Overview
The TIPI2 study is a blood and tissue collection protocol to create an annotated biorepository to support research in drug-resistant epilepsy.
The aim of the study will be to identify new pathophysiological pathways. For this purpose, the investigators will investigate with a multimodal approach blood and brain samples from patients undergoing a surgery for focal drug-resistant epilepsy. The adult patients will be enrolled either during the pre-surgical evaluation or right before the surgery.
Description
This study aims to investigate blood and brain samples from patients with drug-resistant epilepsy in order to identify new pathophysiological biomarkers.
The investigators will first conduct multimodal research, including:
- electrophysiological analyses
- immunohistochemistry and genetic studies
- biochemistry analyses
Samples will be stored at -80°C for future research.
Patients will undergo a follow-up evaluation within the 36 months following the surgery. New clinical data and biological samples will be collected then.
Eligibility
Inclusion Criteria:
- 18 yo or above
- patients with a focal drug-resistant epilepsy
- patients hospitalized for a pre-surgical evaluation or for an epilepsy surgery
- consent obtained from the patient, or legally authorized representative
- affiliated to a social security system
Exclusion Criteria:
- None
