Concomitant impairments in physical, psychological and cognitive function are common in old age. Our previous work has elucidated that addressing these impairments and their interplay are critical to minimize fall risk and achieve healthy ageing. The overall research objective of our ongoing research in this area is to develop a clearer understanding of inter-related underlying mechanisms of the effects across the triad of physical (frailty, balance), psychological (fear of falling, mood), cognitive (executive function, MCI, dementia) and neural (white matter integrity) impairments on falls and healthy ageing.
