Our Mum, who is about 5 years into AD, lives at home with my younger brother. She attends day centres 5 days per week, which is brilliant for her and enables my brother to continue working full-time. A morning carer comes in to shower and dress her as personal care is now beyond her abilities. She is collected and driven home by transport attached to the day centre. We are now experiencing frequent occasions where she soils herself during the trip there, or whilst there and is resisting all attempts by the staff to clean her up. The day centre today phoned my brother and asked if I could possibly go down and sort her out as they "wouldn't like her to stop coming". He said it wasn't an option and neither could he go down and do it but would be quite happy to speak to Mum over the phone and suggest she co-operates. They are in a difficult position as she becomes aggressive/defensive and will shout, scream and lash out. Today and yesterday she actually went to the toilet before leaving so had help to clean up. It isn't diarrhoea, she has a healthy appetite and her diet is good (she is also Type 2 diabetes, medicated, and underweight but GP happy with it). She uses incontinence wear all the time now - she isn't incontinent as such, it's more that she doesn't know how to use the toilet any more. Even if we take her, she will stand in front of it and not know what to do or how to do it. Any suggestions please?
