  • Title: Outcome of patients with psychogenic nonepileptic seizures with limited resources: A longitudinal study.
    Author: Asadi-Pooya AA, Ziyaee F.
    Journal: Seizure; 2018 Jul; 59():1-4. PubMed ID: 29709720.
    Abstract:
    PURPOSE: The aim of the current study was to investigate the long-term outcome of patients with psychogenic nonepileptic seizures (PNES) and factors potentially associated with their outcome in Iran. METHODS: We investigated all patients with PNES admitted to the epilepsy monitoring unit at the Shiraz Comprehensive Epilepsy Center from 2008 through 2013. Patients included in this study had a confirmed diagnosis of PNES. In a phone call interview to the patients in December 2017, we obtained the following information: seizure outcome (seizure-free during the past 12 months or not), history of receiving any psychotherapy after confirming their diagnosis in the past, and number of psychotherapy sessions the patient had received. RESULTS: Eighty-six patients (54 females and 32 males) met the inclusion criteria. Seventy-four (86%) patients did not receive appropriate psychotherapy. Forty-seven (54.7%) patients were seizure-free during the past 12 months. Age at onset (P = 0.02), education (P = 0.01), and taking psychiatric drugs (P = 0.007) were associated with this outcome. CONCLUSIONS: Resources to treat patients with PNES are limited in Iran; however, more than half of the patients became free of seizures. Lower education, comorbid psychiatric problems, and a later age at the onset of seizures may affect the seizure outcome in patients with PNES. Well-designed multi-center cross-cultural long-term studies should address factors associated with outcome in patients with PNES, considering that seizure frequency should not be the only outcome measure.
