Abstract
INTRODUCTION
Arterial stiffness (carotid-femoral pulse wave velocity [cfPWV]) and plasma neurofilament light (NfL), markers of vascular and neuroaxonal aging, are linked to cognitive decline. Whether higher cfPWV amplifies the NfL–cognition relationship remains unclear.
METHODS
Cognitively unimpaired older adults (N = 570) were assessed using composite cognitive scores from confirmatory factor analysis. cfPWV was dichotomized at the median. Plasma NfL was quantified on a Single Moleculte Array-High Definition, model X (SIMOA-HD X).
RESULTS
Higher NfL correlated with poorer performance across all cognitive domains (p < 0.05), and higher cfPWV was linked to worse episodic memory, working memory, and processing speed (p < 0.05). NfL× cfPWV interactions were significant for episodic (β = 0.289, p = 0.048) and working memory (β = 0.287, p = 0.025), with stronger NfL–cognition associations in the higher cfPWV group (episodic memory: β = -0.324, p < 0.01; working memory: β = -0.343, p < 0.01).
DISCUSSION
Greater cfPWV amplified the association between NfL-related axonal degeneration and cognitive decline.
