[The relations between aging and disease].

In a survey concerning the relations between ageing and disease the peculiarities of a nosology referred to old age are discussed. From the point of view of clinical gerontology the compilation contains problems of the determination of the normal value, the demarcation of orthological and pathological changes caused by ageing, of the morbidity, the symptomatology and the therapy. The paper sketches the modern state of knowledge and refers to the continuation of clinical gerontology, the special task of which should last not least consist of the formation of a diagnostic and therapeutic standard adequate to age.
