My husband of almost 58 years has had diagnosed Alzheimer’s for about 4 years but began many years before. My family and friends were in denial for most of that time. Up until just before Christmas we led a relatively busy life but he had a water infection and had to go into hospital for two weeks. This was the first time he had aver been in hospital and indeed apart from the Alzheimer’s he has never been ill. He started to be difficult early evenings and saying he couldn’t sleep keeping me awake. I now have medication to help with the sleeping. It is what I am told is ‘sundowning’ that is troubling me now. He keeps saying he wants to go for a walk and is quite adamant that he must. He is a big man and although not violent his anger does concern me. How do people manage behaviour such as this?
