Comparing awake and asleep deep brain stimulation for essential tremor

Official title: The TREMBLE Study: Multicentre Randomized Controlled Trial of Awake Versus Asleep Tractography Based Deep Brain Stimulation for Essential Tremor

Run by Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT05968976 · Data updated 2026-11-12

This study is testing whether deep brain stimulation done while patients are awake works better than when it's done while they're asleep for people with essential tremor who haven't found relief with medication.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with idiopathic essential tremor that severely limits their daily functioning despite optimal medication.

Probably not a fit

Patients with previous tremor-related neurosurgery or those with contraindications for DBS surgery may not benefit from this study.

What this trial studies

This clinical trial aims to compare the effectiveness of awake versus asleep deep brain stimulation (DBS) for patients with essential tremor who have not responded adequately to medication. The study will utilize advanced imaging techniques to visualize the target area in the thalamus during surgery. Participants will be assessed for tremor reduction and quality of life six months post-surgery, alongside evaluating operation time and patient satisfaction. The trial is multicenter, involving several hospitals in the Netherlands.

Why it matters

Potential benefit: If successful, this study could provide a less burdensome surgical option for patients with essential tremor, improving their quality of life.

How similar studies have gone: While deep brain stimulation has been established as an effective treatment for essential tremor, the comparison of awake versus asleep techniques is a novel approach that has not been extensively tested.
