“Senile Dementia”: A Changing Perspective

Abstract

To demonstrate how 'senile dementia emerged as an important psychiatric concept is not an easy task. Although the history of general psychiatry can be satisfactorily traced to the spirited endeavours of Hippocrates (460–375 B.C.), Celsus (circa 30 a.d.), Soranus the elder (circa 100 a.d.), and Aretaeus (circa 150 a.d.), the psychiatry of old age unfortunately lacks such a clear and well-defined genealogy. The term 'senile dementia’ itself seems to have been first used by Aretaeus, the physician of Cappadocia, but exactly how it had evolved and how it was differentiated, if at all, from normal senescence is not at all clear. Certainly modern psychiatry has inherited a wealth of graphic description of old age in general, and for a detailed account of the relevant ethnographic literature the reader is referred to the excellent article by Rosen (1961). From a scientific point of view, however, it is unfortunate that the spirit of enquiry and the descriptive contributions of the early writers seem to have been tempered more by the degree of optimism or pessimism with which they anticipated the intellectual and behavioural foibles of old age, than by a desire to explore and evaluate systematically its possible deviations.
