Brief Summary

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

The study aims to compare the safety and effectiveness of deep brain stimulation of the hippocampus and the anterior nucleus of the thalamus for reducing the frequency of seizures in patients with bilateral temporal lobe epilepsy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The outcome of resective surgery for bilateral temporal lobe epilepsy (BTLE) is poor. Neuromodulation such as deep brain stimulation is an alternative therapy for patients with drug-resistant epilepsy, especially for those not suitable for resective surgery. This prospective, randomized, open-label trial aims to compare the effectiveness of deep brain stimulation of the hippocampus and the anterior nucleus of the thalamus for bilateral temporal lobe epilepsy.
