Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what the dementia diagnosis rate was for people aged under 65 who had developed symptoms on 13 January 2025; and if he will publish a monthly estimate of this rate within national primary care dementia data.

The dementia diagnosis rate is not calculated for patients aged under 65 years old. This is because the numbers of patients known to have dementia in the sample population age groups comprising the zero- to 64-year-old age range is not large enough for reliable estimates to be made.

The Primary Care Dementia Data publication includes a monthly count of the number of patients aged 65 years old and under who do have a dementia diagnosis on their patient record, which is expressed as a raw count, and as a percentage of registered patients aged zero to 64 years old.
