PURPOSE Psychogenic non-epileptic seizures (PNES) are paroxysmal behaviors that resemble epileptic seizures but lack abnormal electrical activity. Some neuroimaging studies have reported that PNES exhibits aberrant functional connectivity in specific brain networks. Thus, advanced neuroimaging technologies may aid clinical diagnosis and treatment of PNES.(More)
PURPOSE Simultaneous electroencephalography/functional magnetic resonance imaging (EEG/fMRI) recording can noninvasively map in the whole brain the hemodynamic response following an interictal epileptic discharge. EEG/fMRI is gaining interest as a presurgical evaluation tool. This study aims to determine how hemodynamic responses related to epileptic(More)
Psychogenic non-epileptic seizures (PNES) are paroxysmal behaviors that resemble epileptic seizures but lack abnormal electrical activity. Recent studies suggest aberrant functional connectivity involving specific brain regions in PNES. Little is known, however, about alterations of topological organization of whole-brain functional and structural(More)
BACKGROUND Patients with temporal lobe epilepsy are at high risk for comorbid depression, and it is hypothesized that these two diseases are share common pathogenic pathways. We aimed to characterize regional brain activation in treatment-naïve temporal lobe epilepsy patients with depressive symptoms and compare the results to epilepsy patients without(More)
Although various imaging studies have focused on detecting the cerebral function underlying psychogenic non-epileptic seizures (PNES), the nature of PNES remains poorly understood. In this study, we combined the resting state fMRI with fractional amplitude of low-frequency fluctuations (fALFF) and functional connectivity based on the seed voxel linear(More)
BACKGROUND Many publications have addressed the problem of weight gain and endocrine abnormalities in patients treated with sodium valproate (VPA). However, the presence of metabolic syndrome (MetS) among obese patients with epilepsy on VPA has received little attention. METHODS Thirty-six patients receiving VPA monotherapy were included in this study to(More)
Neuroimaging studies have demonstrated that psychogenic nonepileptic seizures (PNES) are characterized by unstable cognitive-emotional and motor system, which is engaged in hyperactivity of limbic regions and sensorimotor area. The insula, which is a part of the limbic system, includes various subregions with some distinct connectivity patterns separately.(More)
There is evidence that focal epilepsy may involve the dysfunction of a brain network in addition to the focal region. To delineate the characteristics of this epileptic network, we collected EEG/fMRI data from 23 patients with frontal lobe epilepsy. For each patient, EEG/fMRI analysis was first performed to determine the BOLD response to epileptic spikes.(More)
INTRODUCTION Blood oxygenation level-dependent (BOLD) signal changes at the time of interictal epileptic discharges (IEDs) identify their associated vascular/hemodynamic responses. BOLD activations and deactivations can be found within the epileptogenic zone but also at a distance. Source imaging identifies electric (ESI) and magnetic (MSI) sources of IEDs,(More)
PURPOSE This study aimed to compare the monotherapeutic efficacies of levetiracetam (LEV) and valproic acid (VPA) in a cohort of newly diagnosed children with typical benign childhood epilepsy with centrotemporal spikes (BECTS). METHODS A total of 56 children with typical BECTS were retrospectively reviewed in the analyses. Thirty-three children received(More)
