This report describes atypical absence seizures induced by phenobarbital (PB) in a patient with benign childhood epilepsy with centrotemporal spikes. An 11-year-old girl had nocturnal motor seizures, beginning at the age of 7 years. Interictal EEG displayed centrotemporal sharp waves in the left and right sides alternatively, which increased significantly(More)
Out of the 314 children with partial epilepsies below the age of 15 who had been followed for more than 5 years, 122 children with functional partial epilepsies (FPE) were the subjects of this study. The specific modality of interictal EEG findings reminiscent of that of the Rolandic spikes (Dalla Bernardina, 1982, 1984) was compared between functional and(More)
A retrospective study was carried out on 261 patients with various epilepsies who had undergone convulsive status epilepticus prior to the subsequent onset of epileptic seizures. 1. Convulsive status epilepticus was found more in partial epilepsy and secondary generalized epilepsy at about the same rate, and evidently less in primary generalized epilepsy.(More)
A prospective intraindividual study of WISC-R testing in the 45 children with epilepsy revealed that: 1) antiepileptic drugs, phenobarbital in particular, resulted in a detrimental effect on the WISC-R scores, 2) of the WISC-R subtests, vocabulary tasks of the verbal test were the most susceptible indicators in children whose FSIQ scores either improved or(More)
Previous reports concerning benign childhood epilepsy with centrotemporal spikes (BECT) were re-investigated, including new data concerning both the presentation of the long-term clinical courses of three cases and the results of magnetoencephalography (MEG) in one patient, with respect to the following points; (1) the electro-clinical characteristics of(More)
A longitudinal study was conducted in 89 children with partial seizures who had rolandic discharges on their interictal EEGs. The clinical characteristics and seizure prognosis were compared in children without an organic background (idiopathic) and in children with an organic background (symptomatic). Since rolandic discharges and sylvian seizures were(More)
We reported 3 cases with subacute sclerosing panencephalitis (SSPE) showing recurrent and involuntary motor phenomena. Their electroclinical correlates were analyzed using CCTV-EEG. Clinically, they slanted their trunks and/or heads, and dropped their upper limbs momentarily only when their antigravity muscles were suitably contracting (sitting, standing,(More)
1. The seizure manifestations of patients with hemiplegia were reminiscent of partial seizures. The motor manifestations were notably asymmetrical and impairment of consciousness was mild. Nevertheless, tonic seizures, identified by electroclinical correlation were found in 49 patients (88%) although they were predominantly unilateral or asymmetrical. 2.(More)
Two hundred and seventy eight absence seizures were recorded from 60 patients by an intensive monitoring device. They were divided into two subtypes, typical and atypical absences based on their ictal discharges whether the spike-wave rhythm was at 3 cps or not. These two absence seizures did not differ so much with regard to loss of consciousness except(More)
