To study the short-term effects of vagus nerve stimulation (VNS) on brain activation and cerebral blood flow by using functional magnetic resonance imaging (fMRI).Five patients (three women, two men; mean age, 35.4 years) who were treated for medically refractory epilepsy with VNS, underwent fMRI. All had a nonfocal MRI. The VNS was set at 30 Hz, 0.5-2.0 mA intervals s off, during which fMRI performed. Statistical parametric mapping (SPM) used to determine significant areas or inhibition...
Objective: Qatar is a small country on the Eastern coast of Arabian Peninsula.Its population unique mixture native citizens and immigrants.We aimed to describe features epilepsy in as such information virtually lacking from current literature.Methods: We summarized retrospectively collected 468 patients with seen through national health system adult neurology clinic.Results: Epilepsy was classified focal 65.5% cases generalized 23%.Common causes were follows: stroke (9%), hippocampal...
Cohen syndrome (CS) is a rare multisystem autosomal recessive disorder associated with mutations in VPS13B (vacuolar protein sorting homolog 13B). The NAPB-related neurodevelopmental characterized mainly by early-onset epileptic encephalopathy (EOEE) and NAPB that encodes for SNAP-beta (soluble NSF attachment beta). Here we describe male triplets, clinically presenting the phenotype of subtle but distinctive facial features, intellectual disability, increased body weight, neonatal EOEE,...
The discontinuous patterns in neonatal magnetoencephalographic (MEG) data are quantified with a novel Hilbert phase (HP) based approach. expert neurologists' scores were used as the gold standard. performance of this approach was analyzed using receiver operating characteristic (ROC) curve, and it compared two other approaches, namely spectral ratio (SR) discrete wavelet transform (DWT) that have been proposed for detection EEG. area under ROC curve (AUC) measure. AUCs obtained SR, HP, DWT...
Over a 10-year period, the authors have observed rare but recurring syndrome manifested by delayed, postoperative, progressive decline in level of consciousness to deep coma that is time-limited several days with abrupt awakening. Extensive evaluation and workup demonstrated an abnormality on continuous electroencephalographic monitoring implied nonconvulsive status epilepticus after exclusion structural, perfusion, infectious, or metabolic causes. This state has been very refractory...
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) often presents a history of migraine aura eventual manifestations dementia unrelenting, repeated cerebral vascular insults. Only 6-10% patients CADASIL have been reported to develop seizures, status epilepticus (SE) is exceedingly rare. Here, we describe patient who presented recurrent SE, biopsy diagnosis CADASIL. An 80-year-old woman our hospital three times in two years decreased level...
Objective: This study aimed to determine the effect of reperfusion therapies on occurrence early post-stroke seizures (PSS) in patients with acute ischemic stroke (AIS). Background: Reperfusion are paramount treatment phase. However, their incidence after an AIS remains unclear. Design and Methods: The database at Hamad Medical Corporation was used identify all who received for from 2016 2019. They were matched similar diagnosis, gender, age, severity as measured by National Institutes...
To describe the occurrence and features of Neurocystircercosis (NCC) in Qatar.Qatar has a mixed population natives expats. NCC is not endemic to region, but clinical practice suggests its large numbers.A database was created summarize information retrospectively collected on patients with seen through national health system (HMC) between 2013 2018. We identified demographic disease related variables (clinical manifestations, investigative findings, treatment outcome) for all patients.Out 420...
The fetal magnetoencephalogram (fMEG) is measured in the presence of large interference from maternal and magnetocardiograms (mMCG fMCG). These cardiac interferences can be attenuated by orthogonal projection (OP) technique corresponding spatial vectors. However, OP redistributes fMEG signal among channels also leaves some residuals (partially mMCG fMCG) due to loss stationarity signal. In this paper, we propose a novel way extract localize neonatal spontaneous brain activity using...
To assess the gain in detection of epileptiform abnormalities 24-hour EEG recordings following first seizure.We identified patients who underwent video (VEEG) with "first seizure" as an indication. We noted presence or absence discharges (EDs) VEEG study and latency for appearance such discharges. compared rate EDs during initial 60 min those occurring only later recording.Data from 25 patients, aged 15 to 59, were included. Of 11 EDs, eight (73%) appeared after recording. This equates a 32%...
Objective . To report a case of refractory status epilepticus (SE) as an unusual early manifestation H1N1 influenza infection. Introduction neurological complications have been reported and consist mainly seizures or encephalopathy occurring in children. However, we only found single adult developing complex partial SE with Case Report A 21-year-old previously healthy man was brought to the emergency room (ER) after witnessed generalized tonic clonic seizure (GTCS). He fully alert afebrile...
Abdominal epilepsy is often unrecognised as an condition, particularly in adults. We present a rare adult patient who suffers daily episodes of abdominal pinching pain described lasting for 30 seconds, evolving to loss consciousness. Scalp EEG-video monitoring showed interictal left temporal slowing and frequent epileptiform discharges. Three stereotypical complex partial seizures consistent with her habitual attacks were recorded. Two onset whereas the third one appeared start on right...
Abstract Although eslicarbazepine is an anti‐seizure medication, it may result in seizure worsening if its use complicated by severe hyponatremia, even long time after commencing this medication. The treatment a replacement for another ASM.
We propose a novel method to characterize the spontaneous brain signals using Hilbert phases. The phase of signal exhibits slips when magnitude successive difference exceeds pi. To this end we use standard deviation (sigmaDeltatau) time (Deltatau) between signals. demonstrate application approach neonatal and fetal magnetoencephalographic recorded 151-sensor array identify sensors containing spatial filter sigma(Deltatau) as weights reconstruct
