Frailty index and phenotype frailty score: Sex- and age-related differences in 5XFAD transgenic mouse model of Alzheimer’s disease

Alzheimer’s disease patients (AD), as well as AD transgenic mice, are characterized by increased frailty. Furthermore, the assessment of frailty status represents a feasible approach for detecting individuals prone to develop more severe form of AD and for measuring the outcome of existing and putative AD therapeutics. The 5xFAD mouse is one of the widely used transgenic animal models of AD, but frailty in this model is scantly investigated. We...
