Dr. Emmy Betz, who studies guns and dementia at the University of Colorado School of Medicine in Denver, suggests that families draw up a firearms agreement — a kind of advance directive for guns.
The conversation, Betz says, might include questions like "Who do you want to be the one to say, 'I think it's time'? Who do you want to give [your guns] to? Is it your family member? Is it Joe down at the gun club? So that you're still the one making the decision. Even if when the time comes, you're not aware of what's happening."
