title: Dementia.
abstract: Dementia describes the syndrome of generalized cognitive impairment in an alert patient. There are many causes, some of which are treatable and so full investigation is necessary. The main causes are Alzheimer's disease and vascular disease and although no specific treatments are yet available important advances have been made in understanding the biochemical abnormalities involved.
