Renji Cerebral Small Vessel Disease Corhort Study

Study Overview
=================
Brief Summary
-----------------
We aim to make clear the impact with the mechanisms of variant pathological injuries on the outcomes of CSVD, to find independent imaging markers and establish prediction model of it.

Detailed Description
-----------------
A cohort of post stroke cerebral small vessel disease (CSVD) patients with different cognitive status are consecutively recruited in this study. Detailed full domain cognitive assessment and multi-modal MRI (including brain morphology , DTI indices, microbleed counts, brain volumes as well as brain network characters, etc.) are performed. Cognitive states(including attention-executive function, memory, language, visuo-spatial and global cognition with the transition to dementia) and the overall prognosis (cardiovascular events, stroke recurrence, death due to cardiovascular event and all cause death) are longitudinally followed up. The correlations between baseline and followed MRI parameters with the outcomes are analyzed in order to make clear the impact with the mechanisms of variant pathological injuries on the outcomes of CSVD, to find independent imaging markers and establish prediction model of it.
