"Dementia represents a major public health challenge for the world with over 100 million people likely to be affected by 2050. A large body of professionals is active in diagnosing, treating, and caring for people with dementia, and research is expanding. Many of these specialists find it hard to keep up to date in all aspects of dementia. This book helps solve that problem. The new edition has been updated and revised to reflect recent advances in this fast-moving field."--Publisher.
