Recruiting studies
- NCT07790744Recruiting
Brain imaging study for early Parkinson's signs in people with REM sleep disorder
This study uses MRI scans to look at the brain in people with REM sleep behavior disorder (RBD), a condition that can be an early sign of Parkinson's disease. By comparing them with healthy volunteers, researchers hope to find early markers of Parkinson's that could lead to earlier diagnosis and treatment.
HvidovreAges 18 years+ - NCT06993142Recruiting
Slowing Parkinson's Early With Exercise
This trial tests whether a specific exercise program can slow the early stages of Parkinson's disease in people who have a genetic risk (LRRK2 or GBA variants). You will use a smartphone app to guide your exercise from home.
Rochester, New YorkAges 50 years+ - NCT06193252Recruiting
Exercising to slow Parkinson's in iRBD
This study tests whether a specific amount of exercise can slow the development of Parkinson's disease in people who have a sleep condition called iRBD. If you have iRBD and are not very active, researchers will help you start a personalized exercise program and track your progress with a smartphone app.

BioFINDER 2 study for healthy aging and memory problems
This study uses brain scans and a spinal fluid test to better understand memory and thinking changes in different groups, from people with healthy thinking to early or established dementia. If you qualify, it may help researchers learn what’s driving these conditions and how they progress.
ÄngelholmAges 20–100 - NCT04724941Recruiting
Screening for alpha-synuclein in early Parkinson’s risk
This study looks for changes in a protein called alpha-synuclein in people who may be in the early “prodromal” stage before Parkinson’s symptoms fully appear. It may help researchers find early markers and understand who is more likely to develop Parkinson’s disease.
KielAges 50–99 - NCT05934188Recruiting
Study how gut signals relate to brain aging and diseases
This study looks at how the gut may influence the brain in normal aging and conditions like Alzheimer’s, Parkinson’s, and multiple sclerosis. It may help researchers understand new ways to measure or treat these brain changes over time.
Venice-Lido, VeniceAges 20–90 - NCT06582121Recruiting
Sleep disorders in early and advanced Parkinson's disease
This study looks at sleep problems in people with Parkinson's disease, people with REM sleep behavior disorder (a condition that causes acting out dreams), and healthy volunteers. The goal is to understand how sleep is affected in early and full Parkinson's disease.
Clermont-FerrandAges 18 years+ - NCT06869135Recruiting
Saliva testing for brain diseases
This trial is collecting saliva samples from people with Alzheimer's, Parkinson's, or other brain diseases to find new ways to diagnose them. It may help improve early detection.
Florence, FIAges 45 years+ - NCT07324330Recruiting
Slowing cognitive decline with exercise in iRBD
This study tests if increasing physical activity can help slow down cognitive (thinking) decline in people with iRBD, a sleep disorder that often leads to Parkinson's or dementia. You'll use a smartphone and a FitBit to track your activity and receive coaching.
Bonn, North Rhine West-FaliaAges 50–80 - NCT06745011Enrolling by invitation
Parkinson's signs in people with nerve damage
This study looks for early signs of Parkinson's disease in people who have nerve damage in their hands and feet (polyneuropathy) with no known cause, along with drops in blood pressure when standing up. It aims to understand if these early symptoms might predict future Parkinson's.
Aarhus, JutlandAges 18–85 - NCT06456684Recruiting
AV133 PET scan study in early Parkinson's disease
This study uses a special PET scan to look at a protein (VMAT2) in the brain that is linked to Parkinson's disease. It helps researchers understand early changes in people with newly diagnosed Parkinson's or those at high risk of developing it.
Beijing, Beijing MunicipalityAges 30 years+ - NCT04701177Enrolling by invitation
Smartphone-based study of brain biomarkers in memory clinic patients
This observational study follows people with (or at risk for) Alzheimer’s-related brain changes and a comparison group without them. It uses clinic visits, cognitive testing, questionnaires, and possibly a spinal fluid test to better understand brain biomarkers and how they relate to thinking and daily life.
Corfu, CorfuAges 45 years+ - NCT07679256Recruiting
Digital and brain markers for early Parkinson's diagnosis
This study uses digital tools and brain markers to detect Parkinson's disease early. It includes healthy people, those with early Parkinson's, and those with REM sleep behavior disorder (a possible early sign).
Fuzhou, FujianAges 40–80 - NCT04888364Recruiting
French study following people with Parkinson’s and related conditions
This study follows people with Parkinson’s disease, certain Parkinson-like conditions, and some people at higher risk. It helps researchers learn how these illnesses start and progress, which may lead to better earlier detection and care.
ParisAges 10 years+ - NCT06957418RecruitingPhase 2
Alzheimer's tau drug study for early stage patients
This trial tests a treatment targeting tau protein buildup in the brain for people with early Alzheimer's. You may join if you have memory or thinking changes but are still living independently, and brain scans show both amyloid and tau clumps.
San Francisco, CaliforniaAges 50–80 - NCT03623672Enrolling by invitation
Study for early signs of Parkinson-related brain changes
This study enrolls people with idiopathic REM sleep behavior disorder, a sleep problem that can come before Parkinson’s disease or related conditions. It aims to better understand early (“prodromal”) changes so future treatments can be targeted earlier.
Sun City, ArizonaAges 18 years+ - NCT06875739Enrolling by invitation
Saliva test for early diagnosis of brain diseases
This study tests whether a saliva sample can help tell the difference between brain diseases like Alzheimer's, Parkinson's, and related conditions. By using a special laser technique, researchers hope to find a quick, non-invasive way to make an earlier and more accurate diagnosis.
CagliariAges 60–85 - NCT07477431RecruitingPhase 2
Testing levetiracetam for those at risk of Alzheimer's
This trial tests if a medication called levetiracetam (a drug usually used for seizures) can help protect memory in people who are at higher risk for Alzheimer's but do not yet have memory problems. It involves brain scans and cognitive tests to see if the drug can reduce overactive brain activity linked to memory loss.
Toronto, OntarioAges 55–85 - NCT05826457Enrolling by invitation
Study for early RBD as a possible Parkinson’s risk
This study looks at people with REM sleep behavior disorder (RBD), confirmed by a sleep test, who may be in the early “prodromal” stage before Parkinson’s or related diseases. It also enrolls healthy controls to compare results from brain and body testing to better understand who is at risk.

- Yes. Clin2 currently lists 25 recruiting prodromal parkinsons disease studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a prodromal parkinsons disease trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a prodromal parkinsons disease trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
