I am 86 and MW is 85 and has Alzheimer's for over seven years. I am her sole carer and it is becoming moe and more difficult to cope although she is on medication which has calmed her down from the years when she was abusive, both verbally and physically. For the last few years she has been calmer and quite confused but still able to understand most basic things. Her toileting has been difficult as she will not use pads and constantly wets her pants and trousers. However in he last few days she has deteriorated quite a bit to such an extent that she is unable to understand if it is day or night and has great difficulty negotiating the stairs whereas before she was slow but quit steady. I am having her urine tested in case it is a uti but I would like to hear from anyone who has had a similar experience of this as I am worried if this is a serious change. Sorry about the length of the post but things are getting difficult.
