Background and Objective: Chronic arsenic toxicity is a widespread problem; the role of brain oxidative stress has been suggested in the genesis of epilepsy and in the post-seizure neuronal death. However, studies investigating the effects of arsenic on seizure and related mechanisms are limited. The purpose of this study was to examine the effect of prolonged exposure to sodium arsenite on oxi...

temporal lobe epilepsy (tle) is a disorder of the central nervous system in which hippocampus is mostly involved and causes memory impairment. kindling is a model of inducing epilepsy which is created through pentylenetetrazol (ptz) administration. this study examines the role of the aqueous extract of boswellia on the learning and development of brain (formation of dendritic branches and axons...

Introduction: Olive leaf contains anti-inflammatory and COX-2 inhibitor compounds. Considering the role of the COX enzyme in seizures, this research was performed to assess the effects of this extract in treatment of seizures induced by PTZ. Methods: In this research, male Wistar rats (200±20 g) were injected intra-cerebroventricularly with 1 μl saline or olive leaf extract (125 μg, 250 μg ...

Background: Seizure is due to the abnormal electric activity of neurons in the brain. Because of the side effects of synthetic drugs, plant medicines can be used instead to control seizures.  Objectives: This study aimed to investigate the effect of aerobic exercise and α-pinene on pentylenetetrazole-induced seizures in mature male rats. Materials & Methods: A total of 40 Wistar male rats (we...

Introduction: Recently, herbal medicine is widely used as an alternative and complementary therapy in several neurological disorders such as epilepsy. The anti-inflammatory and neuroprotective effects of Zingiber officinale or ginger have been well-documented. The present study was designed to evaluate the effects of ginger extract pre-treatment on seizures behavior, neuronal density and as...

Seizures may cause brain injury via a variety of mechanisms, potentially contributing to cognitive deficits in epilepsy patients. Although seizures induce neuronal death in some situations, they may also have "nonlethal" pathophysiological effects on neuronal structure and function, such as modifying dendritic morphology. Previous studies involving conventional fixed tissue analysis have demons...

Activation of specific cortical territories by sensory stimuli or of less restricted areas of the brain by cognitive stimuli is known to induce apparently generalized seizures in predisposed patients; this is clinically and electroencephalographically distinct from reflex triggering of partial seizures. Photosensitive patients may have seizures when exposed to environmental stimuli producing ap...

When computed tomography started to be used routinely in the evaluation of patients presenting with seizures it became evident that some periictal abnormalities disappeared in follow-up studies with no specific treatment except antiepileptics. These findings suggested that those reversible abnormalities were not structural but functional, possibly resulting from the cerebral edema induced by se...

Startle-induced seizures are reflex seizures precipitated by a sudden, surprising stimulus, usually auditory. Aetiologies, electroencephalographic correlates, and brain structural abnormalities are variable. Because of the frequent tonic component at onset, falling is a major clinical problem. There is no established drug of choice, and therapy is often unsatisfactory. Adjunctive lamotrigine th...
