Helen A2 Arzimanoglou, Alexis SR Print(0) ID 1138410509 T1 Episodic Events Mimicking Seizures in Childhood and Adolescence T2 Pediatric Epilepsy YR 2017 FD 2017 PB McGraw-Hill Education PP New York, NY SN 9780071496216 LK accesspediatrics.mhmedical.com/content.aspx?aid=1138410509 RD 2024/04/19 AB Epilepsy has often been described as the great imitator with protean paroxysmal manifestations from sudden arousals out of sleep, to confusional states, to stiffening only when the individual arises and turns to one side and not the other. However, each of the behaviors listed previously (and many, many others) can be equally well explained in many individuals by nonepileptic mechanisms. According to the International League Against Epilepsy, imitators of epileptic seizures are defined not by the presentation but by the absence of abnormal and excessive neuronal discharges. The International League Against Epilepsy (ILAE) subdivides nonepileptic events into physiological disturbances with a nonepileptic mechanism such as syncope, sleep disorders, paroxysmal movements, transient global amnesia, and migraine as well as nonepileptic events of psychogenic origin (which may occur in the same patient with documented epileptic seizures).1
