What is dementia?
Dementia is a broad term meaning that a person's thinking skills have worsened to the point that they are having difficulty managing their normal day-to-day responsibilities. Dementia can have many causes. The most common cause is the abnormal accumulation of amyloid and tau proteins in the brain (this is called 'Alzheimer's disease'), but dementia can also be caused by the accumulation of other types of abnormal proteins in the brain (such as in 'Lewy body dementia'), a stroke ('vascular dementia') or alcohol abuse ('Korsakoff's dementia'). In order to differentiate between causes of dementia, clinicians use cognitive assessments, blood tests, and brain scans.
