Study brain and movement patterns in Parkinson’s or tremor
This study looks at brain signals, thinking, and movement behaviors in people who have Parkinson’s disease or essential tremor and are being considered for deep brain stimulation (DBS) surgery. It may help researchers better understand how DBS affects the brain and day-to-day function.
Birmingham, AlabamaAges 18 years+ - NCT04179695Recruiting
Testing a new communication aid to improve patient-centered care
This study tests a new tool meant to help patients and healthcare teams communicate better and support “patient-centered care.” You may be invited to use the tool and complete study activities during your neurology care visits.
LilleAges 18–90 - NCT04366804Recruiting
Testing two non-movement symptom questionnaires in Parkinson’s
This study checks whether two written questionnaires can reliably measure “non-motor” symptoms in people with Parkinson’s disease. It may help future care by making symptom tracking easier and more accurate.
BesançonAges 30–75 - NCT04735172Recruiting
Brain scan to compare Parkinson chemical signals in early patients
This study uses a special 7‑Tesla MRI brain scan to measure tiny chemical (metabolite) differences in specific deep brain areas. It compares newly diagnosed, early-stage Parkinson’s patients who are not on Parkinson medication with healthy volunteers.
Clermont-FerrandAges 18–75 - NCT05413291Recruiting
Study of movement disorders over time
This study follows people (or family members of people) who have or might have a movement disorder to better understand how symptoms change over time. You may be asked to attend study visits and complete study procedures for the duration of the study.

Compare antipsychotic medicines for Parkinson or Lewy body psychosis
This study compares two medicines—quetiapine and pimavanserin—in people with psychosis caused by Parkinson’s disease or Lewy body dementia, looking at how they work over time. You might join if you are starting an antipsychotic for the first time and your clinician can safely manage either option.
San Antonio, TexasAges Any age - NCT06098612RecruitingEarly Phase 1
PET imaging study for Parkinson's and related disorders
This study uses a new PET scan tracer called [11C]SY08 to take pictures of the brain in people with Parkinson's, multiple system atrophy, or dementia with Lewy bodies. It aims to see if this tracer can help better understand and tell apart these conditions.
Charlestown, MassachusettsAges 50–80 - NCT06460038RecruitingPhase 2
Medication study for constipation in Parkinson's
This study tests whether a medication called tenapanor can help relieve constipation in people with Parkinson's disease. If you have Parkinson's and have been struggling with constipation for at least 6 months, this trial may offer a new option to improve bowel regularity.
Waterloo, IowaAges 50–89 - NCT07569120Recruiting
Brain Chemistry and Aging: Healthy and Parkinson's Study
This research uses brain imaging scans to study how a chemical messenger in the brain (called noradrenaline) changes as people age and in Parkinson's disease. The goal is to better understand how this brain system works and may help develop future treatments.
BronAges 20–80 - NCT06505460Recruiting
Brain stimulation for Parkinson's freezing of gait
This study is testing if two brain-stimulation treatments—deep brain stimulation (DBS) or focused ultrasound—can help reduce freezing of gait (a common, frustrating symptom where your feet feel stuck when walking) in people with Parkinson's. Researchers will use brain scans and electrical recordings to understand how these treatments work.
TaichungAges 20–90 - NCT06519279Recruiting
Freezing of gait study for Parkinson's patients
This study looks at how Parkinson's disease affects freezing of gait (a sudden feeling of being stuck while walking). It may help researchers better understand this symptom and improve future treatments. You may be able to join if you can walk 10 meters without help and don't have a deep brain stimulator.
Tel AvivAges 18 years+ - NCT06596187Recruiting
Study of muscle tightness in spinal cord injury and Parkinson's
This study looks at muscle tightness (hypertonia) in people with spinal cord injury, Parkinson's disease, and healthy volunteers. It aims to better understand and measure different types of stiffness to improve treatments.
TaoyuanAges 20 years+ - NCT06684782Recruiting
Restless leg syndrome in Thai Parkinson's patients
This trial is looking at how common restless leg syndrome is in people with Parkinson's disease in Thailand. It aims to better understand the link between the two conditions so doctors can improve care for people with both.
Bangkok, BangkokAges 18–80 - NCT02071134Recruiting
Registry study for Vercise deep brain stimulation patients
This study keeps a record of people who receive the Vercise deep brain stimulation system. It helps doctors learn how the treatment is used in real-world care and how patients do over time.
Aliso Viejo, CaliforniaAges 18 years+ - NCT06815263Recruiting
Listener training to understand speech in Parkinson's
This trial tests a listener training program to help people better understand speech that is hard to understand due to Parkinson's disease. It may help if you have Parkinson's and a speech problem called hyperkinetic dysarthria.
Tallahassee, FloridaAges 18 years+ - NCT06891703RecruitingEarly Phase 1
PET imaging study for Parkinson's and related conditions
This trial uses a new imaging agent (like a dye) to see signs of Parkinson's disease in the brain. If you have Parkinson's or a related condition like Lewy body dementia or multiple system atrophy, this scan may help researchers better understand these illnesses.

Brain imaging study of freezing of gait after deep brain stimulation
This trial is for people with Parkinson's disease who experience freezing of gait (feeling like your feet are stuck to the floor) and are already scheduled to have deep brain stimulation surgery. The study will use MRI brain scans to understand how the surgery helps improve walking.

Common questions
- Are there clinical trials for parkinson’s disease?
- Yes. Clin2 currently lists 739 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.
