My elderly dad has had dementia for a while and while it's been getting worse, he was still able to walk around, make his cup of tea, follow the news etc. A few days ago he had a fall and bumped his head. CT scan is clear, no acute head injury but he's in the hospital having tests. Since being in the hospital he has completely changed. He can't feed himself, can't hold cup, can't walk without aid, it's likely he's been through a massive decline and it's so upsetting to see. I can't get my head around that last week, he was fine. Has anyone experienced this with a loved one and did they ever recover or just get worse?
