Brief Communications

How many patients with psychogenic nonepileptic seizures also have epilepsy?

From the Department of Neurology, Comprehensive Epilepsy Program, University of South Florida College of Medicine (Drs. Benbadis, Agrawal, and Tatum), Tampa General Healthcare (Drs. Benbadis and Tatum), and The James A. Haley Veterans Administration Hospital (Dr. Benbadis), Tampa, FL.

The proportion of patients with psychogenic nonepileptic seizures (PNES) who also have epilepsy has been reported to vary from 10% to over 50%. The authors reviewed all 32 patients diagnosed with PNES in our EEG–video monitoring unit over a period of 1 year, and only 3 (9.4%) had interictal epileptiform discharges to support a coexisting diagnosis of epilepsy. Thus, the authors believe that only a small proportion of patients with PNES have coexisting epilepsy.
