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.

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 people with Parkinson's disease learn to understand speech and how that relates to their own speaking ability. Researchers will have 50 participants with Parkinson's do listening and speaking tasks to measure speech perception and production. The goal is to find links that could lead to new therapies for clearer speech and better understanding.

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 research could point toward new therapies that help people with Parkinson's speak more clearly and understand speech better.
What could go wrong
This is an early observational study with only 50 participants, so results may not apply to everyone with Parkinson's. It does not test a treatment, so direct benefits are not guaranteed.

This is an AI summary of the original study and may miss details. Read our disclaimer.
