Psychogenic nonepileptic seizures (PNES) are sudden, involuntary seizure-like attacks that, unlike epileptic seizures, are not related to electrographic ictal discharges and are psychological in nature. Psychogenic nonepileptic seizures presenting symptoms mimic a wide array of nervous system dysfunctions, as they involve changes in behavior, motor activity, sensation, cognitive, and autonomic functions. Spontaneous paroxysms of laughing resembling gelastic seizure have only exceptionally been reported as main symptom of PNES. Here, we describe the cases of two patients with a prolonged history of laughter attacks mistaken for epilepsy and unresponsive to AED treatment. Brain MRI and interictal EEG were unremarkable. Video-EEG monitoring allowed us to document the spontaneous and suggestion-induced habitual episodes that were then diagnosed as PNES.

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.
