A spell in the epilepsy clinic and a history of "chronic pain" or "fibromyalgia" independently predict a diagnosis of psychogenic seizures

Abstract

The clinical suspicion for psychogenic nonepileptic seizures (PNES) is based on multiple features obtained in the history. We reviewed the records of all patients evaluated over 5 years in a single epilepsy clinic for refractory seizures who eventually underwent EEG/video monitoring. We designated two groups: (1) patients with a diagnosis of "fibromyalgia" or "chronic pain" and (2) patients who had a seizure during the visit, either in the waiting area or in the examining room. Of 36 patients with "fibromyalgia" or "chronic pain," 27 (75%) were found to have PNES. Of 13 patients who had a "seizure" during their clinic visit, 10 (75%) were found to have PNES. We conclude that each of these findings has a predictive value of 75%.
