ClinConnect Summary
This clinical trial is exploring how Parkinson's disease affects the way people understand social cues, like facial expressions and body movements. Researchers believe that these social perception difficulties can impact the quality of life for individuals with Parkinson's, even in the early stages of the disease. The study aims to use advanced imaging techniques, such as functional MRI, to observe brain activity related to social perception and determine how certain medications might influence this process.
To participate in the trial, you need to be between 30 and 75 years old and have been diagnosed with Parkinson's disease for at least three years while receiving treatment with specific medications. Participants will undergo two stages: the first will involve testing the experimental tasks, and the second will focus on assessing brain activity during these tasks. It's important to note that participants need to meet certain health criteria, and those with specific conditions that might complicate MRI scans cannot join. If you're interested or think you might qualify, this study could provide valuable insights into how Parkinson's disease affects social interactions.
