About

Using multimodal imaging technology, this study aims to explore the characteristics of epileptogenic foci in patients with drug-resistant epilepsy and identify key network nodes (such as central nodes) to provide more assistance for the diagnosis of drug-resistant epilepsy.

Full description

This study is a prospective observational cohort study. It prospectively recruited 50 patients with drug-resistant epilepsy from the Epilepsy Center of the Department of Neurology at Xijing Hospital, all aged 18 years or older. It collected general information and clinical baseline data such as magnetic resonance imaging; gathered multimodal imaging data once; analyzed the characteristics of epileptogenic foci in patients with drug-resistant epilepsy; and performed statistical analysis.

Enrollment: 50 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Aged ≥18 years old;
2. Meet the 2010 International League Against Epilepsy (ILAE) diagnostic criteria for drug-resistant epilepsy;
3. Duration of epilepsy ≥2 years, with an average seizure frequency of ≥2 times per month in the 3 months prior to enrollment;
4. Adequate intake of two or more anti-epileptic drugs, with no intervention in the treatment plan during the trial period;
5. Capable of cooperating to complete treatment and related examination items; The patient and family fully understand and voluntarily sign the informed consent form.

Exclusion criteria

1. In a state of continuous epileptic seizures;
2. Complicated with severe infections, cerebrovascular diseases, malignant tumors, and other diseases, accompanied by severe dysfunction of the heart, liver, kidney, or other organs, or with mental disorders, or with uncorrectable hyperglycemia, or 3.patients on long-term use of corticosteroid medications;

4.Pregnant or lactating women; 5.Contraindications for PET, MR, EEG examinations; 6.Patients with examinations (with ferromagnetic metal implants in the body; high fever); 7.Participating in other clinical trials at the same time; 8.The patient or family withdraws the informed consent form.

Trial design

50 participants in 1 patient group

Intractable epilepsy patients.

Description:

Based on the hybrid fusion technology of PET-fMRI-EEG, this study explores the characteristics of brain network damage in refractory epilepsy, identifies key network nodes (such as central nodes), and provides more assistance for the diagnosis of drug-resistant epilepsy.
