The Longitudinal Cohort of Cerebral Small Vessel Disease in Ruijin Hospital

21. července 2026 aktualizováno: Ruijin Hospital

The goal of this observational study is to learn about neuroimage and biomarkers in the cerebral small vessel disease. The main questions it aims to answer are:

How does neurovascular coupling change during the progression of CSVD?
How is the pattern/mapping of alterations in CSVD biomarkers? Participants will be observed and visit the research center annually to perform multi-modal MRI, PET, neuropsychological tests, and blood tests.

Detailní popis

This observational study recruits participants with cerebral small vessel disease (CSVD) from hospitals and community-based populations. Healthy volunteers will also be recruited as controls. Longitudinal follow-up of these participants will help clarify the significance of neuroimaging and biological biomarkers during the development and progression of CSVD.

The investigators aim to establish a longitudinal cohort covering the spectrum of CSVD and identify key biomarkers associated with disease progression and cognitive decline. All participants will undergo multimodal MRI, PET imaging (optional) with different tracers, and blood biomarker assessments. Using multimodal MRI, the investigators will investigate alterations in neurovascular coupling and their role in the pathophysiology of CSVD. In addition, PET imaging (optional) and blood biomarkers will be used to characterize the spatial and temporal patterns of disease-related biomarker changes. Furthermore, additional neuroimaging and digital biomarkers will be evaluated within the cohort to improve disease characterization and prognostic prediction.
