Learning To Speak Alzheimer's

As part of my research I've been reading 'Learning To Speak Alzheimer's' by Joanne Koening Coste. Although a lot of the advice is only relevant for those living in America some things she mentions are quite interesting, but the most interesting thing for me has been the reaction I get from other people when they see me reading it. People I have worked with and known for years are suddenly opening up to me about their parents or grandparents, it appears many of us have unspoken worries about relatives suffering from Dementia.
