[Epidemiological aspects of morbidity in the elderly].

The spectrum of morbidity in older age is dominated by chronic diseases. Higher age is associated with functional difficulties, limitations, and disability. However, inter- and intraindividual variability is wide. Sequela of chronic diseases are crucial to the development of dependency and the use of health care. They are cost intensive. The number of very old people will particularly increase according to estimations of future demographic changes in Germany. It can, thus, be assumed that the need for geriatric care, specific prevention and rehabilitation will not decrease soon.
