Invasive epilepsy surgery evaluation [PDF]

, 2016
Intracranial EEG (iEEG) recordings are widely used for the work up of pharmacoresistant epilepsy. Different iEEG recording techniques namely subdural grids, strips, depth electrodes and stereoencephalography (SEEG) are available with distinct limitations

Case Report: Implementation of stereoelectroencephalography in Kazakhstan: early experience in surgical planning for drug-resistant epilepsy

Frontiers in Human Neuroscience
IntroductionThis clinical report describes the management of a 32-year-old patient with a long-standing history of drug-resistant epilepsy. It uniquely illustrates how stereoelectroencephalography (SEEG) played a significant role in the presurgical ...

Epileptogenicity of Cortical Dysplasias and Tumors

Pediatric Neurology Briefs, 2009
The epileptogenic characteristic of focal cortical dysplasias and dysembryoplastic neuroepithelial tumors explored by depth electrodes and stereoelectroencephalography is quantified using an epileptogenicity index, in a study of 36 patients with focal ...

Cortical Connectivity Response to Hyperventilation in Focal Epilepsy: A Stereo-EEG Study

Applied Sciences
Hyperventilation (HV) is an activation technique performed during clinical practices to trigger epileptiform activities, supporting the neurophysiological evaluation of patients with epilepsy. Although the role of HV has often been questioned, especially

Connectome-based disentangling of epilepsy networks from insular stereoelectroencephalographic leads

Frontiers in Neurology
ObjectiveEpilepsy is considered as a network disorder of interacting brain regions. The propagation of local epileptic activity from the seizure onset zone (SOZ) along neuronal networks determines the semiology of seizures.

Interictal Network Dynamics in Paediatric Epilepsy Surgery [PDF]

, 2023
Epilepsy is an archetypal brain network disorder. Despite two decades of research elucidating network mechanisms of disease and correlating these with outcomes, the clinical management of children with epilepsy does not readily integrate network ...

Lesion detection in epilepsy surgery: Lessons from a prospective evaluation of a machine learning algorithm [PDF]

, 2023
AIM: To evaluate a lesion detection algorithm designed to detect focal cortical dysplasia (FCD) in children undergoing stereoelectroencephalography (SEEG) as part of their presurgical evaluation for drug-resistant epilepsy. METHOD: This was a prospective,

Proportion of resected seizure onset zone contacts in pediatric stereo-EEG-guided resective surgery does not correlate with outcome [PDF]

, 2022
Objective: We aimed to determine whether the proportion of putative seizure onset zone (SOZ) contacts resected associates with seizure outcome in a cohort of children undergoing stereoelectroencephalography (SEEG)-guided resective epilepsy surgery ...

Responsive Neurostimulation System (RNS) in setting of cranioplasty and history of multiple craniotomies

Interdisciplinary Neurosurgery, 2016
Introduction: Stereoelectroencephalography (SEEG) and subdural grids (SDG) are both effective options for localizing the ictal onset zone in patients with frequent seizures.

Visual and semiautomated evaluation of epileptogenicity in focal cortical dysplasias - An intracranial EEG study [PDF]

, 2016
INTRODUCTION: The aim of the study was the evaluation of the added value of depth to subdural electrodes in delineating epileptogenicity of focal cortical dysplasias (FCDs) and to test the Epileptogenicity Index (EI) in this setting. MATERIAL AND METHODS:
