Autosomal dominant Parkinson disease 8

This study tests a noninvasive technique called temporal interference stimulation (TIS) to see if it can improve motor symptoms in people with Parkinson's disease and related conditions. Participants receive both active and sham stimulation in a random order, with each session la…

This study tests an experimental drug called BIIB122 in 50 people who have a specific genetic form of Parkinson's disease (LRRK2-PD). The main goal is to check the drug's safety and how it affects certain markers in the blood and urine over 12 weeks. Participants are randomly ass…

This study tests whether a special heart scan using a radioactive drug called 123I-MIBG can help identify Lewy body disease, a type of dementia that also affects movement and sleep. Researchers will compare scan results with clinical diagnoses in 50 people who have conditions lik…

This study tests a new PET imaging technique that uses 10 to 100 times less radiation than standard scans. Researchers will inject 200 healthy volunteers and patients with a radioactive tracer and use a high-sensitivity scanner to see if image quality remains good enough for dete…

This study aims to identify biomarkers—biological clues in the body—that can help distinguish between Parkinson's disease and similar conditions like progressive supranuclear palsy and multiple system atrophy. Researchers will follow people with early-stage parkinsonism and healt…
