Clinical differences between patients with psychogenic nonepileptic seizures and functional motor disorder

Abstract

Objectives: Why a patient might present with psychogenic nonepileptic seizures (PNES) as opposed to another functional neurological symptom is unknown. A recent review suggested that patients with PNES and functional motor disorders (FMD) differ on demographic and clinical factors of potential aetiological and mechanistic significance, arguing they might represent different disorders, though direct comparisons are limited. We sought to determine whether these factors differed in patients presenting with FMD and PNES at our clinic, as well as whether preceding medical complaints would differ between the two, particularly those affecting the limbs or head. Methods: A retrospective chart review..
