Young-onset Parkinson disease
MONDO:0017279A form of Parkinson disease (PD) characterized by an age of onset between 21-45 years, rigidity, painful cramps followed by tremor, bradykinesia, dystonia, gait complaints and falls, and other non-motor symptoms. A slow disease progression and a more pronounced response to dopaminergic therapy are also observed in most YOPD forms.
Also known as: YOPD, early-onset Parkinson disease, early-onset Parkinson's disease

Parkinson's vaccine trial aims to slow disease progression
Disease control OngoingThis study tests a vaccine called ACI-7104.056 in 150 people with early-stage Parkinson's disease. The goal is to see if it is safe and helps the body fight a protein linked to Parkinson's. Participants must already be on stable low-dose levodopa. This is not a cure, but may help…

New PET scan could slash radiation by 100x
Diagnosis ENROLLING_BY_INVITATIONThis 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…

AI boosts brain scan accuracy in massive new trial
Diagnosis ENROLLING_BY_INVITATIONThis study tests whether an AI tool can help radiologists read brain CT and MRI scans more accurately and quickly. Researchers will compare how well doctors, AI alone, and doctors using AI together can spot abnormalities, urgent findings, and classify diseases. The goal is to red…

Scientists hunt for clues to diagnose Parkinson's earlier
Knowledge-focused OngoingThis 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…

300 volunteers help create medical image bank for science
Knowledge-focused OngoingThis study gathers MRI, CT, and ultrasound images from 300 adults—some healthy, some with kidney or brain disease—to build a collection for future not-for-profit research. No new treatments are being tested; the goal is to make medical images available to scientists for advancing…
