Exploring the Relationship Between Aging and Disease

Geroscience seeks to understand the molecular and cellular mechanisms responsible for aging as a major driver of common chronic conditions and diseases of older people. Read about the latest advances in the field, funding opportunities, upcoming seminars, and more.

About Geroscience

The geroscience hypothesis posits that since aging physiology plays a role in many – if not all – chronic diseases, addressing aging physiology will allow a reduction or delay in the appearance of multiple chronic diseases. Older adults are often afflicted by multiple comorbidities and while recent progress in addressing individual diseases has led to an increase in life expectancy, this has not always been accompanied by a parallel increase in healthspan, the portion of life spent in good health.

Aging itself is by far the greatest risk factor for most chronic diseases and disabilities which affect older adults. However, there is still a widespread perception that aging is immutable, and thus we often focus our research and clinical trials on curing specific diseases without addressing the contribution of aging physiology to the onset or severity of those diseases. But, in the last few decades we have made impressive progress in understanding the genetics, biology, and physiology of aging. Basic research in animal models has demonstrated the plasticity of lifespan. More importantly, we’ve been able to apply that knowledge to extend, in laboratory animals, not only the lifespan but also simultaneously increase animals' healthspan. That is, a slower rate of aging leads not only to a longer life, but also to a delay in the appearance and progression of most diseases of aging, as well as a slowing in age-related functional decline. What was thought to be disparate is now understood to be connected.

Geroscience Goals and Aims

Progress in aging research has made possible the emergence of the field of geroscience, the intersection between basic aging biology and disease. The aims of geroscience are to understand how aging enables diseases and to exploit that knowledge to slow the appearance and progression of age-related diseases and disabilities. In addition, it is well established that some diseases (and/or their treatments) can accelerate the loss of function and resilience normally associated with aging, thus leading to an early susceptibility to disease. Therefore, we need to recognize that the complex relationships between aging, loss of function and susceptibility to disease operate in both directions. By developing a deeper understanding of the major underlying cause of our age-related increase in vulnerability to most cancers, dementias, stroke, heart attacks, vascular disease, diabetes and many other chronic diseases, geroscience aims to improve overall health in our later years. In fact, one of the goals of geroscience includes a more holistic interpretation of older adult health, to include optimizing function and resilience, elements that affect quality of life even in the absence of overt disease. Interventions that slow the aging process would dramatically lower health care costs and have societal benefits that are unmatched by the cure of any single disease.

About GSIG

The “Geroscience Interest Group” (GSIG) was formed to enhance opportunities to explore the intersection between aging biology and the biology of diseases that are of interest to the various NIH Institutes and Centers. The GSIG is focused on basic biology, but with a longer view towards translation. By developing a collaborative framework that includes many NIH Institutes, we expect to identify major cross-cutting areas of research, to propose coordinated approaches, to identify hurdles, and to envision solutions. By working together, we expect to catalyze the development of new tools, models and paradigms that address the basic biological underpinnings of multiple diseases.

The GSIG includes participation by more than 20 NIH Institutes with an interest in the biological mechanisms that drive the appearance of multiple diseases of the elderly. The group includes both intramural and extramural scientists, and while some activities are performed in collaboration between the two groups, members in each branch have unique capabilities, and collaborations between the two branches are synergistic.
