Geroscience
Definition
Geroscience is an interdisciplinary field that studies how the biology of ageing drives multiple chronic diseases, emphasizing shared mechanisms such as inflammation, epigenetic change, and cellular senescence rather than treating each disease as completely separate. [1]
Why It Matters in Ageing Research
The geroscience hypothesis holds that ageing biology is a primary risk factor for multimorbidity, so interventions that modify ageing processes could delay or attenuate cardiovascular disease, cancer, and neurodegeneration in parallel, improving healthspan more efficiently than treating each condition in isolation. [2]
Common Confusion
- Geroscience is narrower than gerontology, which covers broader biological, psychological, social, and policy aspects of ageing.
- Geroscience is not the same as geriatrics, which focuses on the clinical care of older adults.
- Geroscience is a research framework, not a single intervention or treatment strategy.
