The National Audit Office report “Improving services and support for people with dementia” estimated that approximately two thirds of people with dementia do not receive a formal diagnosis or have contact with specialist services at any time in their illness.
The Department does not have data on the number of people diagnosed with Alzheimer’s and dementia in each year from 2000 to 2008. However, for 2006-07 and 2007-08 the General Practitioner Quality and Outcomes Framework (QOF) has recorded the number of people with a diagnosis of dementia but this does not distinguish between Alzheimer’s disease and other forms of dementia.
The publication “Revisions to the GMS Contract 2006-07”, produced by NHS Employers, states that Alzheimer’s disease accounts for 50-75 per cent. of cases of dementia so the count of patients with dementia gives an indication of the number with Alzheimer’s disease.
In 2006-07, there were 212,794 and in 2007-08, there were 220,246 people with a diagnosis of dementia, as recorded on practice disease registers in England.
