Optimal duration for recording EEG in children and adolescents- a prospective interventional study

An EEG (electroencephalogram) is crucial for diagnosing, monitoring, and syndromic classification of epilepsy [1]. In individuals experiencing seizures, an epileptiform EEG displaying generalized spike and wave discharges predicts a five-year recurrence risk of 58%, compared to 26% for those with a non-epileptiform EEG [2]. A single 30-minute outpatient EEG reveals interictal epileptiform discharges (IEDs) in 29-56% of epilepsy patients, increasing to 82% with repeated EEGs [3 –5]. The cumulative yield after a second and third EEG following a first unprovoked seizure or newly diagnosed epilepsy is 40-70% [6].
