Understanding the Gut-Brain Connection in Lewy Body Conditions
Microbiome-gut-brain dysfunction in prodromal and symptomatic Lewy body diseases
This project explores how changes in gut bacteria might be connected to brain changes in people with early or active Lewy body conditions like Parkinson's Disease Dementia and Dementia with Lewy Bodies.

What this research studies
Lewy body conditions, including Parkinson's Disease Dementia and Dementia with Lewy Bodies, cause significant memory and thinking problems that are hard to treat. We believe that an imbalance in gut bacteria, specifically an increase in certain types, along with a leaky gut, might play a key role in these conditions. This project aims to see if these gut changes are present early on and if they are linked to brain degeneration and symptoms. We are particularly interested in people with REM Sleep Behavior Disorder, as this often signals the start of a Lewy body condition. By understanding these connections, we hope to uncover new ways to help people affected by these conditions.
Who could benefit from this research
Good fit: Ideal candidates for related future studies might include individuals with idiopathic REM Sleep Behavior Disorder or those in the early stages of Parkinson's Disease Dementia or Dementia with Lewy Bodies.
Not a fit: Patients whose conditions are not related to Lewy body diseases or gut microbiome imbalances may not directly benefit from this specific line of research.
Why it matters
Potential benefit: If successful, this work could reveal new targets for treatments that address the gut-brain connection in Lewy body conditions, potentially slowing progression or improving symptoms.
How similar studies have performed: While the specific link between gut bacteria and early Lewy body conditions is a novel area of focus for this project, increasing evidence suggests a perturbed gut microbiome may drive disease pathogenesis in these conditions.
