Abstract:Post-stroke cognitive impairment (PSCI) is common in patients with stroke and it affects the quality of life and prognosis of these patients, which has attracted increasing attention to research on the risk factors for the condition. Gut microbiota and its metabolites, as one of the research hotspots in recent years, have been proved to be closely associated with the development and progression of central nervous system diseases, especially in patients with stroke. Some articles have shown that gut microbiota and its metabolites are closely associated with early cognitive function decline and PSCI. In this article, we review the mechanism of interaction of gut microbiota and its metabolites with stroke, changes in gut microbiota after stroke, and the effects of changes in gut microbiota and its metabolites on stroke and PSCI; we also investigate the potential value of choline, probiotics, and antibiotics in the prevention and treatment of PSCI, which sheds new light on the prevention and treatment of PSCI.
