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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is creating a large, open-access database of clinical, motor, and non-motor information from nearly 1,000 people with Parkinson's disease and healthy controls in Brazil. Researchers will collect data through questionnaires, movement tests, and clinical scales. The goal is to better characterize Parkinson's and support future research and technology development.

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 database could help researchers better understand Parkinson's disease and develop new tools for diagnosis and treatment.
What could go wrong
This is an observational study, not a treatment trial. It collects data but does not test any therapy, so direct patient benefits are not expected.

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

Inclusion Criteria: * Experimental group: (i) present a neurological diagnosis of Parkinson's disease; (ii) be classified between stages I to IV of the Hoehn \& Yahr Scale; (iii) have central visual acuity equal to or greater than 20/40 (equivalent to 0.50) in each eye or equal to or greater than 20/30 (equivalent to 0.66) in one eye according to the Snellen scale. * Control group: (i) not having a neurological diagnosis of Parkinson's disease or other neurological disease that resembles PD; (ii) have central visual acuity equal to or greater than 20/40 (equivalent to 0.50) in each eye or equal to or greater than 20/30 (equivalent to 0.66) in one eye according to the Snellen scale. Exclusion Criteria: For both groups, individuals who have other neurological or musculoskeletal diseases that interfere with the execution of the tests will be excluded.
