St Louis, MissouriAges 50 years+ - NCT07176286RecruitingPhase 2
PET scan study for diagnosing Lewy body dementia
This trial is testing a special PET scan that uses a radioactive tracer (18F-mFBG) to see how much it is taken up by the heart. The goal is to help tell Lewy body disease (Parkinson's or Lewy body dementia) apart from other brain disorders.
Houston, TexasAges 18 years+ - NCT06949865Recruiting
AI-enhanced levodopa challenge test for parkinsonism
This study uses artificial intelligence (AI) to improve a standard test for parkinsonism called the levodopa challenge test. It may help doctors better understand how your movement symptoms respond to levodopa, a common Parkinson's medication.
BeijingAges 50–75 - NCT07154511RecruitingPhase 1/Phase 2
Tributyrin for Parkinson's with memory problems
This trial tests a supplement called tributyrin to see if it can help with thinking and memory problems in people with Parkinson's disease. You may be able to join if you have both Parkinson's and mild cognitive impairment or dementia.
Ann Arbor, MichiganAges 45 years+ - NCT07049341Enrolling by invitation
A pilot trial of the MemorEM device for neurological diseases
This trial tests a device called MemorEM to see how patients with neurological diseases like Alzheimer's or Parkinson's experience it. It aims to understand if the device is comfortable and easy to use.
Tampa, FloridaAges 45–100 - 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+ - 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 - NCT06147999Recruiting
Biophoton therapy for brain disorders
This trial tests a biophoton therapy, a light-based treatment, for people with brain disorders. It aims to see if this non-invasive approach can help improve symptoms.
Butler, PennsylvaniaAges 18 years+ - 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+ - NCT06529744Recruiting

Common questions
- Are there clinical trials for parkinson disease dementia?
- Yes. Clin2 currently lists 315 recruiting parkinson disease dementia 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 disease dementia 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 disease dementia 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.
