People with memory loss due to dementia often do not remember what is about to happen during their day. They may not recognize where they are, whom they are with, nor, when it is in time. As a result of their changing understanding of the world around them, they may develop persistent high anxiety. Learning how to interact with them to keep them feeling secure and calm is very beneficial to both people with dementia and their carers. This book provides a brief, easily understood, orientation to the causes and effects of dementia, assisted by carefully designed on-line search terms, which will lead the reader to explanatory illustrations. Reflective exercises are provided, in order to help the reader to build an empathetic understanding of the emotional context within which the person with dementia dwells. Fundamental interaction patterns are explained. Written by the author of "Thoughtful Dementia Care TM: Understanding the Dementia Experience" (2012).
