Psychiatric comorbidity in veterans with psychogenic seizures

► We reviewed psychiatric diagnosis in veterans with psychogenic seizures (PNES). ► PTSD was strongly predictive of a diagnosis of PNES in veterans. ► PTSD was the only significant predictive psychiatric diagnosis for PNES. ► Depression and substance abuse do not differentiate veterans with PNES vs. epilepsy. ► These results may aid in early recognition of PNES in veterans.
