Aging as the Master Driver of Chronic Disease
Geroscience research, notably the Hallmarks of Aging framework. · The Hallmarks of Aging (López-Otín et al., 2013) (2013)
Aging is the primary risk factor for most chronic diseases, meaning interventions that slow biological aging can simultaneously reduce the risk of multiple conditions.
Core Concepts
The Problem
Traditional medicine treats age-related diseases as separate entities, ignoring the shared underlying biology of aging.
The Claim
Targeting the aging process itself will be more effective than treating each disease individually.
Key Evidence
- •The observation that cancer, heart disease, and Alzheimer's all increase exponentially with chronological age.
- •Animal studies show that interventions like caloric restriction delay multiple age-related diseases.
- •Geroprotector compounds extend healthspan and delay onset of multiple conditions in model organisms.
Practical Implication
Healthcare strategies should prioritize gerotherapeutic interventions to compress morbidity and extend healthspan.
Nuance & Limits
Not all aging changes are reversible, and the definition of 'aging' is still debated; however, targeting underlying mechanisms shows promise.

Mitochondrial decline is a key hallmark of aging and a sub-mechanism linking aging to disease.
Chronic inflammation is both a hallmark and a consequence of aging, reinforcing disease progression.
Gaps
- ⚠ The specific causal pathways linking aging hallmarks to individual diseases need further elucidation.
