Gait speed is a robust marker of health in older adults and is associated with cognition, yet few studies have examined this in the oldest-old and if there are differences by cognitive domain. We examined the association between gait speed and cognition across three domains in individuals aged 90 + , considering differences by gender and device use. Then, 502 participants were included from the LifeAfter90 Study. Baseline gait...

Assessing whether grip strength is associated with cognitive decline and brain health could help identify a target to prevent or delay cognitive impairment. Therefore, we tested whether grip strength is associated with brain health as indicated by magnetic resonance imaging and domain specific cognitive decline. We also assessed whether grip strength was a cognitive resilience proxy using moderation tests. This study included...
