PURPOSE: Localization of seizures in frontal lobe epilepsy using the 10-20 system scalp EEG is often challenging because neocortical seizure can spread rapidly, significant muscle artifact, and the suboptimal spatial resolution for seizure generators involving mesial frontal lobe cortex. Our aim in this study was to determine the value of visual interpretation of 76 channel high density EEG (hdEEG) monitoring (10-10 system) in patients with suspected frontal lobe epilepsy, and to evaluate concordance with MRI, subtraction ictal SPECT co-registered to MRI (SISCOM), conventional EEG, and intracranial EEG (iEEG)...

Ancient Chinese literature has documented that acupuncture possesses efficient therapeutic effects on epilepsy and insomnia. There is, however, little research to reveal the possible mechanisms behind these effects. To investigate the effect of acupuncture on epilepsy and sleep, several issues need to be addressed. The first is to identify the acupoints, which correspond between humans, rats, and mice. Furthermore, the depth of insertion of the acupuncture needle, the degree of needle twist in manual needle acupuncture, and the stimulation parameters for electroacupuncture (EA) need to be determined...

Dyke-Davidoff-Masson syndrome (DDMS) is a rare, but important cause of drug-resistant seizures. Dyke-Davidoff-Masson syndrome is a constellation of clinical features that consists of hemiparesis, seizure, facial asymmetry, and intellectual disability with distinct neuroimaging features. A 27-year-old lady presented to us with drug-resistant epilepsy, hemiparesis, and intellectual disability that necessitated her withdrawal from school. Her brain magnetic resonance imaging (MRI) showed cerebral hemiatrophy, calvarial thickening, and hyperpneumatization of the frontal sinuses consistent with DDMS...

Nocturnal frontal lobe epilepsy (NFLE) is a focal epilepsy with seizures arising mainly during sleep and characterized by complex, often bizarre, motor behavior or sustained dystonic posturing. First described in 1981, it was initially considered a motor disorder of sleep and was named nocturnal paroxysmal dystonia (NPD). The unusual seizure semiology, onset during sleep, and often uninformative scalp EEG and brain MRI make it difficult to distinguish NPD attacks from other non-epileptic nocturnal paroxysmal events, namely parasomnias...

Left and right mesial temporal lobe epilepsy (mTLE) with hippocampal sclerosis (HS) exhibits similar functional and clinical dysfunctions, such as depressive mood and emotional dysregulation, implying that the left and right mTLE may share a common network substrate. However, the convergent anatomical network disruption between the left and right HS remains largely uncharacterized. This study aimed to investigate whether the left and right mTLE share a similar anatomical network. We examined 43 (22 left, 21 right) mTLE patients with HS and 39 healthy controls using diffusion tensor imaging...

Astrocytoma is the most frequent malignancies of the brain. Despite present clinical advancements, median survival time in malignant forms remains poor. Downstream of kinase protein 2 (Dok2) is adaptor protein known to modulate the effect of tyrosine kinase. Previously, Dok2 is shown to be marker of poor prognosis in colorectal and gastric cancer, and reduced levels of Dok2 were reported in lung adenocarcinoma and gastric cancer. The aim of the present study was to evaluate prognostic significance of pDok2 expression in surgically resected astrocytoma tissue samples...

Structural and functional abnormalities in the thalamocortical network in primary generalized epilepsies or mesial temporal lobe epilepsy have recently been identified by voxel-wise analyses of neuroimaging. However, evidence is needed regarding the profiles of the thalamocortical network in patients with secondarily generalized seizures from focal neocortical sources. We used high-resolution T1-weighted, diffusion-tensor and resting-state functional MR imaging (rs-fMRI) to examine 16 patients with secondarily generalized extratemporal lobe seizures and 16 healthy controls...
