Read our Parkinson's Disease research guide →Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
Researchers want to understand how a protein called tau accumulates in the brains of people with Parkinson's disease using a special imaging scanner. This study will compare tau levels in people with different types of Parkinson's disease, people with related brain conditions, and healthy volunteers. The goal is to learn whether tau buildup might help doctors better understand and diagnose Parkinson's disease.
Tau protein is known to be involved in several brain diseases, but scientists don't yet fully understand how it relates to Parkinson's disease specifically. This imaging study could reveal new clues about what's happening in the brains of people with Parkinson's and help develop better ways to diagnose and monitor the disease.

Over two years, you will have brain imaging scans using a special PET camera to measure tau protein in your brain. If you are enrolled in the first year, you may have scans on two different imaging systems so researchers can compare them. You may also return at 12 months for a follow-up scan to see if tau levels change over time. The study will use information from your existing medical visits and records to reduce the number of trips you need to make.
