Physical Frailty Syndrome – Aging –

“There is strong evidence that frailty is both prevented and ameliorated by physical activity, with or without a Mediterranean diet or increased protein intake,” noted Fried. “These model interventions to date are nonpharmacologic, behavioral ones, emphasizing the potential for prevention through a complex systems approach.” 

In the inaugural issue of the journal Nature Aging a research team led by aging expert Linda P. Fried, MD, MPH, dean of Columbia University Mailman School of Public Health, synthesizes converging evidence that the aging-related pathophysiology underpinning the clinical presentation of phenotypic frailty (termed as “physical frailty” here) is a state of lower functioning due to severe dysregulation of the complex dynamics in our bodies that maintains health and resilience. When severity passes a threshold, the clinical syndrome and its phenotype are diagnosable. This paper summarizes the evidence meeting criteria for physical frailty as a product of complex system dysregulation. This clinical syndrome is distinct from the cumulative-deficit-based frailty index of multimorbiditys. The paper is published online here.

Physical frailty is defined as a state of depleted reserves resulting in increased vulnerability to stressors that emerges during aging independently of any specific disease. It is clinically recognizable through the presence of three or more of five key clinical signs and symptoms: weakness, slow walking speed, low physical activity, exhaustion and unintentional weight loss.
