Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, how many people were diagnosed with dementia in (a) 2020 and (b) 2024.

The data requested is not collected centrally.

We can provide a count of patients with a recorded diagnosis of dementia. This is a count of patients with a dementia diagnosis on their general practice record at the specified point in time irrespective of when the diagnosis was made. The data has been published under the Primary Care Dementia Data publication series since April 2022, and under the Recorded Dementia Diagnoses publication series prior to that.

The following table shows the dementia diagnosis figures for all ages for December of each year for 2019, 2020, 2023, and 2024:

It is worth highlighting that these represent an estimate of the total number of people living with a diagnosis of dementia, and that changes over 2020 and over 2024 do not reflect only new diagnoses.
