PSP can cause the sufferer to lose impulse control, which happened to my Dad. It led to him (when he was in that stage of falling) to try to stand when he'd been told repeatedly to ask for help before standing. It was not his fault. It was the psp, strikes again, rears it's ugly head, often just when you think it can't get much worse. It may help to keep in mind that the loss of impulse control isn't their fault because it was very frustrating. He reminded me of a rebellious child at that time. He passed away 26 days ago after an 11 year battle. I was one of his 3 caretakers the last 2 years. Daddy was a tall healthy man until psp.
Another thing it can do is cause movements and reaction time to be very slow, so that as they fall to the floor, they're unable to break their fall with the use of their hands or body. So Daddy fell like a tree falling and landed with a huge crash, often onto his poor head. Then he'd be on the floor, often bleeding, trembling and QUICKLY weakened, and unable to get up unaided. We have a Hoover Lift thank God because without it, he'd have spent the last yr of his life in a crappy little hospital bed, at home but that would have been even worse.
However before the Hoover lift, when he was falling and so weak on the floor, I all but ruined my lower back. I've always had a strong back but now, if I lift anything too heavy, probably for the rest of my life, it flares up and can last for weeks as I've recently discovered. SO please carers, don't do what I did. Always have a device or another person to help you anytime you move your psp sufferer. Find a Hoover lift, sooner rather than later, and USE it. We had it for a long time before I started using it and that was dumb.
Pic is me, with eyes half closed haha, my beautiful daughter and Daddy, just 4 years ago. Boy did a lot happen in 4 years for my Dad and us all because of psp. I despise it so much. And I miss my Daddy SO SO MUCH.
