Abstract:As the population ages rapidly, the number of the elderly individuals with frailty and dementia also increases, which has a profound impact on their clinical outcomes. Current research on frailty is mainly focused on physical and physiological factors, and the association of frailty with cognitive, psychology, and society remains unclear. A comprehensive multidimensional and integrated assessment of frailty for individualized and integrated interventions is important to improve the quality of life of the elderly adults.
