Dementia causes. Dementias can be caused by brain cell death, and neurodegenerative disease - progressive brain cell death that happens over time - is associated with most dementias. However it is not known if the dementia causes the brain cell death, or the brain cell death causes the dementia. But, as well as progressive brain cell death, like that seen in Alzheimer's disease, dementia can be caused by a head injury, a stroke, or a brain tumor, among other causes.
