This information is not collected centrally by the Health and Social Care Information Centre. The Quality and Outcomes Framework contains information on registered patients with dementia, but does not contain age breakdowns. The National Dementia and Antipsychotic Prescribing Audit contains information that is relevant. However it is not mandatory and so does not have 100% coverage. The audit has data from 45.7% of the general practitioner practices in England and is therefore not suitable for providing a national figure or regional breakdowns.
