I am 85 and MW is 84 and is in an advanced state of Alxheimers. For four or five years MW was very abusive, both verbally and physically. Eighteen months ago she was put on memantine and resperidone and the aggression has mostly disappeared but still surfaces when I ask her to do something that she does not want to do. This is particularly so in the evening when the carer comes to give her the medication and I ask her to let the carer get her into her night clothes. This is at about 8.30pm. If she does not get in her nightwear she goes off to sleep and when I try to get her to bed at about 10.0pm she is fast asleep and it takes ages to get her into bed. MW is now bed wetting on a regular basis and I wonder what is the next stage as she refuses to admit that she has AZ. Any ideas?
