Research progress on issues concerning the definition of cognitive frailty
Since the first operational definition of cognitive frailty was proposed by the expert consensus group of the International Academy of Nutrition and Aging and the International Association of Gerontology and Geriatrics in 2013,frailty and neurocognitive assessment has become the standard diagnostic tool.Since then,the reported prevalence in the literature for cognitive frailty in community-dwelling elderly people vary by dozens of times,as a result of different scales and diagnostic cut-off points,seriously affecting health decision-making.This article reviewed the current literature with a focus on the re-recognition of the clinical significance of cognitive frailty,the limitations of existing assessment tools for diagnosis,and possible solutions in the future.
