Purpose: The purpose of this study was to determine if patients with episodes of prolonged psychogenic nonepileptic seizures or pseudostatus are different from those with psychogenic nonepileptic seizures (PNESs) without prolonged attacks regarding their demographic and clinical characteristics and factors potentially predisposing to PNESs.
Methods: In this prospective study, all patients with a clinical diagnosis of PNESs (based on ictal recordings) were recruited at the outpatient epilepsy clinic at Shiraz University of Medical Sciences from 2008 through 2013. The epileptologist interviewed all the patients. We compared the demographic and clinical characteristics of patients with PNES-status with those with PNES-only.
Results: Two hundred and eleven patients were studied. Forty-nine patients (23.2%) reported episodes of PNES-status, and 162 patients (76.8%) did not report PNES-status. There were no significant differences between these two groups of patients regarding the demographic and clinical characteristics and factors potentially predisposing to PNESs.
Conclusion: Psychogenic nonepileptic seizure status (PNES-status) is relatively common among patients with PNESs. It seems that patients with PNES-status are not different from those with PNES-only, at least regarding the demographic and clinical characteristics and factors potentially predisposing to PNESs.

The potential of dietary interventions, particularly the use of the ketogenic diet in patients with Psychogenic Non-Epileptic Seizures (PNES), remains underexplored. This study aimed to assess the feasibility of a 6-week ketogenic diet (Modified Atkins Diet, MAD) intervention in adult patients with PNES and to compare its effects on PNES frequency and other variables against a control healthy diet (CD). A feasibility pilot randomized controlled trial was conducted at a tertiary neurology hospital, enrolling outpatients diagnosed with PNES and assigning them to either MAD or CD.

Objective: Medical personnel show difficulty in differentiating psychogenic nonepileptic seizures (PNES) from epileptic seizures (ES). The purpose of this study was to conduct an initial feasibility assessment of the global dynamic impression (GDI) principle and to evaluate its effectiveness in enabling the diagnosis of epileptic versus psychogenic seizures using video footage of events, even by untrained personnel METHODS: We based this study on video footage showing five videos of PNES and five ES videos. We asked physicians and nurses from the emergency department, internal medicine department, neurology department, and medical students to classify the videos before and after learning the GDI principle.

In this retrospective study, patients with PNES who requested driving privileges or reported having resumed driving were compared to those who did not on measures of depression, anxiety, PTSD, and cognitive flexibility/motor speed.

Objectives: The ability to differentiate epileptic- and non-epileptic events is challenging due to a lack of reliable molecular seizure biomarker that provide a retrospective diagnosis. Here, we use next generation sequencing methods on whole blood samples to identify changes in RNA expression following seizures.
Methods: Blood samples were obtained from 32 patients undergoing video electroencephalogram (vEEG) monitoring.
