Fecal transplant for Parkinson's disease

This study tests whether a treatment called fecal microbiota transplantation (FMT) can help relieve constipation in people with Parkinson's disease. FMT uses healthy donor stool to improve gut bacteria, which may ease constipation and possibly improve Parkinson's symptoms.

This trial tests whether transplanting healthy gut bacteria from a donor can help reduce motor complications (like involuntary movements or on-off medication cycles) in people with Parkinson's disease who have had the condition for at least 5 years.

This trial studies whether fecal microbiota transplantation (a procedure that transfers gut bacteria) can improve symptoms in people with schizophrenia. It may help by changing the gut microbiome, which researchers think could affect brain and behavior symptoms.

This trial studies fecal microbiota transplantation (a stool-based treatment) to improve symptoms and safety in people with certain gut and immune conditions. It aims to see whether changing gut bacteria can help you feel better.

This study looks at the germs in your gut and certain chemicals they make, which may relate to Parkinson's disease. It compares people with Parkinson's to healthy people of similar age and body size to see if there are differences.

This trial studies whether fecal microbiota transplantation (FMT)—a medical procedure using stool from a screened donor to restore gut bacteria—can improve safety and outcomes for people with certain bowel, immune, and metabolic conditions. It may help if your symptoms are thought to be related to an unhealthy gut microbiome, though eligibility is broad and depends on specific safety factors.
