Three core contents of geriatrics

Geriatrics covers a wide range, including basic medicine, clinical medicine, epidemiology, preventive medicine (including medical care) and social medicine. ? The basic medicine for the elderly mainly studies the aging changes of organs and systems such as tissues, physiological functions, biochemical immunity, etc. of the elderly, and explores the aging mechanism and methods to delay aging.

Geriatric clinical medicine mainly studies the etiology, pathology and clinical characteristics of common and frequently-occurring diseases in the elderly, and seeks effective diagnosis, treatment and prevention methods. These include the care and rehabilitation of the elderly. Through investigation, gerontology analyzes the health status, the distribution of common diseases and the causes of death of the elderly, and studies the effects of heredity, environment, life, health, psychology and other factors on the aging and diseases of the elderly, providing scientific basis for disease prevention and health care of the elderly. These include investigation and research in longevity areas.

Geriatric preventive medicine studies how to prevent senile diseases; Health care for the elderly is to try to maintain the normal functions of various organs of the elderly and maintain good health through various efforts. The two are closely related, and the key point is to study anti-aging measures and popularize health knowledge. Even if it cannot be cured, efforts should be made to reduce the disability rate of existing diseases. Many senile diseases are inherited from illness in middle age, and it is very rare for a sick middle-aged person to have a healthy old age. Therefore, both preventive medicine and health care research for the elderly should involve disease prevention and health care for middle-aged people.

Geriatric social medicine is a discipline developed in recent years. It discusses gerontology from a social perspective, studies the influence of environment on the health of the elderly according to scientific methods and achievements such as management, statistics, epidemiology and sociology, and also involves various health care and welfare undertakings for the elderly.
