Behavioral Disorder non-epileptic seizure true Non-epileptic seizures (previously known as non-epileptic attacks, psychogenic seizures and pseudoseizures) resemble epileptic seizures, but have no electrophysiological correlate or clinical evidence for epilepsy. The etiology of non-epileptic seizures is heterogeneous, with different predisposing, precipitating and promoting factors in different affected individuals. Psychogenic factors may promote the emergence of non-epileptic seizures, but psychogenic factors may not be able to be identified in all cases. The seizure-like event may include movement or impaired awareness, and can imitate focal motor seizures or focal impaired awareness seizures. Motor features that distinguish these attacks from seizures include a prominence of proximal or truncal movements, waxing and waning pattern of movements, variable rate and direction of jerking, horizontal movements of the head, crying during or after the event, and eye closure with resistance to passive eye opening. Diagnosing non-epileptic seizures is important because of the potential serious side effects of anti-seizure medications and associated procedures for treating epilepsy such as intubation and ventilation. The failure to recognize the psychological factors contributing to these events also delays implementation of appropriate psychological treatment. Video EEG monitoring and concomitant psychological evaluation is typically required to establish the diagnosis and the treatment plan.
