Not everyone with dementia has a formal diagnosis. Since 2012, the NHS has been seeking to ensure that patients suffering from dementia are given a formal diagnosis so that they can receive appropriate care and support. The national target is for two thirds of people with dementia to be formally diagnosed.
The Dementia 65+ estimated diagnosis rate indicator tracks this ambition by comparing the number of people thought to have dementia with the number of people diagnosed with dementia, aged 65 and over.
The indicator is updated every month.
