Perampanel is an approved adjunctive treatment for focal seizures with or without focal to bilateral tonic-clonic (FBTC) seizures and generalized tonic-clonic (GTC) seizures. We compared efficacy and safety of perampanel vs placebo in Asian and non-Asian populations in a post hoc analysis of pooled
T-type (Cav3) calcium channels play important roles in neuronal excitability, both in normal and pathological activities of the brain. In particular, they contribute to hyper-excitability disorders such as epilepsy. Here we have characterized the anticonvulsant properties of TTA-A2, a selective
The spontaneously epileptic rat (SER: tm/tm, zi/zi) shows both absence-like seizures and tonic convulsions. Our previous studies have demonstrated that absence-like seizures of the tremor rat (tm/tm), one of the parent strains of SER, were inhibited by adenoviral transfer of the aspartoacylase
The effects of benzodiazepines (BDZs) and GABA system on tonic and clonic component of postdecapitation convulsion (PDC) were studied in mice. Mice decapitated at the occipito-cervical junction, exerted biphasic convulsions, i.e., initially tonic and subsequently clonic convulsions. BDZs such as
The aim of this study was to evaluate the efficacy of conventional antiepileptic drugs (AEDs) against the generalized tonic-clonic seizures in mice subjected to the subconvulsive doses of N-methyl-D-aspartate (NMDA) or kainate.
Mice were given NMDA and kainate in the doses of 50.0
Previous neuroimaging studies of epilepsy with generalized tonic-clonic seizures (GTCS) focus mainly on adults. However, the neural mechanisms that underline this type of epilepsy remain unclear, especially for children. The aim of the present study was to detect the effect of epilepsy on brains of
To assess the effects of valproate (VPA) on seizure response/control and photosensitivity (PS) in adolescents suffering from photosensitive epilepsy with generalized tonic-clonic seizures only (EGTCS).
We prospectively evaluated 55 adolescents with newly diagnosed EGTCS and PS at
Prothrombotic conditions are known risk factors for porencephalic cyst formation and cerebral vein thrombosis. Intracerebral hemorrhage is a potential complication of a cerebral vein thrombosis. Porencephaly is a risk factor for intracerebral hemorrhage and cerebral vein thrombosis formation. We
It is widely agreed that after two or more seizures patients should be given antiepileptic treatment, but there is still controversy about the treatment of patients after a first unprovoked seizure. In a multicenter, randomized, open trial, patients with a first tonic-clonic seizure were randomized
A precondition for the diagnosis of primarily generalized epilepsy with tonic-clonic seizures (GTCS) is absence of brain pathology. This definition, based on normal findings on computed tomography (CT) and magnetic resonance imaging (MRI) is challenged however, by observation of
The action of MK-801 (NMDA antagonist; 0.1 and 0.5 mg/kg, IP) was tested against picrotoxin-induced seizures (3-6 mg/kg, IP) in rats aged 7, 12, 18, 25, and 90 days. We found MK-801 only inconsistently affected clonic seizures in 12- and 25-day-old rats, whereas tonic-clonic seizures were suppressed
To determine incidence and early predictors of generalized tonic-clonic seizures (GTCs) in children with childhood absence epilepsy (CAE).
Occurrence of GTCs was determined in 446 children with CAE who participated in a randomized clinical trial comparing ethosuximide, lamotrigine,
The analysis of generalized tonic clonic seizures is usually difficult with scalp EEG due to muscle artifact. We applied Gabor Transform to evaluate 20 seizures from 8 consecutive patients admitted for video-EEG monitoring. We studied the relative intensity ratios of alpha, theta and delta bands
This study records noise-free intracerebral EEG of the genetically epilepsy prone rat (GEPR-9), along with behavioral correlates, during a seizure on unanesthetized freely behaving unrestrained animals. The GEPR-9 exhibits acoustically triggered generalized tonic-clonic seizures, and often times the
We performed a multicenter case-control study to estimate whether chronic alcoholism and alcohol consumption are risk factors for developing a first generalized tonic-clonic seizure (GTCS). We studied 237 first-seizure patients (158 men, 79 women) matched to 474 hospital controls for center, sex,
