Strong and specific associations between cardiovascular risk factors and brain white matter micro- and macro-structure in health ageing

This study examines the associations between cardiovascular risk factors and white matter structure in aging, finding that systolic blood pressure, diastolic blood pressure, and heart rate independently impact white matter health.

Physical activity predicts population-level age-related differences in frontal white matter

The paper shows that physical activity preserves frontal white matter integrity and reduces age-related slowing in a population-based sample.
