Geriatrics is a branch of medicine. Through studying the mechanism of human cell aging, we can understand the changes in the structure and function of human organs and the law of the occurrence and development of geriatric diseases, and formulate comprehensive management strategies for geriatrics. In recent years, the clinical practice of evaluating and intervening in geriatric syndrome with comprehensive geriatric assessment technology for the elderly has strongly promoted the development of geriatrics. Through comprehensive assessment of the disease status, functional preservation, quality of life and social adaptation of the elderly, we will formulate a comprehensive management strategy with the ultimate goal of achieving healthy aging.
