Correlation Between Intestinal Microecology Imbalance and Stroke in Young Adults

The relationship between the intestinal microecology and stroke has become a research hotspot in neurology field today. Maintaining the balance of the intestinal microbiota are expected to bring new breakthroughs for prevention and treatment of stroke. In recent years, stroke in young adults has an increasing incidence and a considerable socioeconomic impact because of high disability rate and health-care costs. So there is an urgent need to explore the role and mechanism of intestinal microecology imbalance in stroke, especially in the development and prognosis of stroke in young people. This study aims to use multi-omics technologies, including microbial diversity, metagenomics and metabonomics, to reveal the characteristics of intestinal flora in young stroke patients, identify biomarkers for predicting outcome after stroke and early detection of young people at high risk of stroke, and to further explore the role of gut-brain axis in the pathogenesis of stroke.
