Complexity of Multi-Channel Electroencephalogram Signal Analysis in Childhood Absence Epilepsy. [PDF]

PLoS ONE, 2015
Absence epilepsy is an important epileptic syndrome in children. Multiscale entropy (MSE), an entropy-based method to measure dynamic complexity at multiple temporal scales, is helpful to disclose the information of brain connectivity.

Functional Segregation of Epileptogenicity within the Human Amygdala

Annals of Neurology, EarlyView.
Objective In temporal lobe epilepsy (TLE), the amygdala in the epileptogenic network is underestimated compared to other regions such as the hippocampus. Recent advances in anatomical neuroimaging and stereoelectroencephalography (SEEG) signal analyses could help better understand the involvement of the different amygdala nuclei in the genesis of ...

Field effects and ictal synchronization: insights from in homine observations.

Frontiers in Human Neuroscience, 2013
It has been well established in animal models that electrical fields generated during inter-ictal and ictal discharges are strong enough in intensity to influence action potential firing threshold and synchronization.

The ictal wavefront is the spatiotemporal source of discharges during spontaneous human seizures

Nature Communications, 2016
The extensive distribution and simultaneous termination of seizures across cortical areas has led to the hypothesis that seizures are caused by large-scale coordinated networks spanning these areas. This view, however, is difficult to reconcile with most

Development and Retrospective Application of Novel Outcome Measure: Sturge–Weber Syndrome Acute Crisis (SWAC) Index

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Sturge–Weber syndrome (SWS) symptoms frequently overlap in neurological acute crises (ACs) presenting with seizures, stroke‐like episodes (SLE), and headaches. Recent efforts to develop a prospective drug trial highlighted the need for a new outcome measure capable of quantifying these symptoms during an SWS AC.

Resolution of generalized tonic seizures following focal ablative or resective surgery

Epileptic Disorders, EarlyView.
Abstract Objective Focal brain lesions may underlie generalized tonic seizures, as seen in Lennox–Gastaut syndrome, by engaging bilateral neural networks. However, this seizure type is often not considered surgically remediable. Here, we describe the resolution of apparent electroclinically classic generalized tonic seizures in children originating ...

Mesial temporal lobe epilepsy with hippocampal sclerosis: Seizure, neuropsychological, and quality of life outcomes of 100 patients treated with trans‐anterior T1 selective amygdalohippocampectomy

Epileptic Disorders, EarlyView.
Abstract Objective For mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE with HS), laser interstitial thermal therapy has recently been increasingly used. At our institute, however, selective amygdalohippocampectomy by a trans‐anterior T1 subpial approach (trans‐anterior T1 SAH) has been used for MTLE with HS. Here, we examined the seizure,

Statistical voxel-wise analysis of ictal SPECT reveals pattern of abnormal perfusion in patients with temporal lobe epilepsy Análise estatística baseada em voxel do SPECT ictal revela um padrão de alteração perfusional em pacientes com epilepsia de lobo temporal

Arquivos de Neuro-Psiquiatria, 2005
OBJECTIVE: To investigate the pattern of perfusion abnormalities in ictal and interictal brain perfusion SPECT images (BSI) from patients with temporal lobe epilepsy (TLE). METHOD: It was acquired interictal and ictal BSI from 24 patients with refractory

The usefulness of intraoperative electrocorticography (iECoG) in pediatric temporal lobe epilepsy surgery

Epileptic Disorders, EarlyView.
Abstract Objective This study aimed to evaluate the usefulness of intraoperative electrocorticography (iECoG) in providing a more accurate surgical strategy, thereby yielding seizure freedom following resective surgery in children with temporal lobe epilepsy (TLE).
