Topographic distribution of seizure patterns in patients with absence epilepsy

, 2022
Background: Absence seizures, which are also known as petit mal seizures, are the most common type of seizures in pediatric epilepsy. They appear in several types of epilepsy and are characterized by impaired consciousness and 3-Hz spike-and-slow-wave ...

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

MRI volumetry shows increased anterior thalamic volumes in patients with absence seizures

, 2015
The interaction between thalamus and cortex appears to be critical to the pathophysiology of idiopathic generalized epilepsies (IGEs). The objective of this study was to investigate thalamic volumes of a group of patients with IGEs using high-resolution ...

Periventricular Heterotopia and Absence Epilepsy

Pediatric Neurology Briefs, 1999
A 7-year-old child with absence seizures and a 3-Hz generalized and occasional focal, spike-and-wave EEG pattern, responsive to treatment with valproic acid, had an MRI with periventricular nodular heterotopias, primarily right sided.

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Electroclinical Features of Absence Epilepsy

Pediatric Neurology Briefs, 2006
Clinical and EEG features of absence seizures in 47 children with newly diagnosed, untreated childhood absence epilepsy (CAE) were analyzed using video-EEG recordings, in a study at University of Otago, Wellington, New Zealand; British Columbia Children ...

The Impact of Glutamatergic Synapse Dysfunction in the Corticothalamocortical Network on Absence Seizure Generation

Frontiers in Molecular Neuroscience, 2022
Childhood absence epilepsy (CAE) is the most common pediatric epilepsy affecting 10–18% of all children with epilepsy. It is genetic in origin and the result of dysfunction within the corticothalamocortical (CTC) circuitry.

The involvement of limbic structures in typical and atypical absence epilepsy

, 2013
Typical and atypical seizures of absence epilepsy are thought to be generated by a rhythmogenic interplay between the cortex and the thalamus. However, the question remains as to which other subcortical and extrathalamic structures are involved in the ...

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Contributions of Magnetoencephalography to Understanding Mechanisms of Generalized Epilepsies: Blurring the Boundary Between Focal and Generalized Epilepsies?

Frontiers in Neurology, 2022
According to the latest operational 2017 ILAE classification of epileptic seizures, the generalized epileptic seizure is still conceptualized as “originating at some point within and rapidly engaging, bilaterally distributed networks.” In contrast, the ...
