Post-surgical Seizure Linked to Psychogenic Nonepileptic Seizures

Risk factors for PNES include low IQ and a history of psychiatric disorders


 

Patients who continue to have seizures after epilepsy surgery should be evaluated for psychogenic nonepileptic seizures (PNES), based on a recent retrospective analysis of 1,105 patients. Among this cohort, 697 patients experienced postoperative seizures, and 27 of the 697 had documented PNES, according to Ali A. Asadi-Pooya and associates. Risk factors associated with post–epilepsy surgery PNES included an intelligence quotient (IQ) below 80 and a history of a psychiatric diagnosis.
