What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 aims to build a comprehensive 'physiological brain atlas' by collecting electrical and other data from patients undergoing stereotactic brain surgery for conditions like Parkinson's disease, OCD, and epilepsy. The goal is to map this information onto a standard brain template, which could help doctors understand and treat brain disorders more precisely. The study will include up to 5,000 patients aged 6 to 90 who are already scheduled for such procedures.

What this could mean

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

Active substance
Stereotactic brain procedures
What this could lead to
If successful, this could create a detailed brain atlas that helps doctors target treatments like deep brain stimulation more precisely for conditions such as Parkinson's disease and epilepsy.
What could go wrong
This is an observational data-collection effort, not a treatment trial, so it may not directly improve outcomes. The atlas's usefulness depends on complex data analysis and may not generalize to all patients.

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.

Who is studied

Patients who have already consented to having a stereotactic brain procedure for surgical treatment or implantation of a device to treat any brain disease. This includes patients who are undergoing normal neurosurgical care for the treatment of their movement disorder (like tremor and Parkinson's disease), epilepsy, pain, or psychiatric disease.
