The Use of EEG in the Diagnosis of Childhood Epilepsy

Abstract

This chapter presents an evidence-based approach for the necessity of using electroencephalography (EEG) or the lack thereof, in identifying a seizure, risk of epilepsy, and identifying epilepsy syndromes. The EEG has many limitations, but remains the gold standard for determining seizure risk and type and identifying epilepsy syndromes. It may prognosticate and determine the urgency and type of seizure management required. History and exam should determine when it is necessary, should assist in its interpretation and it should be interpreted by an expert in the field. It still also has utility in directing investigative flow as to when newer genetic and neuroimaging studies are warranted for diagnostic confirmation. The EEG also has uses outside of diagnosing seizures and epilepsy syndromes such as quantifying cerebral dysfunction and defining prognosis. © 2013 John Wiley & Sons, Ltd.
