Matrix-metalloproteinases are associated with white matter damage in older adults

**Introduction:** Matrix metalloproteinases (MMPs) regulate extracellular matrix remodeling and blood-brain barrier permeability, but associations with white matter integrity are unknown. This study relates cerebrospinal fluid (CSF) biomarkers of …

Elevated aortic pulse wave velocity relates to longitudinal grey and white matter changes

**Objective:** To determine whether baseline aortic stiffness, measured by pulse wave velocity (PWV), relates to longitudinal cerebral grey or white matter changes among older adults given aortic stiffness. **Methods:** Vanderbilt Memory and Aging …

Axonal injury partially mediates associations between increased left ventricular mass index and white matter damage

**Background and Purpose:** Left ventricular (LV) mass index is a marker of subclinical LV wall remodeling that relates to white matter damage in aging, but the molecular pathways underlying this association are unknown. This study assessed if LV …

Elevated aortic pulse wave velocity relates to longitudinal grey and white matter changes

**Objective:** To determine whether baseline aortic stiffness, measured by pulse wave velocity (PWV), relates to longitudinal cerebral grey or white matter changes among older adults given aortic stiffness. **Methods:** Vanderbilt Memory and Aging …

Lower cerebral oxygen utilization is associated with Alzheimer's disease-related neurodegeneration and poorer cognitive performance among apolipoprotein E ε4 carriers

Oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2) are markers of oxygen homeostasis that may offer insights into abnormal changes in brain aging. The present study cross-sectionally related OEF and CMRO2 to cognitive …

Subclinical compromise in cardiac strain relates to smaller cerebral grey matter volumes in older adults

**Background:** Global longitudinal strain (GLS) is a sensitive measure of regional myocardial function that is associated with cognition in older adults. This study examined if compromised GLS related to structural brain changes among aging adults …
