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)
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 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)
Antiepileptic drugs-induced Stevens-Johnson syndrome (SJS) is a life-threatening severe cutaneous adverse reaction. Recent studies in Thailand and Taiwan showed a significant association between phenytoin (PHT)-induced SJS and human leucocyte antigen HLA-B*1502 allele. Although the US FDA had issued an alert to clinicians, insufficient information is(More)
Antiepileptic drugs including lamotrigine (LTG) and carbamazepine (CBZ) are among the most common causes of cutaneous adverse reactions (cADRs). Human leukocyte antigen (HLA)-B*1502 has been strongly associated with CBZ-induced Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). To investigate this relationship, we performed high-resolution HLA(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)
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)
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)
Intrinsic connectivity analysis provides an original way for evaluating functional impairments in epilepsy. Disturbances in the salience network (SN) have been positing an important interplay in disorders of consciousness and attention. This study aims to assess the intrinsic connectivity of the SN in childhood absence epilepsy (CAE). Resting state fMRI was(More)
Activation detection in functional Magnetic Resonance Imaging (fMRI) typically assumes the hemodynamic response to neuronal activity to be invariant across brain regions and subjects. Reports of substantial variability of the morphology of blood-oxygenation-level-dependent (BOLD) responses are accumulating, suggesting that the use of a single generic model(More)
