What is the Origin of Brain Aging Geroscience?

The term is a compound of "Brain Aging" and "Geroscience," where Geroscience itself emerged in the early 21st century as a distinct field of longevity research. "Geros" is derived from the Greek word gerōn, meaning old man, and "science" denotes systematic study. Its application to the brain acknowledges that neurodegeneration is largely a consequence of fundamental aging processes rather than isolated diseases.

What is the Mechanism of Brain Aging Geroscience?

The geroscience approach targets conserved molecular pathways implicated in both aging and brain health, including mitochondrial dysfunction, telomere attrition, and impaired proteostasis. By modulating these core aging mechanisms—for instance, through caloric restriction mimetics or senolytics—the rate of pathological change in the brain can theoretically be decelerated. The resulting neuroprotection is designed to preserve synaptic integrity and cognitive function across the lifespan.

Brain Aging Geroscience

Meaning

Brain Aging Geroscience represents an interdisciplinary field of study that focuses on the fundamental biological processes of aging as they specifically manifest in the central nervous system. The primary clinical objective is to understand how age-related changes, such as cellular senescence, chronic low-grade inflammation, and altered nutrient sensing, drive cognitive decline and neurodegenerative pathology. This research aims to develop interventions that target these aging hallmarks to extend brain healthspan.
