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 This study
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 Results may not be published yet.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

Summary

This study explores whether wearing prismatic goggles that shift vision can improve emotional awareness (alexithymia) and visual-spatial abilities in people with Parkinson's disease. Researchers will also use brain scans and tear tests to understand how the brain adapts and to find new biomarkers. The trial involves 126 participants with mild Parkinson's and aims to see if this simple, non-invasive technique can boost quality of life.

What this could mean

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

Active substance
prismatic adaptation (special goggles that shift vision)
What this could lead to
If it works, this could offer a non-invasive way to ease certain Parkinson's symptoms like emotional numbness and spatial awareness issues.
What could go wrong
This is an early-stage study with only 126 participants, so results may not apply widely. The intervention is experimental and may not produce lasting benefits.

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.

Participants

About 126 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2024

Expected to finish

Feb 2026

An estimate. End dates often move.

Lead sponsor

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.
