Cassino, FrosinoneAges 10 years+ - NCT02795052Recruiting
Stem cell treatment trial for nerve injury
This study tests whether bone-marrow stem cells can improve nerve function in people with nerve damage that usually doesn’t recover with current care. It also checks whether the treatment is safe and whether people can be followed over time with repeated nerve exams.
Westport, ConnecticutAges 18 years+ - NCT02194816Recruiting
Online survey study for people with Parkinson’s or Parkinsonism
This study looks at how changing certain factors over time relates to symptoms in Parkinson’s disease and related conditions. You may help researchers by completing longer online surveys every 6 months for 5 years.
Kenmore, WashingtonAges 19 years+ - NCT06120049RecruitingPhase 2/Phase 3
Comparing new PET scans for Parkinson's, MSA, Lewy body dementia, and Alzheimer's
This study tests if a new radioactive tracer called [18F]-MFBG can help doctors better distinguish between Parkinson's disease, multiple system atrophy (MSA), dementia with Lewy bodies, and Alzheimer's disease. It compares the new scan with two standard scans to see which is most accurate.
Ghent, GentAges 18–85 - NCT07592767RecruitingPhase 2
Resveratrol supplement for Parkinson's disease
This study tests whether a supplement called resveratrol (found naturally in grapes and berries) can help slow or improve Parkinson's disease symptoms. You'll take resveratrol pills or a placebo while researchers monitor your memory, movement, and overall health.
Washington D.C., District of ColumbiaAges 55–85 - NCT07218952Enrolling by invitation
Radiation therapy for Parkinson's disease
This trial tests if a targeted radiation therapy can help people with early-stage Parkinson's disease that affects only one side of the body. It aims to see if this treatment can slow down the disease and improve symptoms.
Rochester, MinnesotaAges 45–70 - NCT01799915Recruiting
Study of causes and progression of synuclein-related nerve conditions
This study follows people over time to better understand “synucleinopathies,” which are conditions that affect the nervous system as it develops and progresses. You may be asked to return for visits and report symptoms, especially those that happen when you stand up.
Boston, MassachusettsAges 18 years+ - NCT06875739Enrolling by invitation
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.
CagliariAges 60–85 - NCT07314190Enrolling by invitation
Blood tests for brain diseases and mental health conditions
This study looks at blood tests to help diagnose and track brain diseases (like Alzheimer's) or mental health conditions. It compares patients to healthy volunteers to find better ways to detect and monitor these illnesses.
