Healthy Volunteer Recruitment and Characterization for NINDS Studies
United States500 participantsStarted 2027-02-08
Plain-language summary
Background:
The National Institute of Neurological Disorders and Stroke (NINDS) often enrolls healthy volunteers in certain studies. These studies allow researchers to look for causes of diseases and disorders by comparing affected people to healthy ones. Prescreening lets volunteers participate in multiple studies without having to repeat the screening tests each time. Having a registry of prescreened volunteers also makes it easier for researchers to reach people willing to participate in their studies.
Objective:
To create a registry of healthy volunteers who have been prescreened for NINDS research studies.
Eligibility:
Healthy people aged 18 years and older.
Design:
Participants will have 1 clinic visit for prescreening. This visit will take about 5 hours. The visit may be spread across 1 to 3 days.
Participants will have the following procedures:
A physical exam, including height, weight, and vital signs.
A review of their medical history and medications. They will also provide personal data such as age, sex, and years of education.
An exam of their nervous system. This will include tests of their strength and reflexes, following an object with their eyes, and other tasks.
Cognitive tests. These tests will check their memory, attention, and thinking.
A magnetic resonance imaging (MRI) scan. They will lie on a table that slides into a cylinder; Magnetic fields will create images of their brain.
Handedness. They will complete a questionnaire about what hand they use for most tasks.
Participants may remain on the healthy volunteers list for 2 years. If they wish to participate longer, they will need to return to repeat all of the screening tests.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
To screen and create a temporary list of volunteers in good health for participation in NINDS studies (Volunteer List) in order to reduce costs, inconvenience to volunteers, and duplication of effort.
Timeframe: From enrollment/consent until withdrawal from the registry or study closure.
