About

Diabetes mellitus (DM) plays an important role in the occurrence of the cerebral infarction (CI). Clinical studies have demonstrated that the CI patients with DM had a poor prognosis compared with those without DM. Previous magnetic resonance imaging (MRI) studies have shown that patients with DM had abnormalities in cerebral vessels, nerves and functions, similar with the findings in mice models. In this study, with multi-modal MRI technologies, investigators tend to observe structural and functional changes of the brain in both DM and non-DM CI patients and assess their neural rehabilitation using clinical scales in the following 6 months. Investigators also expect to find out dynamic changes of brain structure and function, to reveal the weights of factors including brain blood vessels, nerves and function remodeling related with stroke recovery, as well as the potential mechanism in CI patients with DM.
