I suffer from AD and FTD. What really kills us? Well if we should happen to live healthy, no uncurrable diseases and have good care, we die when our BRAIN finally has forgotten what it is supposed to do. Forgets to tell the organs what to do, like Hey Lungs, Breathe, you heart pump, Mr. Liver you have to filter and oh mr. & mrs kidney clean up the waste. In simple raw terms, we kill ourselves, because our brain forgets to tell us how to stay alive. That is what Dementia Does, It's Job. Then we are set free from the ravages of the disease.
I love the term "EXPERT", the community here told me it was a subjective term. Well Charlie Chan in a movie expressed it as it really is, "AN EXPERT IS A PERSON WHO MAKES SNAP Desission AND IS SOMETIMES RIGHT". As you can see I see things in a much different light living the disease.
