Gut check: could your microbiome predict a stroke?
NCT ID NCT05113043
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether an imbalance in gut bacteria is linked to stroke risk and recovery in young adults (ages 18-45). Researchers will analyze stool and blood samples from 60 stroke patients to find patterns that could help predict strokes earlier. The goal is to understand the gut-brain connection and identify new ways to prevent or treat stroke in younger people.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Young patients (18-45 years old) with ischemic or hemorrhagic stroke, who are admitted within 12 hours post-stroke are included. To avoid interfering factors, patients with existing prior neurological disease or known tumors, inflammatory bowel disease and other digestive system diseases, patients with serious life-threatening diseases or condition, patients under antibiotics, probiotics or prebiotic treatment within 3 months before stroke, and patients who deteriorate and die before collecting faecal samples are excluded. Clinical data are documented, including age, gender, types of stroke as evidenced by imaging examination and laboratory examination, etc.
