Fewer than half of the people suffering from dementia, who currently live in care homes, enjoy a good quality of life, a charity has warned.
The report from the Alzheimer's Society also found that record numbers of people in care homes have the condition.
It said 80 per cent of people in residential care homes have either memory loss or dementia.
Previous estimates put the number of people with the condition at just over 60 per cent.
The Alzheimer's Society is encouraging people to learn about dementia in order to make those suffering from the disease feel included and understood.
Alzheimer's Society research shows that 41% of people in the North East feel they have a role to play to support people with dementia, but only 48% feel they have a good understanding of the disease.
'Dementia Friends' is an initiative to help a million people understand how to speak sensitively to a person suffering from dementia. The project helps people to make those with dementia feel included and understood.
The Alzheimer's Society is trying to recruit a million 'Dementia Friends'. They want people to go and visit those suffering from the disease. Volunteers can register on the Alzheimer's Society website.
