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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks for brain scan markers that might predict thinking and memory changes after Deep Brain Stimulation (DBS) in people with Parkinson's disease. Researchers will use MRI scans before surgery and cognitive tests after surgery in 55 Parkinson's patients, plus compare them to 25 healthy controls. The goal is to better understand why some people experience cognitive decline after DBS.

What this could mean

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

What this could lead to
If successful, this could help doctors predict which Parkinson's patients might experience memory or thinking problems after Deep Brain Stimulation, allowing for better treatment planning.
What could go wrong
This is an observational study, not a treatment trial. It aims to understand cognitive decline, not prevent or reverse it. Results may not apply to all patients.
