This engaging book is based on personal experience. It gives those who suddenly find themselves in the role of carer basic guidance on the altogether different reality of this devastating mental deterioration. Of course, it is also valuable to other family members who may not be carers in the strict sense of the word, but are still affected emotionally. The author gives ample examples of how he learned to deal with his wife's disease, including the first signs of onset, sleeping disorder, incontinence, delusions, alienation, intimacy and, finally, death. It is not, however, a book of doom and gloom, it is full of humour, bringing a spark of relief to what is so often a dark and frightening subject.
