Psychogenic nonepileptic seizures

Abstract

Introduction

Psychogenic nonepileptic seizures (PNES) are defined as a somatoform conversion disorder manifesting as paroxysmal events not associated with electroencephalographic (EEG) epileptiform correlates. This entity is poorly understood and often misdiagnosed as epilepsy. It is important to recognize that misdiagnosis leads to inappropriate use of antiepileptic drugs, which may worsen the course of the disease.

Recent studies have suggested that the frequency of psychogenic nonepileptic seizures ranges from 10 to 23% of referrals to a pediatric epilepsy center, as well as 60% of children with PNES achieve symptom improvement and event freedom of symptoms following appropriate treatment.

Objectives

The aim of this study is to conduct a literature review of studies which the purpose was better understand the etiologies, features, and care outcomes of psychogenic nonepileptic seizures (PNESs) in a pediatric setting.

Conclusion

A early identification of the risk factors for comorbid psychopathology, diagnosis and appropriate care for PNESs reduces inappropriate medical investigation and therapy, expedites rates of remission, and decreases health-care utilization in a pediatric setting.
