Ageing and dementia are closely related conditions. Increasing age of the general population causes increasing incidence of dementing disorders in later life, although cognitive impairment is not necessarily a consequence of advancing age. The book presents the papers of the International Symposium on Ageing and Dementia, October 17???19, 1997 in Graz, where internationally renowned experts in the field of ageing and dementia gave an overview of the current knowledge about the epidemiology, pathomorphology, clinical diagnosis and course of brain ageing processes and related dementing disorders, biochemical markers and imaging procedures for the diagnosis of Alzheimer??'s disease and current approaches to a successful treatment of dementia.
