Book excerpt: This is a comprehensive yet practical guide to the care and management of patients with dementia from the time of diagnosis to the end of life. It is intended for the increasing number of physicians, nurses, psychologists, social workers, rehabilitation therapists, and long-term care givers responsible for the care of individuals with dementia. For the Second Edition, the authors have added a chapter on mild cognitive impairment. The sections that received the most extensive revision or expansion include those on drug therapy; the pathophysiology of several causes of dementia; psychiatric symptoms of dementia and their treatment (especially drug treatment); and dementia in special environments (especially assisted living and nursing homes).
