Care from home can offer a compromise for older people who need care but don't want to move into a care home.

But some elderly people suffering from dementia still have to pay for their care, something the Alzheimer's Society wants to see changed.

The NHS covers the cost of healthcare but Alzheimer's disease sufferers and their families are usually saddled with the cost of personal care.

"Dementia is a devastating illness for people suffering it, and our members and now this poll is strongly challenging why is it that this disease, these diseases and the care of them, is somehow treated differently to other very serious illnesses and conditions," Alzheimer's Society chief executive Neil Hunt told the Today programme.

"What we're saying is in these cases there seems to be a presumption still that dementia is just an ordinary aspect of getting old, which it clearly isn't," he added.
