What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study investigates whether brain signals can be recorded at home in people with essential tremor who have a deep brain stimulation (DBS) device. The goal is to see if these recordings are clear enough to understand how the brain responds to stimulation during rest and movement. Participants will have their brain activity recorded weekly over several months, with the stimulation turned on and off. The findings could help doctors personalize DBS settings for better tremor control.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Recordings of thalamic activity
What this could lead to
If successful, this could improve how deep brain stimulation is tuned for essential tremor, potentially leading to more personalized and effective therapy.
What could go wrong
This is a small, early-stage study focused on signal quality, not treatment outcomes. It may not lead to immediate clinical changes, and the recordings might not be reliable enough.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 75 years

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Advanced disabling and drug-resistant tremor * Receiving deep brain stimulation treatment with implantation of the PERCEPT™ device according to standard care * Chronic progressive cardiac, renal, hematological or pulmonary diseases under treatment. * Patient aged between 18 to 75 years * Normal brain MRI * MATTIS score ≥ 130/144 or MOCA ≥ 24/30 * Subject affiliated with or benefiting from a social security plan * Free, informed and written consent signed by the participant and the investigator (at the latest on the day of inclusion and before any examination required by the research) Exclusion Criteria: * Major depressive syndrome (Beck scale \> 20) * MRI showing significant brain atrophy or significant hypersignals * Pregnant or breastfeeding women * Being unable to give personal consent * Be subject to a measure of legal protection (curatorship, guardianship) or placed under judicial protection.
