title: Dementia: What is it All About?
abstract: Dementia is an increasingly frequent clinical syndrome that is characterised by deficits in multiple cognitive domains, changes in behaviour and functional deterioration. Alzheimer's disease, together with vascular dementia, account for 2/3 of all cases of dementia. Other less frequent causes of dementia include dementia with Lewy bodies and frontotemporal dementia. This paper reviews the clinical, pathophysiological and neuroimaging aspects of these four prevalent causes of dementia.
