My dm was diagnosed with vascular dementia and alzheimers a few months ago. We have known for the past couple of years but has taken ages to get a diagnosis. I live a couple of hours away but have some siblings who live in the same town as her thankfully as she has been on her own since df died in 2020. The other evening, she was at my db's for dinner when she was sick, so he stayed with her that night to make sure she was okay. In the middle of the night he heard her up taking a shower and went to see she was okay and she was confused and talked about the house falling down and she was dirty. He got her back to bed and settled and she obviously had had a bad dream. I am staying with her tonight and woke up as I heard her in the bathroom. She had left the lights on and the hot tap running and was back in bed, but was confused and had her pyjamas off. She said she had a bad dream and couldn't get her clothes off. I am staying with her tomorrow night as well so will see if there is a repeat but wondering if this is going to be a regular occurrence? Worried now about whether she is safe to be left at home at night on her own. She seems okay during the day and still able to keep herself and the house tidy. Could it be the dementia medication giving her the bad dreams? She has only been on them since May and the dose was increased a couple of weeks ago. Any advice or similar experiences would be appreciated.
