Dementia is a syndrome in which there is impairment in several brain functions such as memory, learning, judgement and orientation, and where these are often accompanied by deterioration in motivation, emotional control and social behaviour. Dementia is usually of a chronic or progressive nature. Examples of diseases associated with dementia are Alzheimer disease, vascular disease, Pick disease and Parkinson’s disease.
