Eli5 how exactly does dementia cause people to die faster?

764 views

I completely understand how dementia is horrific in that it eliminates a persons mental faculties causing them to forget anyone and everything they knew, but what/why does it eventually cause death? Is it because their body “forgets” how to function or what?

Side note: maybe I’m wrong in assuming that everyone will die once diagnosed? Is their a spectrum for this?

my great grandma had dementia and died bc of it. it causes the person to forget things yeah but later on as it worsens they’ll forget how to pee, eat, normal bodily functions and then their vital organs like their heart lungs would fail too. how i think of it is like when ur breathing u dont need to think about doing it like walking cuZ u just do. when the lungs “forget” how to function then thats no good. idk probably best to search it up but thats what my parents told me about it
