介绍：Geriatrics is a field of medicine that deals with elderly people. The main focus of medical doctors in this field － geriatricians － is the overall health of elderly patients, and diagnosis and treatment of any illnesses they may encounter. Elderly-patient care often involves multiple health concerns at the same time, and patients may not respond to treatments in the same way as younger patients. Geriatricians are trained to deal with these unique situations. Social aspects involving elderly patients, such as home support, may also be evaluated by a geriatrician providing care.
