| Riassunto: | Unsuccessful ageing has long been recognised but poorly defined, encompassing overlapping notions of vulnerability, decline and disability. Frailty offered one way of describing this state, yet its identification often relied largely on clinical intuition rather than reproducible criteria. As Justice Potter Stewart famously remarked in another context, it was something ‘one knows when one sees it.’ This changed with the phenotypic definition introduced by Fried et al. in 2001 [1], which transformed frailty into an operational construct and enabled systematic study of its causes and consequences. In the years that followed, this frailty phenotype was shown to be clinically meaningful across diverse populations. Longitudinal studies demonstrated that individuals classified as frail were at increased risk of falls,hospitalisation, disability and mortality, even after accounting for age and comorbidity [2]. Importantly, the phenotype proved not only predictive but also practical, enabling frailty to be identified consistently in epidemiological studies and clinical cohorts. This body of work established frailty as a robust marker of vulnerability and reserve, cementing its role as a cornerstone of geriatric assessment. |
