Prospective Study of Postictal Psychotic Symptoms Occuring After Video-EEG Monitoring in Focal Epilepsies

Psychotic disorders are up to eight times more prevalent in patients with epilepsy compared to the general population. Among them, postictal psychosis (PIP) is a severe complication of focal epilepsy, characterized by a brief psychotic episode emerging days after a seizure. This project investigates a potentially attenuated and under-recognized manifestation-postictal psychotic symptoms (PPs)-that may arise following hospitalization in a video-EEG monitoring unit and might serve as an early indicator for future PIP. We hypothesize that the incidence of PPs is substantially higher than the 3% PIP prevalence reported in the literature and that their occurrence correlates with the intensity of epileptic activity triggered during video-EEG monitoring. The study has three main objectives: (1) to determine the incidence of PPs in patients with drug-resistant focal epilepsy, (2) to identify predictive factors associated with PPs, and (3) to assess the validity of the PQ-16 screening tool in this clinical context. A prospective monocentric study will be conducted in the video-EEG unit of Nancy University Hospital. One hundred and ten patients hospitalized for at least five days will be included. Psychiatric assessments will include standardized clinical interviews, Brief Psychiatric Rating Scale (BPRS) scoring, and self-report questionnaires. These evaluations will take place at three timepoints: baseline (V1), 3-5 days post-discharge (V2), and two months post-discharge (V3). This study aims to facilitate the early identification of PPs and support the development of preventive strategies, ultimately improving psychiatric care and overall management in patients with epilepsy.

Psychological and Psychiatric Assessment in Patients Eligible for Epilepsy Surgery

The aim of the study is to describe the socio-demographic, clinical, psychological, and psychiatric characteristics of patients with drug-resistant focal epilepsy eligible for epilepsy surgery and any changes in these parameters over time after surgery. Additionally, the study seeks to describe the levels of quality of life, dissociative experiences, prevalence of various psychiatric symptoms, irritability, depressive symptoms, anxiety symptoms, and stigma perception in patients with drug-resistant focal epilepsy eligible for epilepsy surgery and any changes over time after surgery.

Real-world Clinical Response to Cenobamate Early add-on in France, Germany and Spain

Aim of the study is to better characterize the clinical profile of adjunctive cenobamate by collecting data from the current standard clinical practice in France, Germany, and Spain, to describe the real-world clinical response among adult patients affected by focal epilepsy not adequately controlled despite a history of 2 or 3 ASMs before starting treatment with cenobamate (including previous and concomitant ASMs).
