Study how gut signals relate to brain aging and diseases
Part of Brain & nervous system, Immune system & allergy clinical trials.
This study looks at how the gut may influence the brain in normal aging and conditions like Alzheimer’s, Parkinson’s, and multiple sclerosis. It may help researchers understand new ways to measure or treat these brain changes over time.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are either ages 20–50 or 60–90
- Your thinking/memory tests fit one of the study groups (healthy, early Alzheimer’s, Parkinson’s, or relapsing-remitting MS)
- If you have Parkinson’s or MS and take study-related medicines, your dose has been stable for at least 6 months
- You must be able to have an MRI scan (no unsafe metal in your body, no pacemakers, and you’re not severely claustrophobic)
- You have not taken antibiotics in the last 3 months

This study uses powerful MRI scans to understand how the brain ages and why some people stay healthy while others develop neurological diseases like multiple sclerosis or Alzheimer's. It compares healthy volunteers to people with certain conditions, and all participants get a detailed brain MRI.
This study compares how the brain ages in people with multiple sclerosis (MS) and healthy volunteers. It uses MRI scans and other tests to understand brain aging better.
This study looks for signs of “synapse damage” in multiple sclerosis using blood tests and brain imaging (MRI). The goal is to find biomarkers that may help better understand MS and how it changes over time.
This study looks at how your gut's immune system relates to brain and nerve diseases. Researchers will collect samples during a colonoscopy to better understand connections between gut health and neurologic conditions like multiple sclerosis or Parkinson's disease.
This study uses a special MRI to look at brain stiffness in people with normal memory, mild memory problems, or Alzheimer's disease. The goal is to see if this scan can help tell the difference between these groups.
This study looks at how the bacteria in your gut might be connected to memory and thinking problems in Alzheimer's disease. It may help us understand if changes in the gut can affect brain health.
