Over the past 5.5 months my mom was in several hospitals and rehab facilities; she came home on Nov 5 and is having a tough time adjusting to being home again. Medically she is great but she has some bouts of confusion and it really frustrates her. How do I help her in the adjustment phase?
Does your Mom live with you? As time goes by, unfortunately her Dementia is going to worsen, and maybe going into Memory Care now, will ease her path into residents care, rather than later, when she is really confuse. My heart goes out to you and your family. It's so hard! Sorry!
Is her husband still taking care of her in her home?
GA has given good advice about not overwhelming her with new people.
You may already know this from caring for her before her hospitalizations, but it is always best if you can avoid arguing with someone who has dementia, even when they are clearly wrong. If she has trouble finding the bathroom and then says, "Well this isn't where it was before!" answer something like, "Each place you've been has had the bathroom in a different place. It really gets confusing, doesn't it? Here the bathroom is in the green hallway, right across from the lighthouse picture." Help orient her, but try not to make her feel bad for being wrong.
Your profile states that she's living in a hospital, but your post states otherwise. Is she living alone? Are you and/or other family members close by? If so, are you able to spend time with her on a regular basis to help her when she gets confused, and about what issues generally does she get confused?
Your profile states that she has dementia, and having been out of her home for 5.5 months would be a major adjustment for anyone.
If you or other family members are able, I'd spend as much time as possible with her, going through the ADLswith her in case she needs that assistance, and staying with her when she becomes confused to provide, if nothing more, moral support for her.
Going from places where needs are addressed for someone and control is literally taken out of their hands can be a really disorienting experience for anyone. Can you think of ways to reorient her to her former lifestyle, doing things together?
