“…Video-EEG has been in use for the past two to three decades in LA. Even though vEEG availability is limited in LA, it is nevertheless used, where available, to diagnose PNES [10,13,14,25,[28][29][30][31][32] and often recommended to be used whenever possible to avoid misdiagnosing patients. Even when vEEG is not available, patients with seizures will still be seen by neurologists and epileptologists.…”

“…Reviewing existing literature in LA reveals that a few studies focused on the prevalence of ES in patients diagnosed with PNES [10,11,26], and some have reviewed retrospective data for PNES identification purposes [13,27]. Stressing the treatment gap for PNES, literature in LA, largely from Argentina and Brazil, reveals that vEEG usage is highly suggested as a diagnostic tool (where available) to correctly diagnose the patients [10,[13][14][15]25,26,[28][29][30][31][32][33][34]. Studies in LA have identified higher frequencies of psychiatric comorbid diagnoses, such as anxiety and dissociation, than studies in the US [11,15,25,27,35,36].…”

“…Outpatient short‐duration video‐EEG has been increasingly used in recent years as a means to enhance the diagnostic yield of EEG, particularly to confirm or rule out an epileptic origin of paroxysmal events. This technique also allows better characterization and recognition of subtle seizures in known epilepsy patients (4–10). Although several studies on outpatient short‐duration video EEG have been reported in recent years, the duration of the EEG recordings has ranged from 2 h (5,10) to an average of 8 h (4).…”

“…Main indications for this procedure include the diagnosis of epilepsy and seizure classification, the differentiation between epileptic and nonepileptic events, the characterization of seizure frequency, and presurgical evaluation (2,3). Despite its advantages, the procedure has significant limitations, which include the high cost associated with hospital admission, the discomfort to the child and his family, and the need for highly trained staff to handle the equipment during the long procedure (4,5).…”

Summary:Purpose: To report on the usefulness of adding video recording to routine EEG studies of infants and children with frequent paroxysmal events.Methods: We analyzed the efficacy of this diagnostic means during a 4-year period. The decision whether to add video recording was made by the pediatric EEG interpreter at the time of the study. Studies were planned to last between 20 and 30 min, and, if needed, were extended by the EEG interpreter. For most studies, video recording was added from the beginning of EEG recording. In a minority of cases, the addition of video was implemented during the first part of the EEG test, as clinical events became obvious. In these cases, a new study (file) was begun. The success rate was analyzed according to the indications for the EEG study: paroxysmal eye movements, tremor, suspected seizures, myoclonus, staring episodes, suspected stereotypias and tics, absence epilepsy follow-up, cyanotic episodes, and suspected psychogenic nonepileptic events.Results: Video recording was added to 137 of 666 routine studies. Mean patient age was 4.8 years. The nature of the event was determined in 61 (45%) of the EEG studies. Twenty-eight percent were hospitalized patients. The average study duration was 26 min. This diagnostic means was particularly useful for paroxysmal eye movements, staring spells, myoclonic jerks, stereotypias, and psychogenic nonepileptic events. About 46% of 116 patients for whom cognitive data were available were mentally retarded. EEG with added video recording was successfully performed in all 116 cases and provided useful information in 29 (55%) of these 53 patients.Conclusions: Adding video recording to routine EEG was helpful in 45% of cases referred for frequent paroxysmal events. This technique proved useful for hospitalized children as well as for outpatients. Moreover, it was successfully applied in cognitively impaired patients. Infants and children with paroxysmal eye movements, staring spells, myoclonic jerks, stereotypias, and pseudoseizures especially benefited from this diagnostic means. Because of its low cost and the little discomfort imposed on the patient and his or her family, this technique should be considered as a first diagnostic step in children with frequent paroxysmal events. Key Words: Video recording-Routine-Electro encephalogram-Children.Prolonged video-EEG has long been used in the evaluation of paroxysmal events in children (1,2). With this diagnostic means, a correlation between clinical events suggestive of being epileptic seizures and EEG activity can be established in many cases, thus confirming or ruling out the epileptic nature of these events.Main indications for this procedure include the diagnosis of epilepsy and seizure classification, the differentiation between epileptic and nonepileptic events, the characterization of seizure frequency, and presurgical evaluation (2,3). Despite its advantages, the procedure has significant limitations, which include the high cost associated
