Hi, my 81 year old mam does a great job of caring for my 84 year old dad who has Alzheimer's. They live in the same bungalow they had lived in for over 60 years. One of the things mam has to deal with is dad's inability to hit the pot when going to the toilet, anytime day or night. Mam has put towels around the toilet which she has to wash every day. Is this common amongst men with dementia? Mam tells me she shouts at my dad when it happens during the night, especially when he has sometimes taken to urinating in the living room, assuming he thinks he is at the toilet. I understand mam's frustration in the middle of the night but would it be better if she could stop herself from shouting and instead try cajoling dad to go to the bathroom? Or does it not matter? I worry that dad will just remember being shouted at. The other day he told my brother my mam is nasty. Is this all just past of the dementia? Mam looks after him so well and it's just very sad to see.
