Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background :

Psychiatric comorbidities are common in epilepsy, affecting 50 to 70% of patients, especially when the epilepsy is focal and drug-resistant. Among these comorbidities, psychotic disorders (involving hallucinations and delusions) affect 8% of patients - that is, eight times more frequently than in the general population. Currently, the links between epilepsy and psychotic disorders are poorly understood and often overlooked by physicians, which impacts the mental health care of patients with epilepsy and leads to underdiagnosis.

The aim of this research is to determine whether there are differences in epileptic symptoms between patients with a psychotic comorbidity and those without.

Study design :

The main objective of this research is to better understand whether certain emotional epileptic symptoms are associated with a higher risk of developing psychotic symptoms.

The secondary objectives of this study are to investigate whether the level of consciousness during seizures is associated with a higher risk of developing psychotic symptoms.

To meet these objectives, the study will include patients who (1) have epilepsy, (2) were hospitalized in the video-EEG unit of the Neurology Department at Central Hospital for seizure recording, and (3) underwent a psychiatric evaluation in the context of epilepsy between January 1, 2016, and April 1, 2025.

The study will take place at the University Hospital Center (CHRU) of Nancy, in the Neurology Department, within the video-EEG unit led by Professor Louis Maillard. The research will involve comparing epileptic symptoms between the group of patients without psychosis and the group of patients with psychosis.

Data collection will cover the five days of video-EEG hospitalization, along with information from the psychiatric evaluation, for a total duration of approximately one week per year.

Information for participants:

As part of the routine medical care, data is collected in medical records to ensure appropriate follow-up. For the purposes of this research, data from the medical record will be collected.

No identifying information (such as name, initials, full date of birth, address, or social security number) will be collected.

No additional visits or examinations will be required. Patients will not be contacted or asked to provide any new information.
