The Alzheimer's Society are calling for more help to ensure no-one in Wales is denied access to information and support, following a diagnosis of dementia.
The charity's 'Right to Know' campaign is also calling for a higher dementia diagnosis rate across Wales, and a guarantee that everyone has access to a Dementia Adviser or equivalent, following a diagnosis.
Many people in Wales face daily challenges whilst living with dementia. It's disgraceful to think nearly two thirds of them have an added fight, to get a diagnosis.
Everyone with dementia has a right to know. To have access to the certainty of a diagnosis and the right support to come to terms with and manage the condition should not depend on your postcode.
– Sue Phelps, Director of Alzheimer's Society in Wales
Welsh actress Ruth Jones has today spoken of her family's battle to understand the onset of her mother-in-law's Alzheimer's disease.
It comes as a campaign is launched to raise more awareness of dementia. It is aimed at businesses like hairdressers, in the hope that they can provide customers with advice on where to go for help, if they think they have it.
With an ageing population, Alzheimer's Society says that the number of dementia sufferers could rise by 40 percent in the next decade.
It is currently Dementia Awareness Week, running between 19 and 25 May this year.
Alzheimer's Society says it simply wants to get people talking about dementia.
It is using the hashtag #TalkDementia on Twitter, as part of the campaign.
The charity has an online forum for people to talk to others about dementia and tips about how to raise awareness.
It has also launched 'Five things you should know about dementia': it is not a natural part of ageing; it's caused by diseases of the brain; it's not just about losing your memory; it's possible to live well with dementia; and there's more to a person than dementia.
There's an estimated 45,000 people in Wales living with dementia and over the next 10 years, that figure is expected to rise to 56,000.
In a bid to raise awareness and get people talking about dementia, Alzheimer's Society is launching a new initiative to get hairdressers in Gwent to raise the issue with their customers and provide them with information.
The charity is holding a range of events to mark Dementia Awareness Week.
