[Gerocomy -- gerontology -- geriatrics. The naming of a modern medical discipline].

300 years ago, the lawyer Theodosius Schöpffer coined the notion gerontology. On this occasion, this paper offers terms and corresponding concepts of gerontology which arose in the western tradition: 1. From the Graeco-Roman antiquity until 1750, gerocomy (the care for the elderly) was defined as a branch of medicine, but in practice almost did not exist. Basically, it provided instructions for a way of life in conformity with the physiological circumstances of elderly people. Its implementation was left to the patient. Furthermore, in the early modern times medical treatises dealt more frequently with diseases of the elderly and their therapy. The gerokomia succeeded in evolving a specific technical literature. Yet it failed to get institutionalized. 2. At the beginning of the 20th century, Ignaz Nascher interpreted geriatrics as a counterpart to pediatrics and opposed it to a clinical-pathological consideration of old age before 1900. He aimed at the exploration and treatment of old age as an autonomous physiological entity. Under the influence of the demographic transformation the institutionalization of geriatrics as a interdisciplinary branch within medicine could be realized relatively soon. 3. Around 1930, we experience the recreation of the notion gerontology, initially restricted to medical gerontology. However, with the integration of the non-medical sciences of old age the spectrum and the objectives changed. Today gerontology signifies on a international level a generic term or independent scientific discipline beside medicine. This evolution corresponds with the intentions pursued 300 years ago.
