Adaptive DBS for personalized Parkinson's therapy
This study tests a new feature in your Medtronic DBS device that automatically adjusts stimulation based on brain signals. It aims to improve symptom control for people with Parkinson's disease.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06343558Recruiting
Gait and balance study for rare neurological diseases
This study looks at how people with rare or common neurological diseases walk and keep their balance. You will be asked to do simple walking and standing tasks to help doctors understand these problems better.
Milan, MilanAges 18–80 - NCT03233646Recruiting
Retina scans in memory and nerve disorders
This study uses pictures of the back of your eye (retinal imaging) to look for differences in people with neurodegenerative diseases and compares them with people without these conditions. It may help researchers understand eye changes that could connect to brain or nerve health.
Durham, North CarolinaAges 18 years+ - NCT07411664Enrolling by invitation
Balance and walking study for stroke, Parkinson's, or multiple sclerosis
This study uses special motion-tracking tools to measure balance and trunk control in people with first-time stroke, Parkinson’s, or multiple sclerosis. It aims to understand how these conditions affect stability, which could help tailor rehabilitation.
Kaposvár, Somogy CountyAges 18–80 - NCT05347407Recruiting
Gut nerve cell biomarkers study for Parkinson’s risk
This trial studies nerve cell “biomarkers” from the gut to learn whether they can help detect Parkinson’s disease (or related conditions) earlier. You may be asked to undergo a colonoscopy to collect gut tissue for testing.
New York, New YorkAges 45–75 - NCT06695455Recruiting
Can music help people with Parkinson's swallow better?
This trial tests if a rhythmic sound cue can reduce rolling (a swallowing problem) in people with Parkinson's. If you have trouble with solid foods but not severe liquid aspiration, you may qualify.
Saint-Sébastien-de-Morsent, NormandyAges 18 years+ - NCT06868160Recruiting
Brain stimulation to improve walking in Parkinson's disease
This study tests whether different types of gentle electrical stimulation on the scalp can help improve walking and balance problems in people with Parkinson's disease. The goal is to find a better way to support rehabilitation.
MilanAges 45–85 - NCT06928519Recruiting
Entacapone with Madopar for early Parkinson's
This study tests whether adding entacapone to Madopar (a common Parkinson's medication) safely improves symptoms in people with early-stage Parkinson's. It aims to see if the combination works better than Madopar alone.

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.

Common questions
- Are there clinical trials for parkinson’s disease?
- Yes. Clin2 currently lists 740 recruiting parkinson’s 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 parkinson’s 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 parkinson’s 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.
