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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how Parkinson's disease affects the brain's ability to control actions, like stopping or switching tasks. Researchers will have 50 people with Parkinson's do joystick tasks while on their usual dopamine medication. The goal is to better understand these brain processes, not to test a new treatment.

Study facts

What this study's own registry entry says, in plain language.

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 50 people

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

Started

Apr 2024

Expected to finish

Nov 2027

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.

Ages

18 to 80 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

For Parkinson's Disease Patients: Inclusion Criteria: * Diagnosis of Parkinson's Disease by a movement disorder neurologist * Levodopa responsive with clearly defined "on" periods, with at least 30% improvement in UPDRS III scores on vs off * Willingness and ability to complete the behavioral experiments for up 3.5 hours * No vision or hearing problems that impair ability to participate with the proposed tasks as assessed by the study investigators Exclusion Criteria: * Patients with history of secondary Parkinsonism, stroke, or progressive central nervous system disease other than Parkinson's Disease * Patients with a disease or condition that prevents understanding or communication of informed consent, study demands, and testing protocol including cognitive decline, diagnosed forms of dementia, significant memory impairment (MoCA\<23), or hearing loss that prevents adequate communication with researcher For Healthy subjects: Inclusion Criteria: * No history any diagnosed neurological disease(s), including movement disorders or cognitive decline * No vision or hearing problems that impair ability to participate with the proposed tasks as assessed by the study investigators
