Long-term video electroencephalography and clinical characteristics of 27 children with Rolandic discharge

Abstract

Objective To study and analyze the long-term video electroencephalography (VEEG) and clinical characteristics of children with Rolandic discharge.Methods Twenty-seven children with Rolandic discharge,admitted to our hospital from October 2009 to June 2013,were chosen in our study; theit clinical characteristics,VEEG results,imaging results,treatments and prognosis were retrospectively analyzed.Results In these 27 patients,19 had benign epilepsy with centrotemporal spikes (BECT),low-dose antiepileptic drug oxcarbazepine could obtain good efficacy in 15 patients and the other 4 did not give drug because of few seizures,and generally the prognosis was good; 2 had variants of BECT (therapy of antiepileptic drugs and corticosteroids had efficacy); 3 had symptomatic epilepsy (one was infantile autism,the other was encephalitis sequela,the last one was focal cortical dysplasia; therapy of antiepileptic drugs was combined,the result of the first one was good,the second one was not good,and the third was cured by surgery); and one had benign childhood occipital epilepsy and two had Tourette's syndrome.The VEEG of all 27 children showed numerous or single spikes on one side or both sides in Rolandic areas during wake-up and sleep; a few of them presented electrical status epilepticus during slow wave sleep.Conclusions Rolandic discharges in children are mostly seen in BECT,and secondly in symptomatic epilepsy and the variants of BECT,and sometimes in childhood occipital epilepsy and non-epilepsy children.VEEG monitoring can help the diagnosis and estimate the prognosis and instruct the therapy.
