The Original Giants (1965) were coined by Bernard Isaacs as immobility, instability, incontinence, and impaired intellect/memory.
Two New Modern Giants have been updated to reflect contemporary geriatric medicine, shifting focus toward physiological decline and metabolic vulnerability
These modern syndromes serve as major harbingers for adverse health outcomes, including falls, hip fractures, increased hospitalization rates, institutionalization, and higher overall mortality. Early identification using screening tools (such as the FRAIL or SARC-F scales) helps clinicians implement targeted interventions such as resistance exercise and nutritional support.
