Paroxysmal events during prolonged video-video electroencephalography monitoring in refractory epilepsy.

Introduction: Given that epileptic seizures and non-epileptic paroxysmal events have similar clinical manifestations, using specific diagnostic methods is crucial, especially in patients with drug-resistant epilepsy. Prolonged video electroencephalography monitoring during epileptic seizures reveals epileptiform discharges and has become an essential procedure for epilepsy diagnosis. The main purpose of this study is to characterise paroxysmal events and compare patterns in patients with refractory epilepsy.

[Characteristics of patients with refractory epilepsy attended in a tertiary referral center in Costa Rica].
