Page "Dementia" Paragraph 6

Some of the most common forms of dementia are: Alzheimer's disease, vascular dementia, frontotemporal dementia, semantic dementia and dementia with Lewy bodies.

It is possible for a patient to exhibit two or more dementing processes at the same time, as none of the known types of dementia protects against the others.

Indeed, about ten per cent of people with dementia have what is known as " mixed dementia ", which may be a combination of Alzheimer's disease and multi-infarct dementia.
