What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Not yet recruiting This study
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 Results may not be published yet.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.

Summary

Researchers are checking whether a Turkish translation of the Parkinson Neuropsychometric Dementia Assessment (PANDA) gives consistent and accurate results in people with Parkinson's disease. About 100 Turkish-speaking patients will complete the questionnaire, which tests memory, verbal fluency, visuospatial skills, and delayed recall. A subgroup will take the test again later to see if scores stay stable over time. The goal is to provide doctors with a reliable tool for detecting cognitive decline in this population.

What this could mean

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

Active substance
the Turkish version of the Parkinson Neuropsychometric Dementia Assessment (PANDA), a cognitive screening questionnaire
What this could lead to
If the Turkish PANDA proves reliable, doctors could use it to spot thinking and memory problems in Turkish-speaking people with Parkinson's disease earlier and more accurately.
What could go wrong
This is a small, single-country validation study, so the results may not apply to other languages or populations. A screening questionnaire can flag possible cognitive issues but cannot diagnose dementia on its own.
