He was admitted for a period of 'assessment' following weeks of not sleeping properly. I have since found out that this is referred to as 'sundowning' which affects some patients suffering from alzeimers. He is being given medication to help, but to no great success. I feel that I can care for him at home, in a quieter, calmer environment than he is in currently. I am perfectly capable of giving my husband the required medication at home, possibly with regular visits from a community support nurse.
