In work the review of some clinik-morphological and pharmacological researches devoted to a temporal epilepsy and its experimental models is resulted. On the basis of the analysis of existing problems in working out antiepileptic drugs and in studying of mechanisms epilepsy necessity of development of new chronic experimental models of a temporal epilepsy is proved. The basic criteria of experimental model of a temporal epilepsy are generalised. It is shown that parametres of acute toxicity and the remote consequences of an intoxication convulsive agents from group GABA-receptor's chloride channel blockers correspond to the basic criteria a post-epistatus of model of a temporal epilepsy. The conclusion is presented on use possibility GABA-receptor's chloride channel blockers in quality agents for modelling of a temporal epilepsy.

Our previous in silico data indicated an overrepresentation of the ZF5 motif in the promoters of genes in which circadian oscillations are altered in the ventral hippocampus in the pilocarpine model of temporal lobe epilepsy in mice. In this study, we test the hypothesis that the Zbtb14 protein oscillates in the hippocampus in a diurnal manner and that this oscillation is disrupted by epilepsy. We found that Zbtb14 immunostaining is present in the cytoplasm and cell nuclei.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis.

Mutations to the gene encoding NHE6 are responsible for CS, and we recently demonstrated that a mutation to the rat gene causes a similar phenotype in the spontaneous rat model, which exhibits cerebellar degeneration with motor dysfunction. In previous work, we used the PhP.
View Article and Find Full Text PDFTemporal lobe epilepsy with hippocampal sclerosis (TLE-HS) is associated with a complex genetic architecture, but the translation from genetic risk factors to brain vulnerability remains unclear. Here, we examined associations between epilepsy-related polygenic risk scores for HS (PRS-HS) and brain structure in a large sample of neurotypical children, and correlated these signatures with case-control findings in in multicentric cohorts of patients with TLE-HS. Imaging-genetic analyses revealed PRS-related cortical thinning in temporo-parietal and fronto-central regions, strongly anchored to distinct functional and structural network epicentres.

Objective: To observe and measure the morphological and temporal evolutionary features of the hypersynchronous (HYP) pattern in the mesial temporal seizure.
Methods: The HYP patterns during preictal and interictal states of 16 mesial temporal epileptic patients were analyzed. The wave components of the HYP transients were firstly observed and measured.
