Epilepsy, seizure

Amara Krag, Gregory L Holmes
Infantile spasms, one of the catastrophic epilepsies, can be a diagnostic challenge since the clinical manifestations may be subtle and may mimic benign conditions. Because of the rarity of the condition, primary care physicians and pediatricians may never see a case of infantile spasms during their career and may be unfamiliar with the seizure semiology. This is a serious issue since there is evidence that early diagnosis and treatment may improve outcome. Patients and families are increasingly using the internet more than their physician as a source of medical information about epilepsy...

PURPOSE: In patients with epilepsy (PWE), relationships between depression, epilepsy characteristics, and cognitive aspects are complex. This study aimed to assess the occurrence of possible major depressive episode in PWE and to verify whether it is associated with the clinical aspects of the disease and cognition. METHODS: Two hundred consecutive PWE with a mean age and standard deviation of 47.6 (±15.1) years were included in the study. We determined whether their Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) scores were associated with their clinical, cognitive, and QOLIE-31 aspects using a significance level of 5% (p<0...

PURPOSE: To determine the agreement between five different methods of ictal EEG source imaging, and to assess their accuracy in presurgical evaluation of patients with focal epilepsy. It was hypothesized that high agreement between methods was associated with higher localization-accuracy. METHODS: EEGs were recorded with a 64-electrode array. Thirty-eight seizures from 22 patients were analyzed using five different methods phase mapping, dipole fitting, CLARA, cortical-CLARA and minimum norm...

PURPOSE: To evaluate electroencephalographic (EEG) differences among syndromes in genetic generalized epilepsy (GGE) based on quantified data. METHODS: 24-hour ambulatory EEGs were recorded in consecutive patients diagnosed with GGE. All epileptiform EEG abnormalities were quantified into density scores (total duration of epileptiform discharges per hour). We conducted one-way analysis of variance (ANOVA) to find out differences in EEG density scores among the syndromes...

INTRODUCTION: Brief potentially ictal rhythmic discharges (B(I)RDs) have been described in neonates and critically ill adults, and their association with seizures has been demonstrated. Their significance in non-critically ill adults remains unclear. We aimed to investigate their prevalence, electrographic characteristics and clinical significance. METHODS: We identified adult patients with B(I)RDs who received long term EEG recordings either in the epilepsy monitoring unit or in the ambulatory setting...

Mutations in GABAA receptor subunit genes are frequently associated with epilepsy, and nonsense mutations in GABRG2 are associated with several epilepsy syndromes including childhood absence epilepsy, generalized tonic clonic seizures and the epileptic encephalopathy, Dravet syndrome. The molecular basis for the phenotypic heterogeneity of mutations is unclear. Here we focused on three nonsense mutations in GABRG2 (GABRG2(R136*), GABRG2(Q390*) and GABRG2(W429*)) associated with epilepsies of different severities...

OBJECTIVE: Acquired epilepsy is a devastating long-term risk of various brain insults, including trauma, stroke, infections, and status epilepticus (SE). There is no preventive treatment for patients at risk. Due to the complex alterations involved in epileptogenesis, it is likely that multi-targeted approaches are required for epilepsy prevention. We report novel preclinical findings with isoflurane, which exerts various non-anesthetic effects that may be relevant for anti-epileptogenesis...

To investigate whether seizure lateralization affects sleep macrostructure in patients with left and right temporal lobe epilepsy (TLE), as rapid eye movement (REM) sleep is shorter in patients with right hemispheric cerebral infarction than with left. We retrospectively analyzed data from 16 patients with TLE (6 men and 10 women aged 34.9 ± 11.4 years) who underwent polysomnography as well as long-term video electroencephalography. Ten patients were diagnosed with left TLE and six patients with right TLE...

Visibility graph has established itself as a powerful tool for analyzing time series. We in this paper develop a novel multiscale limited penetrable horizontal visibility graph (MLPHVG). We use nonlinear time series from two typical complex systems, i.e., EEG signals and two-phase flow signals, to demonstrate the effectiveness of our method. Combining MLPHVG and support vector machine, we detect epileptic seizures from the EEG signals recorded from healthy subjects and epilepsy patients and the classification accuracy is 100%...

OBJECTIVE: To ascertain efficacy and tolerability of carbamazepine (CBZ), sodium valproate (VPA), lamotrigine (LTG) and levetiracetam (LEV) using the UKAED register ( METHODS: Patients on CBZ (n=91), VPA (n=61), LTG (n=105), LEV (n=72) and healthy control subjects (CTR) on no medication (n=51) were extracted. All patients had anonymously provided information on seizure type and frequency and completed the Liverpool Adverse Event Profile (LAEP). RESULTS: The number of seizure-free patients in the last 4 weeks was overall CBZ/VPA/LTG/LEV=60%/79%/67%/67%, for generalized epilepsy was CBZ/VPA/LTG/LEV=67%/89%/65%/94%, and for localization-related epilepsy was CBZ/VPA/LTG/LEV=59%/71%/67%/57%...

PURPOSE: Three-tesla intraoperative MRI (iMRI) is a promising tool that could help confirm complete resections and disconnections in pediatric epilepsy surgery, leading to improved outcomes. However, a large proportion of epileptogenic pathologies in children are poorly defined on imaging, which brings into question the utility of iMRI for these cases. Our aim was to compare postoperative seizure outcomes between iMRI- and non-iMRI-based epilepsy surgeries. METHODS: We performed a comparative retrospective analysis of non-iMRI- versus iMRI-based epilepsy surgeries with 2-year follow-up...

PURPOSE: Levetiracetam (LEV) is often chosen early in the treatment of refractory epilepsy; however, its adverse effects have largely been studied as part of clinical trials. Oxcarbazepine and valproate (VPA) are the other commonly used AEDs and, hence, serve as good comparators. This study was conducted to evaluate behavioral abnormalities and somnolence among patients with epilepsy being treated with LEV and/or OXC compared with those receiving VPA. METHOD: Data of consecutive patients attending our intractable epilepsy clinic over a 2 1/2-year period were reviewed, and patients with at least one seizure a month, who had been initiated on either or a combination of LEV, VPA, or OXC, were included for analysis...

OBJECTIVE: Cognitive impairment is one of the major consequences of epilepsy and has been shown to reduce quality of life. Interictal epileptiform discharges (IEDs) were associated with poorer cognitive performance in children, and the aim of this study was to determine whether there was a similar association in adults. METHODS: A prospective cohort of 167 seizure-free adult patients underwent EEG recording and extensive cognitive evaluations. Global cognition was evaluated using Addenbrooke's Cognitive Examination-Revised (ACE-R), while sub-dimensions of cognition were evaluated using the Auditory Verbal Learning Test (AVLT), Trial Making Test (TMT)-A and -B, and the 5 constitutive subscales of ACE-R...

BACKGROUND: Perampanel, a new specific non-competitive AMPA receptor antagonist, has been recently approved in the United States and the European Union for the adjunctive treatment of focal seizures and primary generalized tonic-clonic seizures associated with idiopathic generalized epilepsy. A positive relationship between plasma perampanel concentration and improvement in seizure control has been identified in regulatory trials, suggesting that therapeutic drug monitoring (TDM) could be useful in optimizing clinical response in patients with epilepsy treated with perampanel...
