My 79 yr old dad has had lots of falls recently. He went to rehab and improved. On his last day there he fell. He had to wait on the floor for over 2 hours for paramedics. In that time he wet himself. A consequence of the fall was internal bleeding (blood thinners) it seemed to settle. He's been in hospital for 3 days now and is getting worse each day. He's been moved a lot and now they think he has dementia. He was a completely different person 3 days ago. Can dementia show so bad suddenly? He now can't walk or stand, feed himself, coordinate his drink. He's in bed with padded cot sides in a state of confusion and discomfort. Doesn't know where he is etc. Apparently he became violent last night. He isn't himself at all. He's very deaf which hasn't helped. He's been due a brain scan for the last 2 days. He was due a chest CT this week because an X-ray a month ago showed a shadow. I've been told they did it yesterday. I was told by a nurse that the dr wants to speak to me tomorrow (today Monday) about the chest CT. I know they have suspicion that it is pulmonary metastasis because a nurse accidentally read that out to me on the phone. I'm preparing for the worst. I'm shocked by his sudden change. I just hope it doesn't go on to long, I don't want him to suffer.
