This cohort study involves the dynamic collection of clinical information, including serum parameters , blood pressure variability, imaging data, and neuropsychological scales, in patients with cerebral small vessel disease (CSVD). The study aims to summarise the clinical and imaging characteristics of the CSVD population and identify novel CSVD risk factors. Additionally, this study intend to uncover the mechanisms underlying the clinical and imaging outcomes of CSVD. Furthermore, a multivariable prediction model for cognitive and mood disorders in patients with CSVD will be established.
