Hi
@Chelle 101 and welcome to Dementia Talking Point. This is a very friendly and supportive place.
Any accident or illness seems to progress dementia. I had some concerns about my mother by 2016 but they were greatly amplified after she caught a nasty virus that Easter. She did improve a little when she returned to full health, but her decline became more marked afterwards.
Does your mother have any help coming in at the moment? If she has funds you could arrange this without needing to go through social services. However if the main problem is her wanting to 'go home', specially in the middle of the night you might need to think about looking at a care home. This site is useful if considering that option
Care Home UK.
I'm sure others will be along with their experiences and ideas soon. You might also want to start your own thread. Not only does that mean more people will see it and reply, I found having your own thread is useful as a sort of diary of what is happening as you try and get your head round the changes happening to your mother.
