Now, the intersection of guns and dementia.

Around half of all Americans older than 65 live in a home with a firearm. And one in three senior citizens dies with some form of dementia. By one estimate, by 2050, as many as 12 million people with dementia may live in homes with guns.

That is prompting doctors, researchers and family members to ask how to prevent a potential tragedy.
