Epilepsy is among the most common disorders of the central nervous system and there is not an absolute method for its treatment. It has been shown that each seizure has a depressing effect on the following seizure. Thus, finding the mechanisms responsible in this phenomenon can improve our knowledge toward new ways for epilepsy treatment. In this study, the role of adenosine A1 receptors in ...

PURPOSE Controlled-release formulations of Valproate (VPA) reduce side effects by minimizing peak plasma VPA concentrations in patients with epilepsy. However, the impact of this on anti-seizure efficacy has not been thoroughly explored. Here the pharmacokinetics and pharmacodynamics of chronic intermittent (consequently, peak VPA concentrations) and continuous VPA administration were directly ...

Objective: Magnetic seizure therapy (MST) is under development as an alternative to electroconvulsive therapy (ECT), as it offers reduction in depression symptoms with fewer adverse cognitive effects. This study examined the feasibility and efficacy of MST versus ECT in a randomized trial of geriatric patients with severe depression, then compared the neurophysiological characteristics of seizu...

Aim To determine the precise effects of post-traumatic seizure activity on hippocampal processes, we induced seizures at various intervals after traumatic brain injury (TBI) and analyzed plasticity at CA1 Schaffer collateral synapses. Material and Methods Rats were initially separated into two groups; one exposed solely to fluid percussion injury (FPI) at 2 Psi and the other only receiving ka...

BACKGROUND Measures of EEG during ECT, for example, smaller post-seizure fractal dimension have predicted antidepressant response. The earlier study on this subject used bilateral ECT. This study aims to examine if this finding holds good even for unilateral ECT, using both fractal dimension and spectral power analysis of EEG. METHODS Fifty-one right-handed, drug-free patients with major depr...

OBJECTIVE Electrocorticography (ECoG) may be used to guide epilepsy surgery. However, anesthetics can suppress epileptiform activity or induce confounding burst-suppression patterns and the relationship between ECoG results and seizure outcome is controversial. In this study, we evaluated the ECoG activity under several different anesthetics and examined the relationship between ECoG and outcom...

Ictal bradycardia is rare and its localising value is debated. Bradyarrhythmias are, however, important because of their potential connection to sudden death and ability to affect clinical seizure manifestations. Cerebral hypoperfusion induces loss of consciousness, at times with myoclonic jerks, whose clinical differentiation from a generalised convulsive seizure may prove difficult. Two invas...

Background: Early recognition of neonatal seizures secondary to pathogenic variants in potassium or sodium channel coding genes is crucial, as these are often resistant commonly used anti-seizure medications, but respond well sodium-channel blockers. We report a unique aEEG pattern caused by SCN2A and KCNQ3 variants, adding regular EEG description. Methods: International multicentre descriptive...
