Researchers want to understand why about 60-80% of people with Parkinson's disease experience chronic pain. This study uses a special type of brain imaging called PET scanning with a radioactive tracer called [18F]-MPPF to look at how the brain's serotonin system — which helps control pain signals — may be different in people with Parkinson's who have pain compared to those without pain.
Current treatments don't always work well for Parkinson's-related pain, and doctors don't fully understand why some patients experience it while others don't. This research could help identify what's happening in the brain and lead to better pain management strategies in the future.

You would visit the research center for brain imaging scans (MRI and PET scans) that help researchers visualize your brain's serotonin system. The scans are non-invasive and painless, though they do require you to lie still for periods of time. You'll be in one of two groups based on whether you experience Parkinson's-related pain or not, but both groups receive the same imaging procedures.
