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 Results may not be published yet.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.

Summary

This study tests whether a mild electrical brain stimulation technique called tDCS can improve swallowing difficulties in people with Parkinson's disease. 58 participants will receive either real or sham tDCS alongside standard swallowing therapy. Researchers will measure changes in swallowing function and brain activity using video X-rays and brain scans.

What this could mean

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

Active substance
transcranial direct current stimulation (tDCS) device
What this could lead to
If it works, this could offer a non-drug way to improve swallowing safety and quality of life for people with Parkinson's disease.
What could go wrong
This is a small, early-stage trial with only 58 people. The improvement may be modest, and the effects might not last long-term.
