Both My nanna and my papa have dementia. Papa is pretty much in the final stages now. He has no clue who anyone is or what is going on. My nana isn't quite that far gone yet. The one thiing people often don't realise is how nasty these usually kind and gentle people can become. My nana is a right piece of work at the moment. She it cruel and derogatory in almost everything she says about anyone. Even when she is complimenting it is a backhanded kind. It can make it very hard on those people trying to care for her. You need to grow thick skin and remember that it is the desease not them who is talking. My grandparents have always enjoyed a drink, but began to drink alot more when dementia started. Partly as a coping mechanism I think, but also because they would simply forget that that had already had a drink. So as the desease progressed they both became alcholics, which in turn made the desease progress faster.
