Helen A2 - Arzimanoglou, Alexis PY - 2017 T2 - Pediatric Epilepsy 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 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/28 UR - neurology.mhmedical.com/content.aspx?aid=1138410509 ER -
