A recent revelation has caused one organisation to speak out about the worrying statistics put forward.
Harriet Millward, the deputy chief executive of the Alzheimer's Research Trust, made her comments in response to a review by Professor Sube Banerjee of Kings College London which found that up to two thirds of the estimated 180,000 people with dementia are receiving anti-psychotic drugs unnecessarily.
Ms Millward said that her organisation hoped these figures would have been published much earlier, adding that she was disappointed with delays lasting for over a year - a period which could have seen as many as 1,800 people dying from the disease.
She continued: "The real issue with these drugs is that, while they benefit some people who have very serious aggression or agitation, it may still be right for some of those people to carry on with the drugs."
The financial cost of dementia to the UK is over £17 billion a year, according to the Alzheimer's Society.
