Brain Chemistry and Aging: Healthy and Parkinson's Study
Part of Brain & nervous system clinical trials.
This research uses brain imaging scans to study how a chemical messenger in the brain (called noradrenaline) changes as people age and in Parkinson's disease. The goal is to better understand how this brain system works and may help develop future treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be between 20–80 years old (or 40–80 if you have Parkinson's disease)
- Weigh between 40 kg and 100 kg (88–220 lbs)
- Have no history of serious head injury with loss of consciousness lasting more than 30 minutes
- Not be pregnant, nursing, or planning pregnancy during the study
- Be able to safely have MRI and PET scans (no pacemakers, metal implants, or claustrophobia)
- Not be taking certain medications that affect the brain or emotions in the past month

This study uses brain scans to understand how people with Parkinson's disease process social cues, like faces and emotions. It may help researchers learn more about how Parkinson's affects social thinking.
This study uses brain scans to understand Parkinson's disease. It compares people with Parkinson's to healthy volunteers to learn how the brain changes.
This study uses MRI scans to look at dopamine signals in the brain. The goal is to understand how Parkinson's affects these signals.
This research study examines how the brain's immune system changes in older adults with memory problems, Parkinson's disease, or normal aging. By understanding these changes, researchers hope to better understand neurodegeneration and develop new treatments.
This study looks at how brain activity relates to thinking and walking in people with Parkinson's disease. It may help understand the connections between these functions.
This study uses a special PET scan to look at inflammation in the brain of people with Parkinson's disease or those at risk for it. The goal is to better understand the disease and possibly find new ways to track its progression.
