Description
Author: Gretchen Hinson, M.D. Educational Pearls: PNES vs. epilepsy: postictal state is diagnostic of an epileptic seizure (sonorous respirations and/or confusion, lasting typically 20-30 minutes); Epileptiform seizures show decrease in convulsion frequency, but increase in convulsion amplitude while PNES convulsions demonstrate episodic convulsion amplitudes; and epileptiform seizures usually do not pause. PNES is a form of conversion disorder and can be associated with underlying personality disorder; however there are patients with epilepsy that also can have PNES which complicates the diagnosis and treatment. Patients that are malingering may have flailing movements and might talk during the episodes - both not typical of epileptic seizures or PNES. Treatment for PNES is with psychotropic medications and psychotherapy as opposed to antiepileptic medications References: Avbersek, A; Sisodiya, S. (2010).
