title: Effect of corticosteroids in a twin child with idiopathic localization-related epilepsy.
abstract: Corticosteroids have been used only in the treatment of special epileptic syndromes or epileptic encephalopathies, such as infantile spasms. We report an antiepileptic effect of corticosteroids that were used for treatment of nephropathy in a monozygotic twin child with idiopathic localization-related epilepsy (I-LRE). The patient and her monozygotic twin sister exhibited repeated partial seizures at two years of age and electroencephalogram (EEG) showed focal spikes in the occipital area and, on other occasions, the centro-parietal areas. After oral antiepileptic drugs were started, the twins still exhibited occasional seizures. The patient had IgA nephropathy at four years of age and intravenous methylprednisolone and oral prednisolone were administered. Her seizures and epileptiform discharges on EEG disappeared, while her sister continued to have seizures and EEG abnormalities. When the dose of oral predonisone was reduced, the seizures relapsed and EEG again revealed focal spikes. We conclude that corticosteroids exhibit efficacy towards seizures and epileptiform discharges on EEG in patients with I-LRE without epileptic encephalopathies.
