Question: Can dementia cause death?

Debbie Kinsey answered on 21 Nov 2019:

Because we don’t have a cure for dementia, everyone who has it will die with it, but it might not be the dementia that causes their death, if that makes sense. A lot of people with later-stage dementia die of things like pneumonia (which is a lung infection). Dementia can shorten your life because the brain controls so many systems in your body, so you might become more frail or get ill more easily, and then something else like pneumonia causes your death.
