Non-epileptic psychogenic seizures: a renewal approach of conversion disorders. Psychogenic non-epileptic seizures (PNES) are characterized by a paroxystic modification of behaviour or consciousness that resemble to an epileptic seizure. They are classified as dissociative or somatoform disorders. Their diagnostic remains difficult and the recording of a typical event through video-EEG is the gold standard. PNES are a symptom of the underlying disease related to disturbances in the management and regulation of emotions. Thus, the predisposing, the precipitating and the perpetuating factors must be evaluated carefully. A multidisciplinary diagnosis announcement is an essential and effective therapeutic step and treatment has to be adapted case by case.

Introduction: Functional neurological disorders (FND) are conditions marked by disruptions in brain network function without structural abnormalities. Sleep disturbances, though under-researched, are commonly observed in FND patients and may worsen symptoms and overall health.
Methods: This systematic review had been registered prospectively in PROSPERO with the registration number: CRD42023446306.

Epileptic seizures, which are often accompanied by a reduction in vigilance, are a common emergency. Every first-time epileptic seizure should be investigated further. Particular attention should be paid to whether it is an acute symptomatic seizure, which is an acute event characterized by a metabolic disorder or acute cerebral damage within a certain period of time, or possibly epilepsy.

Psychogenic non-epileptic seizures (PNES) are episodic events that bear a resemblance to epileptic seizures (ES) in their outward manifestations, yet they lack pathological electroencephalographic (EEG) activity during the ictal phase. In the Diagnostic and Statistical Manual 5th Edition (DSM-5), PNES is designated as "Functional Neurological Symptom Disorder with seizures". Individuals diagnosed with PNES commonly present with concurrent psychiatric disorders, notably depression, panic disorder, and chronic anxiety.

Objective: Numerous studies have been conducted investigating the effects of antiseizure medications (ASMs) on cognitive functions, and the cognitive side effects of some ASMs have been demonstrated. However, data on whether tolerance to these side effects develops over time is insufficient. The aim of this study is to evaluate the reversibility of cognitive impairments caused by ASMs in patients, utilizing event-related potentials (ERPs) and the Montreal Cognitive Assessment (MoCA) test.

Objective: Psychogenic non-epileptic seizures (PNES) mimic epileptic seizures without electroencephalographic correlation. Although classified as psychiatric disorders, their neurobiological or structural basis remains unclear. This study aimed to assess the prevalence and characteristics of MRI abnormalities in patients with PNES and those with comorbid epilepsy, compared to the general population, to enhance radiological evaluation and management.
