Abstract

BACKGROUND: Psychogenic non-epileptic seizures (PNES) are classified with other functional neurological symptoms as 'Conversion Disorder', but there are reasons to wonder whether this symptomatology constitutes a distinct entity.

METHODS: We reviewed the literature comparing PNES with other functional neurological symptoms.

RESULTS: We find eight studies that directly examined this question. Though all but one found significant differences-notably in presenting age, trauma history, and dissociation-they were divided on whether these differences represented an important distinction.

CONCLUSION: We argue that the aetiological and mechanistic distinctions they support, particularly when bolstered by additional data, give reason to sustain a separation between these conditions.
