Asymptomatic Cerebral Small Vessel Disease: Insights from Population-Based Studies

Area of Science:

• Neurology
• Radiology
• Epidemiology

Background:

• Cerebral small vessel disease (CSVD) significantly impacts global morbidity and mortality.
• CSVD is often diagnosed late, missing its early, asymptomatic stages.
• The prevalence and implications of CSVD in healthy aging populations are not well understood.

Purpose of the Study:

• To investigate the etiology and significance of CSVD biomarkers in asymptomatic individuals.
• To explore risk factors contributing to the development and progression of CSVD markers.
• To characterize asymptomatic CSVD and review current screening and research avenues.

Main Methods:

• Semi-systematic review of population-based studies focusing on asymptomatic individuals.
• Analysis of neuroimaging markers: white matter hyperintensities, lacunes, microbleeds, etc.
• Examination of risk factors and associations from observational clinical studies.

Main Results:

• CSVD neuroimaging markers are frequently observed in presumed healthy elderly populations.
• Identified common risk factors and potential shared pathways underlying CSVD.
• Highlighted the need for further research into asymptomatic CSVD characterization and management.

Conclusions:

• Asymptomatic CSVD is prevalent and warrants further investigation.
• Understanding risk factors is crucial for early detection and intervention.
• Future research should focus on screening modalities and therapeutic strategies for asymptomatic CSVD.
