Performance Depreciation Curve

Meaning

Performance Depreciation Curve is a conceptual model illustrating the rate at which physiological and cognitive function declines over time, often accelerating with age or chronic lifestyle stressors. This curve serves as a clinical metric to track the progressive loss of systemic resilience, maximal capacity, and homeostatic reserve. The objective of longevity medicine is to flatten and shift this curve to the right, thereby extending the period of high-quality healthspan and delaying the onset of functional impairment.
