Beyond Usual Pace: Quick Walking Speed and Brain Health Outcomes in the Framingham Heart Study

INTRODUCTION: Stroke, dementia, and late-life depression share overlapping vascular pathophysiology, yet simple markers of shared neurological vulnerability across these conditions remain limited. Most gait research has relied on usual walking speed (UWS) alone, leaving it unclear whether quick walking speed (QWS) and gait adaptability (QWS minus UWS), relate to these conditions in the same way. METHODS: We examined associations of UWS, QWS, and gait adaptability with executive function, verbal memory, depressive symptoms, and incident stroke and dementia in the Framingham Heart Study Offsprin
