Gut immune changes in Lewy body disorders
Role of altered gut immune response in Lewy Body Disease
This project looks at whether changes in gut immune signals and gut bacteria are linked to Parkinson's disease, dementia with Lewy bodies, and people with early signs like REM sleep behavior disorder.

What this research studies
You would join a study that compares people with Parkinson's disease, dementia with Lewy bodies, and those with isolated REM sleep behavior disorder to healthy volunteers. The team will collect gut-related samples (for example stool and possibly colon biopsies), measure immune cells and antibodies, and analyze the gut microbiome and physiological signs. Researchers will combine these human data with laboratory models to explore how microbial and immune changes might contribute to brain disease. Findings will be used to connect gut changes with symptoms and to identify possible targets for future treatments.
Who could benefit from this research
Good fit: Ideal candidates are people diagnosed with Parkinson's disease or dementia with Lewy bodies, and people with isolated REM sleep behavior disorder, who can attend Stanford visits and provide gut samples.
Not a fit: People without Lewy body disorders or unrelated neurologic conditions, and those unwilling or unable to provide stool or colon samples, are unlikely to receive direct benefit from participation.
Why it matters
Potential benefit: If successful, this work could reveal gut-based markers or targets that help detect Lewy body disorders earlier or guide new treatments.
How similar studies have performed: Previous studies have suggested links between the gut microbiome, immune changes, and Parkinson's disease, but comprehensive human-to-lab mechanistic work like this remains relatively new.
