Hebrew SeniorLife created the word ReAge to reflect the breadth and depth of services we offer: providing world-class health care; building innovative senior communities; funding groundbreaking research; and teaching future generations of geriatricians.

ReAge, a combination of “redefine” and “aging,” means to question everything about the aging process. Through ReAging, we are challenging conventions in order to create and implement new standard-of-care approaches that will positively impact the lives of older adults.

What is Gerontology?

Do you know the difference between gerontology and geriatrics? Or understand what a gerontologist does versus a geriatric specialist? While both strive to improve life for seniors, and are clearly related, there is a difference between the two disciplines.

Gerontology is the study of the aging process including investigation of the physical, mental, and social changes that affect people as they age. Geriatrics is a branch of medicine that focuses on health promotion, as well as the treatment of disease and disability later in life.

At Hebrew SeniorLife, geriatric specialists are devoted to preserving or improving physical and mental function as well as curing age-related diseases. The goal of geriatric medicine is to allow elderly people to remain as independent as possible for as long as possible. The geriatrician is not exclusively a heart or kidney doctor, but a specialist in syndromes that affect elderly patients. For example, geriatricians are experts in multiple systems and diseases such as Alzheimer’s, Parkinson’s Disease, Prostate enlargement, osteoporosis, and hypertension.

While geriatric specialists are medical doctors, gerontologists are researchers and practitioners from diverse fields, such as nursing, social work, psychology, or physical and occupational therapy. Through various practices, these professionals strive to address senior health issues and improve the quality of life and care of seniors.

Hebrew SeniorLife has always been a leader in gerontology with research professionals at the Institute for Aging Research conducting rigorous medical and social studies aimed at developing strategies that maximize strength, vigor and physical well-being, as well as preserve cognitive and functional independence for adults as they age.

Aging can be a challenging stage of life, but both geriatric specialists and gerontologists work to improve senior health issues and ensure that the process of aging can be comfortable, productive, and gratifying.
