PURPOSE The aim of our study was to test the efficacy of the VARIA system (video, accelerometry, and radar-induced activity recording) and validation of accelerometry-based detection algorithms for nocturnal tonic-clonic and clonic seizures developed by our team. METHODS We present the results of two patients with tonic-clonic and clonic seizures, measured for about one month in a home enviro...

The mechanisms underlying electrophysiologically observed two-way transitions between absence and tonic-clonic epileptic seizures in cerebral cortex remain unknown. The interplay within thalamocortical network is believed to give rise to these epileptic multiple modes of activity and transitions between them. In particular, it is thought that in some areas of cortex there exists feedforward inh...

Serum phenytoin concentrations were monitored prospectively in 26 patients with previously untreated partial epilepsy, during monotherapy with phenytoin. Only six remained entirely seizure-free, although only four experienced further tonic-clonic seizures. There was no correlation between serum phenytoin concentrations and freedom from partial seizures in those patients in whom such seizures re...

Oxaliplatin is a common chemotherapy drug used for colon and gastric cancers. Common side effects are peripheral neuropathy, hematological toxicity, and allergic reactions. A rare side effect is seizures which are usually associated with posterior reversible leukoencephalopathy syndrome (PRES). A 50-year-old male patient presented with severe abdominal pain. CT scan of the abdomen showed acute ...

We have previously reported increased concentrations of interleukin (1L)-6 in CSF from patients with tonic-clonic seizures, where increased cytokine production most likely is a consequence of neuronal epileptic activity associated with seizures. The biological effects of IL-6 are mediated by other cytokines, which are studied here in addition to IL-6. The purpose of this study was to analyze le...

Seizures remain uncontrolled in 30% of patients with epilepsy, even with concurrent use of multiple drugs, and uncontrolled seizures result in increased morbidity and mortality. An extreme example is Dravet syndrome (DS), an infantile-onset severe epilepsy caused by heterozygous loss of function mutations in SCN1A, the gene encoding the brain type-I voltage-gated sodium channel NaV1.1. Studies ...

Neurological effects of Valeriana officinalis have been recognized for many years. In this study, the anticonvulsant activity of methanolic extract of the plant were investigated in mice. Picrotoxin with doses of 6 and 12.5 mg/kg were used for induction of seizures. The effects of different doses of methanolic extract of the plant on the variation of beginning time of seizures, the incidence of...

Case presentation: Male, 9 years old, healthy, after a dental procedure, he started with clonic seizures on the left side and an episode of tonic-clonic seizure. In evolution patient developed Epilepsia Partialis Continua (EPC) at side. Liquor investigation was positive to herpes virus despite acyclovir treatment for 21 days persisted seizures. Resonance image demonstrated atrophic lesion front...

Dravet syndrome (DS) is one of the refractory epileptic encephalopathies [3], one of the spectra of severe myoclonic Epilepsy of Infancy (SMEI) which occurs in otherwise healthy individuals [2]. Its incidence has been estimated to be 1 in 2000040000. It is more common in males than in females. Positive family history is encountered in one fourth of the cases. DS Usually started by clonic/tonic-...

A series of 140 previously untreated patients with tonic-clonic or partial seizures were randomised to receive either phenytoin or sodium valproate. There was no difference between the treatment groups in pretreatment variables that might influence outcome. Sodium valproate and phenytoin in the treatment of tonic-clonic or partial seizures showed no difference in efficacy as regards time to two...
