Geriatric medicine focuses on health care of elderly people. Its objective is to boost health by preventing and treating diseases and disabilities in older adults. There is no age limit at which patients may be under the care of a geriatrician or geriatric physician, a physician who specializes in the care of elderly people. Rather, this decision is regulated by the individual patient's requirements, and the availability of a specialist.
It is significant to note the difference between geriatrics, the care of aged people, and gerontology, which is the study of the aging process itself. Geriatrics differs from traditional adult medicine because it focuses on the distinct needs of the elderly person.
