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 Results may not be published yet.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

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.

Summary

This study looks at how deep brain stimulation (DBS) affects sleep in people with Parkinson's disease. Twenty participants who already have a DBS implant will spend two nights in a sleep lab—one night with the device on and one night with it off. Researchers will measure sleep quality, daytime sleepiness, and motor symptoms to see if there is a difference.

What this could mean

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

Active substance
Deep brain stimulation (DBS) device turned on or off during sleep
What this could lead to
If successful, this study could help doctors understand how DBS affects sleep in Parkinson's disease, potentially leading to better sleep management strategies.
What could go wrong
This is a small, early-stage study with only 20 participants, so results may not apply to everyone. It is designed to gather knowledge, not to test a new treatment.
