ischemia/seizures

Acute "silent" seizures after brain injury are associated with a worsening of patient outcome and are often refractory to anti-epileptic drug (AED) therapy. In the present study we evaluated topiramate (TPM, 1-30 mg/kg, i.v.) in a rodent model of spontaneous non-convulsive seizure (NCS) activity

Transient cardiac arrest due to cardiac vessel bundle occlusion was used to produce a rat model of spontaneous and audiogenic seizures. Among the rats, spontaneous seizures were present in 64%, and audiogenic seizures could be evoked in 86%, during two weeks of survival after cardiac arrest, by

OBJECTIVE To determine the extent to which neonatal seizures are associated with intrapartum hypoxia-ischemia. METHODS In this case-control study, all neonates diagnosed with seizures at a single institution from 1988 to 1999 were compared to a control group without seizures matched in a 2:1 fashion

The goal of this study was to develop a new model of ischemia-induced seizures in immature rats using injection of vasoconstrictor Endothelin-1 (ET-1) into the brain. ET-1 (10, 20, or 40 pmol) was infused into the left dorsal hippocampus of freely moving Wistar rats 12 (P12) and 25 (P25) days old.

BACKGROUND The aim of this investigation was to verify whether brain hypoxia represented a risk factor for the occurrence and severity of opioid abstinence syndrome. METHODS Three newborns who manifested seizure activity as a result of hypoxia, focal brain ischemia, and hypoxia and sepsis,

Unilateral carotid ligation in immature rats, followed by 2 h of hypoxia led to ischemic cell change from 2 h after the insult, on the ligated side of the brain. There was a time-dependent induction of immunoreactive c-fos protein in neurones but not glia or ependyma on the non-ligated side of the

Eclampsia is diagnosed in preeclamptic patients who develop unexplained seizures and/or coma during pregnancy or postpartum. Eclampsia is one of the leading causes of maternal and infant morbidity and mortality, accounting for ~13% of maternal deaths worldwide. Little is known about the mechanisms

Patients surviving ischemic stroke often express delayed epileptic syndromes. Late poststroke seizures occur after a latency period lasting from several months to years after the insult. These seizures might result from ischemia-induced neuronal death and associated morphological and physiological

EEG was continuously recorded from Mongolian gerbils for 4 days after transient bilateral forebrain ischemia, to determine whether ischemic brain damage in this species is necessarily associated with seizures. Gerbils were chronically implanted with EEG recording electrodes in hippocampal area CA1,

BACKGROUND Experimental data provide evidence on the induction of a susceptibility to audiogenic seizures in rats surviving cardiac arrest and subsequent global brain ischemia. The aim of this study was to find out whether cardiac arrest in rats could affect seizure susceptibility in the long-term

This study evaluates the neuroprotective properties of some voltage-sensitive sodium channel blockers in a model of focal ischaemia. After curative treatment (0.5 and 24.5 h after insult), well known voltage-sensitive sodium channel blockers, phenytoin (2 x 100 mg/kg i.p.), carbamazepine (2 x 50

Transient global ischemia was used to produce a rat model of generalized tonic-clonic epilepsy. Controlled chest compression in ketamine-anesthesized Long-Evans rats produced transient global ischemia by mechanically preventing the heart from pumping blood. Circulation was restored by standard

Stroke is a leading cause of death, disability, and socioeconomic loss worldwide. All attempts at pharmacological reduction of the complications of stroke (e.g. post-stroke seizure, and brain׳s vulnerability to hypoxic/ischemic injury) have failed. Endogenous opioids and nitric oxide (NO)

We describe the clinical course of a young female Caucasian patient with bilateral moyamoya disease in whom we could diagnose the simultaneous occurrence of cerebral ischemia, TIAs, limb shaking TIAs and focal Jacksonian seizures. It is the second clinical communication in the literature elaborating

Epileptiform EEG activity associated with ischemia can contribute to early damage of hippocampal neurons, and seizure activity may also lead to dysfunction in extrahippocampal regions. In this study, seizure activity associated with the four-vessel occlusion model of cerebral ischemia was monitored
