My Mother has vascular dementia. Her demeanor ranges from sensible and considerate to being very angry and /or distressed as she doesn't know what's going on...or feels that she is being made to do what she doesn't want to do (which is sometimes what she had said a little earlier that she wanted). My mother is 94 and is short of energy; her mobility is limited. My sister lives with her most of the time. My sister has M.E which she manages pretty well but needs rest. I am there about a day and a half a week; sometimes more. My mother is very attached to my sister and is often quite nasty to me - though it passes quickly. A problem which has got much worse recently is that she is becoming very agitated if she hasn't something specific to do; she is no longer interested in reading the paper (though does listen to the radio) By about 8.00 am she is beginning to demand that my sister do something with her - but it is REALLY hard to think up things to do all day. They (or we) do go out somewhere virtually every day. We haven't been able to find a suitable day-centre - too noisy (she is very sensitive to noise) / too airless (she has heart failure) etc....My sister is looking for people who might come in. Should we ask for some sort of sedative to be added to her cocktail of drugs - could that be good for her? Or would that be unethical?
