gamma-aminobutyric acid (gaba) is an important inhibitory transmitter in central nervous system and is involved in pathophysiology of epilepsy. pentylenete-trazole (ptz), a convulsant agent, partly acts via anion channel of gabaa receptor. ivermectin, an antiparasitic agent and a gabaa agonist, has anticonvulsant effect in animal seizure models. cholestasis increases the threshold of ptz-induce...

When studying the role of the locus coeruleus (LC) in the regulation of seizure susceptibility in rats, we found that bilateral LC lesion significantly lowered the electroshock seizure threshold for the tonic extension of forelegs. The pattern of maximal electroshock seizure was not affected by LC lesion, although the recovery time was slightly prolonged. In the pentylenetetrazol (PTZ) seizure ...

The International League Against Epilepsy (ILAE) presents a revised operational classification of seizure types. The purpose of such a revision is to recognize that some seizure types can have either a focal or generalized onset, to allow classification when the onset is unobserved, to include some missing seizure types, and to adopt more transparent names. Because current knowledge is insuffic...

Introduction: There is evidence that diabetes affects seizure susceptibility. Ginger (Zingiber officinale Roscoe) which is used in traditional medicine has antioxidant activity and neuroprotective effects. The aim of this study was to evaluate the seizure threshold induced by pentylenetetrazole (PTZ) in diabetic mice after induction of diabetes with streptozocin and to examine the possible ...

We describe a case of a 50-year-old Hispanic man diagnosed with HIV/AIDS who presented with a generalized tonic clonic seizure and ring enhancing cerebral lesions on imaging. He was initially treated for CNS toxoplasmosis but presented to the hospital with another tonic clonic seizure despite prescribed therapy. Brain biopsy was performed which revealed Nocardia beijingensis. He was treated wit...

In this report a 20-year-old male patient who had suffered tonic-clonic seizure after a single induction dose of etomidate until a bispectral index value of 60 is presented. Our best knowledge, this case is the first report of pure etomidate (with induction dose) induced generalized tonic clonic seizure proven with EEG. Anaesthesiologists should be careful against such a complication even in th...

In the PTZ animal model of epilepsy, electrical stimulation applied to the amygdaloid complex may result in either pro-convulsive or anticonvulsant effect, depending on the temporal pattern used (i.e. periodic-PS and non-periodic-NPS electrical stimulation). Our hypothesis is that the anatomical target is a determinant factor for the differential effect of temporally-coded patterns on seizure o...
