Thirty-one children divided into 3 groups were studied. Group I included 13 neurologically free children, aged 3-9 years and not receiving any medications. Group II consisted of 7 recently diagnosed non medicated epileptic children, aged 3.5-8 years. Eleven medicated epileptic children; aged 4-9 years represented group III. All children were examined thoroughly. EEG and brain CT scan were done ...

Most research on basic mechanisms of epilepsy and the design of new antiepileptic drugs has focused on synaptic transmission or action potential generation. However, a number of laboratory studies have suggested that nonsynaptic mechanisms, such as modulation of electric field interactions via the extracellular space (ECS), might also contribute to neuronal hypersynchrony and epileptogenicity. ...

This work reviews the current knowledge on epileptogenesis and pathophysiology of epilepsy. Recently, gene defects underlying four monogenic epilepsies (generalized epilepsy with febrile seizures, autosomal dominant nocturnal frontal lobe epilepsy, benign familial neonatal convulsions and episodic ataxia type 1 with partial seizures) have been identified, shedding new light on the pathophysiolo...

Epilepsy has 2-3% incidence worldwide. However, present antiepileptic drugs provide only partial control of seizures. Calcium ion accumulation in hippocampal neurons has long been known as a major contributor to the etiology of epilepsy. TRPV1 is a calcium-permeable channel and mediator of epilepsy in the hippocampus. TRPV1 is expressed in epileptic brain areas such as CA1 area and dentate gyru...

BACKGROUND One third of epileptic patients are resistant to several anti-epileptic drugs (AED). P-glycoprotein (P-gp) is an efflux transporter encoded by ATP-binding cassette subfamily B member 1 (ABCB1) gene that excludes drugs from the cells and plays a significant role in AEDs resistance. Over-expression of P-gp could be a result of polymorphisms in ABCB1 gene. We studied the association of ...

Dear editor, we read with interest the article by Gilio et al. (2008). Previous transcranial magnetic stimulation (TMS) studies in focal epileptic patients brought to controversial results. In one study, increased motor threshold (MT) was reported in cryptogenic partial epileptic patients and the results were considered to be related to antiepileptic drug treatment (Cincotta et al., 1998). In o...

OBJECTIVE There are some controversial studies on effects of anti-epileptic drugs (AEDs) on serum IgG subclasses; however, the role of these medications is still unclear. The aim of this study was evaluation the effects of anti-epileptic drugs on serum concentration of IgG and its subclasses METHODS Serum IgG and IgG subclasses of 61 newly diagnosed epileptic patients were measured at the beg...

OBJECTIVES Myoclonic epilepsy (ME) syndrome is not rare in north-eastern Europe; it is also seen in various forms. Familial occurrence of ME syndrome and acute intermittent porphyria (AIP) was observed in three siblings. The following report was aimed the differentiation between co-morbidity of two different disorders or presence the epileptic seizures within the clinical picture of latent AIP....

Cortical dysplasia (CD) is a neurodevelopmental disorder due to aberrant cell proliferation and differentiation. Advances in neuroimaging have proven effective in early identification of the more severe lesions and timely surgical removal to treat epilepsy. However, the exact mechanisms of epileptogenesis are not well understood. This review examines possible mechanisms based on anatomical and ...

BACKGROUND Epilepsy is a chronic disorder with unpredictably recurring seizure. Uncontrolled attacks can put patients at risk of suffering oro-facial trauma. Antiepileptic drugs (AED) provide satisfactory control of seizures in most of the patients with epilepsy. However use of AED has been found to cause many side effects inclusive of side effects in the oral cavity also. MATERIALS & METHODS...
