Read our Parkinson Disease research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study invites people who participated in an earlier Parkinson's disease research project to come back about 7 years later for follow-up visits. Researchers will use special brain imaging scans to measure changes in nerve cell connections and will also test thinking and memory skills to see if there's a connection between brain changes and cognitive decline.
Parkinson's disease affects thinking and memory in some people as it progresses, but doctors don't fully understand how brain changes lead to these problems. This research aims to track these changes over many years to better understand the disease and potentially help develop better treatments.

You would return for clinic visits where researchers assess your movement, thinking, and memory through standard tests. You would also undergo brain imaging scans—including PET scans and an MRI—to measure nerve cell connections and other brain features. The entire evaluation would happen over your visit(s), building on the data collected from you years earlier in the previous study.
