Dad has some form of dementia. Never formally diagnosed by a neurologist. He and Mom are in a wonderful, trustworthy AL facility.
Dad absolutely cannot walk or even be helpful with transfers during his waking hours. However, the staff will occasionally tell us that Dad "was found in the shower at 3 am", or "the staff found him wandering their room in the middle of the night several times. He was confused..."
He has NO leg or core strength whatsoever.
It was suggested that it is his dementia that keeps him from walking, but that at night he's likely in a twilight sleep or even sleep walking.
Is this really possible? The brain is such a wonderful and horrible thing, all at once.
