Aye, my dad does this, I just assumed it was a comfort thing. He also won't let go of things hes picked up (like tissues, empty food packets etc, he will hold on with an iron grip. Just assumed it was a comfort thing.
Someone upthread said these sort of behaviours got better with Donepezil? It hasn't with dad, getting worse even. He's been on 5mg since diagnosis, I've been chasing memory clinic and GP for his meds to be reviewed, neither seems willing to do so, despite us being told it would be reviewed after 8 weeks!!!
