Official statistics
Change to dementia type breakdowns
The dementia type breakdowns for months prior to April 2025 provided in the 'Dementia type by Sub ICB Location .csv' will not sum to equal the national total dementia registers. This is because the 'Other' group was split into 'Other - specified dementia types' and 'Other - unspecified dementia types' from April 2025 onwards, and this breakdown is unavailable prior to this.
Users may wish to make use of the 'Dementia type by Sub ICB Location .csv' from the March 2024 release, which includes values against the previous 'Other' dementia type group.

Summary
NHS England collect and publish data about people with dementia at each GP practice in England, to enable NHS GPs and commissioners to make informed choices about how to plan their dementia services around patients’ needs.
The publication includes the rate of dementia diagnosis. As not everyone with dementia has a formal diagnosis, this statistic compares the number of people thought to have dementia with the number of people diagnosed with dementia, aged 65 and over. Where current monthly data for a GP practice is unavailable, the most recent data available are used (up to a maximum of 6 months).
Prior to October 2022, dementia data were collected via the dementia data core contract service and published as the "Recorded Dementia Diagnoses" series. The data in these two publication series are not comparable. This is due to the retrospective application of codes to patient records and changes in patient registration, as well as differences in coverage and the specification of several counts.
