Background: Non-Epileptic Paroxysmal Events (NEPE) are common clinical manifestations in pediatric age presenting with dysfunction of motor and behavioral activity mimicking features of epileptic seizures. Objective: To present and analyze number and clinical characteristic of a group of children/adolescents presenting with various types of NEPE; to compare clinical data of this group of NEPE affected children/adolescents with a group of children/adolescents affected by Epileptic Seizures (ES). Methods: The retrospective study was conducted at the Pediatric Clinic of University of Catania, Catania, Italy, in a period ranging from January 2005 and January 2018. Two groups of children/adolescents, aged from 1 month to 15 years, were selected: 312 affected by NEPE and 192 by ES. Number and percentage of the single type of NEPE were reported. Then, demographic characteristics, clinical manifestations, duration of the events, time of diagnosis, and age of onset of each type of NEPE and ES affected children/adolescents were analyzed and compared. Results of statistical analysis of the data were carried out between ES and some type of NEPEs including Sandifer syndrome, breath-holding spells, paroxysmal tremors, vertigo, and syncope. Results: Among the group of NEPE, vertigo, type of paroxysmal event clinically not classifiable, syncope, and Sandifer syndrome were the most common events; In the comparative analyzed samples, variability between NEPE and ES was found in the duration of the paroxysmal events, in number of episodes, in lag-time between the onset of symptoms and the diagnosis, and in age of onset. Analyzing clinical data of ES with some type of NEPE, statistical significant results were obtained in vertigo as regards the duration and average duration event, in paroxysmal tremors as number of events, in Sandifer syndrome as lag-time of diagnosis, and finally in all the types of NEPE as regards the age of onset, and loss of consciousness. Conclusions: Analyzing the clinical features of each type of NEPE differences with ES are found. However, globally considered diagnostic differences between NEPE and ES remain difficult, questionable, and unrealizable without the support of correct parental report, direct clinical observations, and video-EEG monitoring.

Abstract

Background: Non-Epileptic Paroxysmal Events (NEPE) are common clinical manifestations in pediatric age presenting with dysfunction of motor and behavioral activity mimicking features of epileptic seizures. Objective: To present and analyze number and clinical characteristic of a group of children/adolescents presenting with various types of NEPE; to compare clinical data of this group of NEPE affected children/adolescents with a group of children/adolescents affected by Epileptic Seizures (ES). Methods: The retrospective study was conducted at the Pediatric Clinic of University of Catania, Catania, Italy, in a period ranging from January 2005 and January 2018. Two groups of children/adolescents, aged from 1 month to 15 years, were selected: 312 affected by NEPE and 192 by ES. Number and percentage of the single type of NEPE were reported. Then, demographic characteristics, clinical manifestations, duration of the events, time of diagnosis, and age of onset of each type of NEPE and ES affected children/adolescents were analyzed and compared. Results of statistical analysis of the data were carried out between ES and some type of NEPEs including Sandifer syndrome, breath-holding spells, paroxysmal tremors, vertigo, and syncope. Results: Among the group of NEPE, vertigo, type of paroxysmal event clinically not classifiable, syncope, and Sandifer syndrome were the most common events; In the comparative analyzed samples, variability between NEPE and ES was found in the duration of the paroxysmal events, in number of episodes, in lag-time between the onset of symptoms and the diagnosis, and in age of onset. Analyzing clinical data of ES with some type of NEPE, statistical significant results were obtained in vertigo as regards the duration and average duration event, in paroxysmal tremors as number of events, in Sandifer syndrome as lag-time of diagnosis, and finally in all the types of NEPE as regards the age of onset, and loss of consciousness. Conclusions: Analyzing the clinical features of each type of NEPE differences with ES are found. However, globally considered diagnostic differences between NEPE and ES remain difficult, questionable, and unrealizable without the support of correct parental report, direct clinical observations, and video-EEG monitoring.
