The aim of this paper is to promote the correct classification of, and provide guidelines on, the diagnosis and management of Panayiotopoulos syndrome (PS). An international consortium of established researchers in the field collaborated to produce a consensus document. The resulting document defines PS, characterizes its electro-clinical features,(More)
PURPOSE Despite the benign prognoses of idiopathic partial epilepsies, particularly regarding the response of seizures to treatment, some evidence now exists that patients with such disorders may have subtle neuropsychological deficits. This study was designed to investigate several modalities of neuropsychological functioning in a group of 21 patients,(More)
PURPOSE Questioning the presence of any possible prognostic predictors, this study includes a long-term follow-up of clinical and EEG characteristics of 16 patients with idiopathic partial epilepsy (IPE) who subsequently developed epilepsy with electrical status epilepticus during slow sleep (ESES) spectrum disorders. METHODS Epilepsy, cognitive and(More)
PURPOSE Our aim is to outline the clinical and electroencephalographic (EEG) features of patients with hot water epilepsy (HWE), a rare and unique form of reflex epilepsy. METHODS Twenty-one patients with HWE, seen in our clinic until 1999, were studied. Male outnumbered female subjects in a ratio of 3:1. The age at the onset of seizures ranged from 19(More)
OBJECTIVE Succinic semialdehyde dehydrogenase (SSADH) deficiency is a neurometabolic disorder characterized by excessive GABA levels and seizures. There has been no clinical phenotype described to date with heterozygosity for SSADH deficiency. METHODS A patient heterozygous for SSADH deficiency presented with absence and myoclonic seizures. EEG monitoring(More)
PURPOSE The typical clinical presentation of subacute sclerosing panencephalitis (SSPE) includes behavioral and intellectual changes followed by myoclonia. However, there are a considerable number of SSPE cases which present with distinct clinical features that can lead to a diagnostic difficulty. In this report, we summarize the clinical features of(More)
This study was performed to investigate some clinical parameters of febrile seizures (FSs) in patients with epilepsy, testing any possible correlation between those parameters and the type of subsequent epilepsy. One hundred and nine patients with epilepsy having a history of FSs were evaluated for age at onset of FSs, interval between first FS and first(More)
Although the seizure prognosis is mostly favorable in idiopathic partial epilepsies, there is some empirical evidence showing that subtle neuropsychological impairments, with a consequent risk of academic underachievement, are not rare. We investigated neuropsychological functioning including attention, memory, visuomotor ability, and executive functioning(More)
The purpose of this study was to investigate the informative value of single photon emission tomography (SPECT) in relation to the pathophysiological functioning of the brain during absence seizures and the origin of ictal discharges in idiopathic generalized epilepsies (IGEs). Six patients with childhood absence epilepsy (CAE) were selected for the study(More)
The aim of this study was to demonstrate the effect of administration of gamma-aminobutyric acid (GABA)(A) receptor antagonist, bicuculline, into the reticular nucleus of the thalamus (nRt) on spike and wave discharges (SWD) and cardiovascular regulation in conscious rats with genetic absence epilepsy. Rats were instrumented with guide cannulas for drug(More)
