Walking confusion?

As usual, I just love hearing other people’s experiences, I find it so helpful. Anyone have a loved one with dementia who struggles to walk, not because of physical limitations but because they are confused?

My father in law is 68 with early onset unspecified dementia. He’s been progressing pretty slowly over the last few years. He’s almost completely incontinent (urine and bowel, can make it to the toilet sometimes) and we assist with everything. His son showers him, dresses him, takes him to the toilet, holds his hand to lead him places, etc. We make all his meals and chop them small so he doesn’t choke. He pockets food in his cheeks. But it’s all related to cognitive decline - he is physically super healthy. No major comorbidities, he’s very physically fit. He used to walk every day with his son around the block, 10-30 minutes of walking every day. He still goes to daycare 3x a week and dances, walks around, etc. This clearly isn’t a physical decline, he’s just too confused to walk normally. He shuffles in small steps. He freezes and won’t move at all despite cuing. He’s almost fallen multiple times in the last day. It seemed to come on so suddenly.
He recently had a bout of constipation followed by 2 days of constant diarrhea. I know he was exhausted from that. But he’s had a couple days to rest/recover and his GI symptoms have all resolved, and now he’s starting to have issues walking.

Any insight/advice is always appreciated!
