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 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 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)
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)
OBJECTIVE Genomic duplications that lead to autism and other human diseases are interesting pathological lesions since the underlying mechanism almost certainly involves dosage sensitive genes. We aim to understand a novel genomic disorder with profound phenotypic consequences, most notably global developmental delay, autism, psychosis, and anorexia(More)
As some apparently idiopatic epilepsies may occasionally pose diagnostic difficulties in regard to their precise status of etiology, evoked potentials, particularly visual evoked potential (VEP), may contribute to the diagnosis of childhood epilepsy with occipital paroxysms (CEOP) as a subsidiary method of evaluation. This study includes 19 children (10(More)
An etiologic evaluation of 86 patients with infantile spasms is presented and the place of cranial magnetic resonance imaging (MRI) findings within this spectrum is discussed. A total of 103 cranial MRIs, performed between 4 and 72 months of age, were analyzed and classified according to the etiologic and pathophysiologic aspects. Ninety-one percent of(More)
Subacute sclerosing panencephalitis is a progressive disorder which also presents with various types of seizures, mainly myoclonic jerks, atonic attacks and tonic-clonic seizures. We report two cases, documented by video-EEG that during the course of the disease also presented with tonic seizures. The differential diagnosis of non-epileptic paroxysmal(More)
PURPOSE To investigate the informative value of EEG and cranial magnetic resonance imaging (cMRI) in the prognosis of infantile spasms (ISs); 86 patients with ISs were included in this study. METHODS All cases had epileptic spasms, psychomotor retardation, and hypsarrhythmia in at least one of their EEGs. cMRIs and laboratory tests necessary for etiologic(More)
Autism may develop in children with West syndrome. This study was conducted to determine if EEG abnormalities in patients with West syndrome predict the later onset of autism. Two groups of patients with West syndrome, older than 6 years of age, were studied. One group consisted of those with a past history of West syndrome plus autism (N=14); the control(More)
