evo SEEG electrode product using the robotic stereotactic assistance robot platform and described our surgical technique in detail.
