Special Issue: Dementia, Frailty and Aging

Welcome to this issue under Frontiers in Medicine which blends nicely with our research focuses of ageing brain (dementia) and frailty. This collection of 14 articles runs the gamut from insights in interface between cognition and physical domains, through to pertinent areas of caregiving and diagnosis in dementia, and evolving areas such as big data and microbes theory in brain ageing.
