The aim of this study was to determine the eff ect of 7-nitroindazole (7-NI – a preferential neuronal nitric oxide synthase inhibitor) on the protective action of oxcarbazepine (OXC) and vigabatrin (VGB) – two newer antiepileptic drugs (AEDs) against pentylenetetrazole (PTZ)-induced seizures in mice. The clonic seizure activity in mice was evoked by subcutaneous injection of PTZ (100 mg/kg) and...

Objectives: To study the anti-convulsant potential of leaves of Psidium guajava Linn. in MES and PTZ induced convulsion in experimental animals. Materials and methods: The anticonvulsant potential of the ethanolic extracts of Psidium guajava Linn. (EEPG) were tested in the mice model of Maximal electroshock (MES) and Pentylenetetrazole (PTZ). In the MES model, seizures were induced by deliverin...

Zinc homeostasis in the brain is associated with the etiology and manifestation of epileptic seizures. Adult Noda epileptic rats (NER, >12-week-old) exhibit spontaneously generalized tonic-clonic convulsion about once a day. To pursue the involvement of synaptic Zn(2+) signal in susceptibility to spontaneous seizures, in the present study, the effect of zinc chelators on epileptogenesis was exa...

OBJECTIVES We assessed the likelihood of 12-month seizure remission and treatment failure after failure of a first antiepileptic drug, and identified factors influencing these outcomes. METHODS SANAD (Standard and New Antiepileptic Drug) was a randomized controlled trial comparing monotherapy with standard and new antiepileptic drugs. Patients were followed up to study completion, even if the...

Creatine exerts beneficial effects on a variety of pathologies in which energy metabolism and oxidative stress play an etiological role. Creatine supplements have shown beneficial effects on neurological disorders including Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Alzheimer's disease and stroke. However, the potential benefits of creatine for patients with convu...

Seizures in the newborn period constitute a medical emergency. Subtle seizures are the commonest type of neonatal seizures, other types being clonic, tonic, and myoclonic. Myoclonic seizures carry the worst prognosis in terms of long-term neurodevelopmental outcome. Hypoxic-ischemic encephalopathy is the most common cause of neonatal seizures. Multiple etiologies often co-exist in neonates and ...

Epileptic seizures are characterized by periods of hypersynchronous, hyperexcitability within brain networks. Most seizures involve two stages: an initial tonic phase, followed by a longer clonic phase that is characterized by rhythmic bouts of synchronized network activity called afterdischarges (ADs). Here we investigate the cellular and network mechanisms underlying hippocampal ADs in an eff...

Phenytoin is indicated for the control of generalized tonic-clonic (grand mal) and complex partial (psychomotor, temporal lobe) seizures and prevention and treatment of seizures occurring during or following neurosurgery. Phenytoin has also been used in the treatment of migraine, trigeminal neuralgia and certain psychoses. It has also been used in cardiac arrhythmias, digitalis intoxications, a...

OBJECTIVE To investigate the sleep/wake, day/night, and 24-h periodicity of pediatric evolution to generalized tonic-clonic seizures (GTC). METHODS Charts of 407 consecutive patients aged 0-21 years undergoing continuous video-EEG monitoring for epilepsy were reviewed for the presence of GTC evolution. Seizures were characterized according to 2001 ILAE terminology. Charts were reviewed for EE...

The serum concentration of prolactin is frequently increased after single epileptic seizures and has therefore been used as a method to differentiate between hysterical attacks and epileptic seizures. We determined plasma prolactin concentrations in fifteen patients with status epilepticus. Seven patients had absence status, five complex partial and three generalised tonic-clonic status epilept...
