Parkinson's and immunosuppressant drugs study
This study looks at how taking immunosuppressive medicines affects the course of Parkinson's disease. It compares people with Parkinson's who have been on these drugs for over a year to those who have never taken them regularly.
WarsawAges Any age - NCT06817772Enrolling by invitation
Digital markers for movement in Parkinson's disease
This trial uses smartphone sensors to track movement in people with early-to-mild Parkinson's disease. It aims to find digital markers that help doctors better monitor symptoms and adjust treatments.
Madrid, MadridAges 30–80 - NCT06692920Recruiting
Parkinson's brain signals study during DBS surgery
This study looks at brain signals in people with Parkinson's who are already scheduled for Deep Brain Stimulation (DBS) surgery. The goal is to better understand how certain brain pathways work, which could lead to improved treatments.
Minneapolis, MinnesotaAges 21–75 - NCT06630702Recruiting
Spinal cord stimulation for freezing gait in advanced Parkinson's
This trial tests if a small device placed near your spine (spinal cord stimulation) can help improve freezing of gait in people with advanced Parkinson's whose medicines aren't enough. It also aims to reduce leg pain if you have it.
Hsinchu, Hsinchu CityAges 40–85 - NCT06518824Recruiting
Theta brain stimulation to boost thinking in Parkinson's
This study tests whether a special pattern of deep brain stimulation (called theta bursts) can improve thinking and memory in people with Parkinson's disease. It's for patients who already have a DBS device in their brain that is at least 3 months old.
Vancouver, British ColumbiaAges 18–80 - NCT06506058Recruiting
Study on balance and brain in Parkinson's freezing of gait
This study looks at how the balance system and brain work together to cause freezing of gait in Parkinson's disease. By understanding these factors, researchers hope to find better ways to help people walk more steadily.
Minneapolis, MinnesotaAges 21–80 - NCT06464029Recruiting
Balance and walking study in Parkinson's disease
This study looks at balance problems in people with Parkinson's disease. It uses simple tests to understand what causes trouble with standing and walking, which may help find better treatments.
Minneapolis, MinnesotaAges 45–80 - NCT06386497Recruiting
Bed for better sleep in Parkinson's disease
This study tests a special bed (Somnomat Casa) to help improve sleep in people with Parkinson's disease. It looks at whether the bed is comfortable and acceptable to use.
BernAges 18–85 - NCT06234995RecruitingPhase 4
Brain activity and movement control in Parkinson's
This study looks at how the brain controls movement in people with Parkinson's disease, including those who have had deep brain stimulation (DBS) surgery. It involves recording brain activity and may help doctors understand how to improve treatment.
Atlanta, GeorgiaAges 45–75 - NCT06207136Recruiting
Diet and Gut Bacteria in Parkinson's
This study looks at how diet and the bacteria in your gut (microbiome) affect Parkinson's symptoms. You'll work with a coach and take cooking classes to see if changing what you eat can help you feel better.
Vancouver, British ColumbiaAges 40–80 - NCT06104397Enrolling by invitation
Exercise strategies for Parkinson's disease
This study compares different exercise plans to see which works best for people with Parkinson's. You will use an activity tracker and a phone app to track your progress.
Chicago, IllinoisAges 18–89 - NCT05960331Recruiting
Study how choice affects learning movement in Parkinson’s
This study looks at whether having more control or “autonomy” helps you learn new movement tasks. It may help researchers find ways to improve physical therapy training for people with Parkinson’s.

Brain training game to improve balance in Parkinson's
This trial tests a brain-training game designed to improve balance in people with Parkinson's disease. You may be eligible if you have mild to moderate Parkinson's, have had a fall and freezing episodes in the past year, and are not very active.
LeicesterAges Any age - 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.
Los Angeles, CaliforniaAges 18 years+ - NCT05779475Enrolling by invitation
Study of people with moderate Parkinson’s disease
This is an observational study, meaning it doesn’t test a new drug—researchers mainly follow people to better understand moderate Parkinson’s disease and who may be good candidates for future cell therapy. If you have moderate symptoms that aren’t well controlled with tablets, this study may help inform better future treatments.
Irvine, CaliforniaAges 50–68 - NCT05765110Recruiting
Tracking speech, movement, and thinking in Parkinson’s disease
This study looks at how people with Parkinson’s disease speak, move, and think to see whether these patterns can act like a “biomarker” (a measurable sign) of the disease. It also involves healthy volunteers to compare results.
