Ageing and dementia in developing countries — the work of the 10/66 Dementia Research Group

Abstract

Demographic ageing proceeds apace in all world regions (United Nations, 2003). The proportion of older people increases as mortality falls and life expectancy increases. Population growth slows as fertility declines to replacement levels. Latin America, China and India are experiencing unprecedentedly rapid demographic ageing (Figs 1 and 2).
