INTRODUCTION
Dementia is a progressive illness which occurs when the brain is damaged by disorders and diseases such as Alzheimer 's disease, Huntington 's disease and Creutzfeldt-Jakob disease (CJD) or a series of strokes.
The term dementia is not the actual disease in its own right but is the collective term used to describe the group of related symptoms caused by the gradual death of brain cells. These symptoms include memory loss, problems with reasoning, perception, communication skills and physical ability. (NHS Choices, 2014)
It is estimated that by 2015 there will be approximately 850,000 people living with dementia in the UK. (Alzheimer’s Society, 2014)
