How to handle someone with Dementia

My Father and Mother in law both died with dementia.
Best you can do is keep them clean, fed and safe which is a challenge in itself.
Oh and try to keep Dad from going out the door naked except for his gun belt and .38 looking for “**ssy” in a snowstorm at 11pm.
Yea, that happened. :D
My Brother and I got a good laugh out of that one.
That reminds me. When my dad was starting to get bad. He would wonder outside in his underwear and start collecting all the trash cans in the neighborhood.
