5‐Year Associations among Cerebral Arterial Pulsatility, Perivascular Space Dilation, and White Matter Lesions

Abstract

In healthy older adults, indicators of SVD are related in a lead-lag fashion, in which the expression of WML and PVS precedes increases in cerebral arterial PI. Hence, we propose that elevated PI is a relatively late manifestation, rather than a risk factor, for cerebral SVD. ANN NEUROL 2022;92:871-881.
