For the Old Age, the old health and disease are not a future problem any more but present one. In many developed countries they try to make a many-sided research about the old health, senility disease. But in spite of these efforts, we did not make out the features of the old health and senility exactly, so produced a little. I think of the Oriental approach as a appropriate, synthetic view which can develop the new opportunity of solution to the old health and senility. Through the comparisons, contrasts and considerations between the Oriental-Western medicine about the old health and senility, I have investigated the medical course and I came to the conclusion as follows; 1. Both -the Oriental and the Western- define that senility is a inevitable phenomenon in any creature and is the natural phenomenon that weaken the function of the internal organs little by little in the body. So after we classify it into physiological, pathological aging, we research it. 2. In the Western medicine, they have made progress about the cause of senility but their researches are analytic, fragmental and unessential. Considering the general characteristics that senility is occurred in all creatures, the synthetic viewpoint of the Oriental medicine is more desirable. 3. In classifying the old disease the Western medicine makes a list analytically but only apply clinical field established to the old, while the Oriental medicine don't classify specially and apply the established symptom name. When we consider the traits of the disease of the old, functions and activities-centered viewpoint, that is to say, point of view of the Oriental medicine, are more useful than disease-centered. 4. In treating of the old disease, the Western medicine is limited to the popular method, while the Oriental medicine approach represent the various method based on variable of vital essence and energy. the Oriental medicine, however, has defects that haven't developed the technique and biomarker which can measure the function of creature. But I am sure that analytical research of the Western medicine have scientific advantages. 5. the Oriental-Western medical considerations on the old health and senility have a lot of parts which cooperated each other and will be a clue that can solve the mystery of lives.
