To investigate the effect of chronic VPA treatment of EEG functional connectivity in successfully treated idiopathic generalized epilepsy (IGE) patients.19-channel waking, resting-state EEG records of 26 IGE patients were analyzed before treatment (IGE) and after the 90th day of treatment (VPA), in seizure-free condition. Three minutes of artifact-free EEG background activity (without epileptiform...

Neurophysiology of juvenile myoclonic epilepsy: EEG-based network and graph analysis of the interictal and immediate preictal states

B. Clemens, S. Puskás, M. Besenyei, T. Spisák, more

Epilepsy Research > 2013 > 106 > 3 > 357-369

The neuronal mechanisms of enduring seizure propensity and seizure precipitation in juvenile myoclonic epilepsy (JME) are not known. We investigated these issues, within the framework of the “network concept” of epilepsy.Design1: 19, unmedicated JME patients were compared with nineteen, age-, and sex-matched normal control persons (NC). A total of 120s, artifact-free, paroxysm-free, eyes-closed, resting...

Remission of benign epilepsy with rolandic spikes: An EEG-based connectivity study at the onset of the disease and at remission

B. Clemens, S. Puskás, M. Besenyei, T. Spisák, more

Epilepsy Research > 2013 > 106 > 1-2 > 128-135

The neuronal mechanisms of remission of epilepsy are not known. Based on the principles of the “network theory of epilepsy” we postulated the existence of abnormal cortico-cortical interactions at the onset of epilepsy (Hypothesis-1), and postulated that remission is associated with the decrease or disappearance of the abnormal quantitative EEG findings (Hypothesis-2).Four children with benign epilepsy...

EEG-LORETA endophenotypes of the common idiopathic generalized epilepsy syndromes

B. Clemens, S. Puskás, M. Besenyei, M. Emri, more

Epilepsy Research > 2012 > 99 > 3 > 281-292

We tested the hypothesis that the cortical areas with abnormal local EEG synchronization are dissimilar in the three common idiopathic generalized epilepsy (IGE) phenotypes: IGE patients with absence seizures (ABS), juvenile myoclonic epilepsy (JME) and epilepsy with generalized tonic–clonic seizures exclusively (EGTCS).Groups of unmedicated ABS, JME and EGTCS patients were investigated. Waking EEG...

EEG background activity is abnormal in the temporal and inferior parietal cortex in benign rolandic epilepsy of childhood: A LORETA study

M. Besenyei, E. Varga, I. Fekete, S. Puskás, more

Epilepsy Research > 2012 > 98 > 1 > 44-49

Benign rolandic epilepsy of childhood (BERS) is an epilepsy syndrome with presumably genetic-developmental etiology. The pathological basis of this syndrome is completely unknown. We postulated that a developmental abnormality presumably results in abnormal EEG background activity findings.20 children with typical BERS and an age- and sex-matched group of healthy control children underwent EEG recording...
