Electroencephalography after a single unprovoked seizure

Electroencephalography (EEG) remains an essential diagnostic tool in the evaluation of seizure disorders. The most recent clinical guidelines from the American Academy of Neurology for both children [1] and adults [2] recommend that an EEG be obtained after a single unprovoked seizure. Indeed, EEG abnormalities may be useful in identifying epileptogenic foci, structural abnormalities, and/or electrographic patterns associated with specific epilepsy syndromes. However, it is the potential predictive value of EEG that can have the most prominent role in the evaluation of a single unprovoked seizure.
