What is the Origin of Functional Health Span Extension?

This term is a cornerstone of geroscience and preventative medicine, evolving from the traditional focus on life span (longevity) to the more meaningful metric of health span (vitality). The concept emphasizes "functional" capacity, highlighting the importance of preserving mobility, cognitive acuity, and hormonal balance as markers of successful aging. It shifts the clinical paradigm from disease management to proactive vitality enhancement.

What is the Mechanism of Functional Health Span Extension?

Extension is achieved by modulating the molecular hallmarks of aging, which include mitigating chronic inflammation, improving cellular senescence clearance, and maintaining telomere integrity. Hormonal health plays a critical role, as optimal levels of growth hormone, DHEA, and sex steroids support muscle protein synthesis, bone density, and neuroprotection, directly underpinning functional reserve. Lifestyle and pharmacological interventions are deployed to support these endogenous repair and maintenance pathways.

Functional Health Span Extension

Meaning

Functional health span extension is the clinical objective of increasing the period of life during which an individual remains in good health, maintaining robust physical, cognitive, and emotional function, free from chronic debilitating disease. This goal focuses on extending the quality of life, not merely the duration of life, by preserving systemic physiological reserve and autonomy. Achieving this extension requires a comprehensive strategy targeting the fundamental biological drivers of aging and senescence.
