Dementia is a growing problem, estimated to affect 24·3 million individuals worldwide, with 4·6 million new cases every year. Furthermore, many elderly individuals have other memory deficits and problems in cognitive functioning, and the cost of caring for these patients is high. There is a need for a systematic approach towards the effects of dementia and the practical problems of managing this disorder.
