Parkinson care team program for people living at home
This study tests whether “Parkinson specialized teams” can improve care for people with Parkinson’s disease who live at home, with help from a main family caregiver. It looks at whether specialized support can be followed over time and whether it helps daily functioning.
BordeauxAges 18 years+ - NCT07235111Recruiting
Studying biomarkers for neurodegenerative diseases
This study is looking for people with neurodegenerative diseases (like Alzheimer's, Parkinson's, ALS) to help researchers find new markers in the body that could help understand these conditions better and possibly lead to better treatments.
Genoa, GenoaAges 18 years+ - NCT07449117Recruiting
Brain stimulation for language in mild cognitive decline
This study tests a new type of gentle brain stimulation (called temporal interference) to see if it can improve language processing in people with mild cognitive impairment. The stimulation uses electrodes placed on the head and is done while you are in an MRI scanner.
Brno, South MoravianAges 60–80 - NCT07284719Recruiting
Focused Ultrasound for Parkinson's Tremor
This trial tests a non-invasive treatment called MR-guided focused ultrasound (MRgFUS) to reduce severe tremor in Parkinson's disease. It uses sound waves to target the brain area causing the shaking, without surgery.
AarhusAges 50–80 - NCT06562569Recruiting
Non-invasive vagus nerve stimulation for Parkinson's gait issues
This study tests a non-invasive vagus nerve stimulation device to see if it can improve walking and reduce freezing of gait in people with Parkinson's disease. It is done at VA hospitals and involves wearing a device on the neck during walking tasks.
Hines, IllinoisAges 50–88 - NCT04373317RecruitingPhase 4
Comparing two medicines for hallucinations in Parkinson's disease
This study compares two drugs, pimavanserin and quetiapine, to see which works better for hallucinations or delusions caused by Parkinson's disease. The goal is to help patients manage these symptoms more effectively.
Tucson, ArizonaAges 40 years+ - NCT03217396Recruiting
Study blood and MRI markers in people with multiple sclerosis
This study looks for signs of “synapse damage” in multiple sclerosis using blood tests and brain imaging (MRI). The goal is to find biomarkers that may help better understand MS and how it changes over time.

Study to track Parkinson’s signs using imaging, spinal fluid, and genes
This study is building a large, detailed group of people—some with Parkinson’s and some at higher risk—to understand early changes over time. It uses brain imaging (DaTscan SPECT), sometimes spinal fluid tests (lumbar puncture), and genetic information to help researchers better measure disease and develop future treatments.

Common questions
- Are there clinical trials for parkinson’s disease?
- Yes. Clin2 currently lists 723 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.
