About

This study is to find out the association between gut microbiota and moyamoya disease.

Full description

Moyamoya disease (MMD) is a rare cerebrovascular disorder, it is a major cause of stroke in children and young adults in Japan, Korea, and China, but its pathogenesis is not yet clear. Dysbiosis of gut microbiota may play a role in the pathological change of MMD. In this research, the investigators would perform metagenomic sequencing to find the characteristics of gut microbiota of MMD and to explore the correlations with metabolic, immune, and clinical symptoms. This research will not only help the understanding of the pathophysiology of MMD, but also may provide a reference for the selection of clinical treatment options.
