With aging, the ability to do daily activities (functional ability) declines to some degree in every person. Also, older people, on average, tend to have more disorders and disabilities than do younger people. But the changes that accompany aging are more than just changes in health. Social issues (such as living arrangements or type of work) influence an older person's risk and experience of illness.
Providing medical care to older people can be complicated. People often have many different health care practitioners at different locations. Travel and transportation issues become more difficult as people age. Assistance by a team of health care practitioners under the leadership of a primary care practitioner or a practitioner who specializes in the care of older people (such as a geriatrician) is the best way to deal with these complexities. However, this ideal solution is often difficult to achieve.
