Abstract

Vascular cognitive decline is a prominent cause of late‐life cognitive impairment. Compared to Alzheimer’s disease(AD), there is a paucity of biomarkers for its diagnosis, stratification, and treatment monitoring. Cerebrovascular‐Reactivity(CVR) MRI measures small‐vessel dilation to vasoactive‐stimuli(e.g. CO2), and has been shown to be associated with cognitive impairment. However, previous CVR studies were based on Blood‐Oxygenation‐Level‐Dependent (BOLD) MRI signal, which reflects a complex interplay of many physiological parameters and thus presents interpretation challenges. We measured CVR using quantitative CBF‐imaging in older participants, and tested for associations with diagnosis (Healthy Control [HC] vs. mild‐cognitive‐impairment [MCI] vs. dementia) cognitive and physical function, amyloid and tau burden, and vascular risk.
