My Mum has Alzheimer's. She has been in a care home in Devon for 3 years. I am an only child and live 200 miles away. The past 2 years I have had Mum to stay with me over Christmas. Her mobility has decreased in the past year and she is not well enough or mobile enough to come this year. In her mind all is well and "there is nothing wrong with me". She cannot understand why she can't come for Christmas. She gets verbally aggresive, which upsets me more as in a few minutes if the subject is changed she has forgotten about it! Please could I ask for advice on how to deal with this and what to say to Mum. I visit roughly every 2 months for 4 days at a time. For our trips out she has to be in a wheelchair now and can't be out for more than a couple of hours as she gets very tired or dizzy when she stands to go to the toilet. I don't want to move her nearer me as I feel while she knows where she is, 'in her beloved Devon', the move would be too disorientating for her. She still has a few friends that visit her and enjoys the church services at the home run by familiar people.
