Abstract
The population in all over the world, also in Japan, is aging rapidly and nearly all countries will experience substantial growth in the size of the population over age 65 till the year 2050. Recent improvements in medicine and public health are now producing more rapid growth in the number of aged individuals. Growth of the aged population inevitably results in an increase in the number of cognitive disorders. Demented people will be more frequent in aged populations. But dementia is one of the disease, and differs from aging process.
Doctors, who diagnose and treat the demented people, need the knowledge of the disease, educate care-givers and cooperate with welfare work stuff. Adequate education and support for care-givers are quite important to lessen their burden. A primary care by the team approach can enhance the QOL for the patients and their families. So differential diagnosis and evaluation of each feature and daily life are quite important.
To conduct the medical service for the dementia, worthy of the national center, it is essential to form the functional group without regard to departments and occupations.
