The study investigated relationship between cerebral small vessel disease (CSVD) burden, cerebral blood flow (CBF) and cardiovascular risk in the aging brains with normal cognitive function at baseline and conducted telephone cognitive follow-up for nearly 8 years. The results showed that severe CSVD burden was significantly associated with higher cardiovascular risk scores and decreased CBF in multiple areas, with involvement of nearly all cortical brain areas. Subjects with severe CSVD burden were more likely to suffer from long-term cognitive decline. This suggests the capability of CSVD burden serving as an imaging marker of predicting cognitive decline.
