Epilepsy with continuous spikes and wave during slow sleep: A case report.

ABSTRACT

This report presents a 5.5-year-old girl who presented with multiple types of seizure disorder along with behavioral change, cognitive deterioration, and language impairment. Electroencephalography showed nearly continuous spike-wave during slow wave sleep. Both clinical and electrographic findings were consistent with epilepsy with continuous spikes and wave during slow sleep (CSWS). Although the seizures were well controlled with conventional antiepileptic drugs, improvement of behavioral, cognitive, and language functions was observed only after adding corticosteroid as an adjunctive treatment. Corticosteriod may have a role in treatment in children with CSWS.
