Dementia surveillance illustrates the disparities that exist across England in relation to the diagnosis of people with dementia and subsequent care they receive. It is aimed at informing national and local policy development, and for local commissioners to help in planning services around the needs of people with dementia. This document concentrates on England and 7 NHS regional geographies and shows data from April 2023 to February 2024. It includes comparisons of the latest values for the 42 Integrated Care Boards (ICB). Separate factsheets for the ICB are also available.

People with dementia

The national aspiration is that two-thirds (66.7%) of people estimated to be living with dementia should have a formal diagnosis recorded in their primary care notes. This reflects the 2015 prime minister’s challenge to increase the numbers with a formal diagnosis of dementia. A timely diagnosis enables people living with dementia, their carers and healthcare staff to plan accordingly and work together to improve health and care outcomes. The 2 sections below present data on dementia diagnosis rates and diagnosed prevalence.

Diagnosis rates

NHS England measure compliance with the national aspiration of dementia diagnosis levels using the estimated dementia diagnosis rate (EDDR). The EDDR is calculated as the number of people with a formal diagnosis of dementia divided by the number of people in the locality, aged 65 years and older, who are estimated to have dementia using the Cognitive & Function Assessment Study (CFAS II) prevalence rates.

The interactive chart in figure 1.1 shows the monthly value for EDDR as the rate of people diagnosed with dementia per 100 people expected to have dementia, aged 65 and over. Trend lines are shown for England and NHS regions against the national diagnosis aspiration line of 66.7%.

Figure 1.1

In February 2024, there were 718,336 people aged 65 and over estimated to have dementia in England. Of these, 463,514 have been formally diagnosed and added to the dementia register making the EDDR for England 64.5%. This was statistically similar to the 66.7% aspiration. The rate varied over the reporting time between 63.1% and 64.7%.

When looking at the regional variance for this period, the highest rate of 69.4% was in the North West while South West noted the lowest rate of 59.7%. Compared to the 66.7% aspiration value, none of the NHS regions placed statistically above it, South West placed below it and 6 regions showed no significant difference (Midlands, London, South East, East of England, North West, and North East and Yorkshire).

The interactive chart in figure 1.2 shows the latest value for EDDR as the rate of people diagnosed with dementia per 100 people expected to have dementia, aged 65 and over. The bar chart displays 42 ICB in England grouped by NHS region.

Figure 1.2

In February 2024, the EDDR for England varied across the 42 ICB between 53.9% (Herefordshire and Worcestershire) and 75.5% (South Yorkshire). One ICB was significantly above the 66.7% national aspiration (South Yorkshire) and 15 below it (Norfolk and Waveney, Suffolk and North East Essex, Cambridgeshire and Peterborough, North East London, Shropshire, Telford and Wrekin, Birmingham and Solihull, Coventry and Warwickshire, Herefordshire and Worcestershire, Humber and North Yorkshire, Kent and Medway, Cornwall and the Isles of Scilly, Bath and North East Somerset, Swindon and Wiltshire, Devon, Dorset, and Somerset).

Diagnosed prevalence

Prevalence describes the frequency of existing cases in a defined population at a given point in time. Measuring prevalence can be particularly helpful in assessing the need for preventive action and the planning of health services. Prevalence illustrated below is the number of people with a formal diagnosis of dementia on their primary care record, as a percentage of those registered with the primary care practices. The population it measures is aged 65 years and older.

The interactive chart in figure 2.1 shows the monthly prevalence for those with a formal diagnosis of dementia as trend lines for England and NHS regions.

Figure 2.1

In February 2024, the diagnosed dementia prevalence in people aged 65 and over for England was 4.1% of the 11.2 million registered patients. Over the reporting time, the prevalence was between 4% and 4.2%. Across NHS regions, the highest rate of 4.3% was in the North West while South West noted the lowest rate of 3.9%. Compared to the 4.1% national value, 2 of the regions placed above it (North West and North East and Yorkshire), one placed below it, and 4 regions showed no statistical difference (Midlands, London, South East, and East of England).

The interactive chart in figure 2.2 shows the latest prevalence for those with a formal diagnosis of dementia as a bar chart for the 42 ICB in England grouped by NHS region.

Figure 2.2

In February 2024, the diagnosed dementia prevalence in people aged 65 and over for England varied across the 42 ICB between 3.5% (Herefordshire and Worcestershire) and 4.7% (South Yorkshire and Surrey Heartlands).

Services

Ensuring dementia patients receive a high quality of care is one of the aspirations outlined in the Prime Minister’s challenge on dementia 2020. This section illustrates data on memory clinic referrals and antipsychotic prescribing for people of all ages with a record of dementia diagnosis.

Memory assessment services

The majority of formal diagnoses of dementia are provided by specialist clinicians at memory assessment services (memory clinics). To receive a referral to a memory clinic from primary care, an individual should be first assessed to eliminate any potential underlying causes that may be contributing to memory and welfare issues. Since March 2020, the COVID19 pandemic has affected the provision of the usual health services in England, limiting access to memory assessment services.

The interactive bar chart in figure 3.1 shows the referrals to memory clinics as a percentage of all individuals receiving an assessment for dementia since 1 April 2023 for England and NHS regions. The memory clinic referrals data is cumulative and resets in April each year.

Figure 3.1

Between April 2023 and February 2024, there were 35,956 referrals to specialist memory assessment services in England. This was 13.2% of all dementia assessments provided. Higher than England percentages of referrals were recorded in 2 of the regions (East of England and North East and Yorkshire) with the top value of 18.3% in East of England. Lowest value was in South West (11.3%) with 5 of the regions placed statistically below the England value (Midlands, London, South East, South West, and North West).

The interactive bar chart in figure 3.2 shows the referrals to memory clinics as a percentage of all individuals receiving an assessment for dementia since 1 April 2023 for the 42 ICB in England grouped by NHS region. The memory clinic referrals data is cumulative and resets in April each year.

Figure 3.2

Between April 2023 and February 2024, the percentage of referrals to specialist memory assessment services in England out of all dementia assessments provided in England varied across the 42 ICB between 4.9% (Dorset) and 34.1% (Derby and Derbyshire).

Antipsychotic prescribing

People with dementia may develop behavioural and psychological symptoms (BPSD) including agitation, aggression, distress, and psychosis. They are often prescribed antipsychotic medication. The National Institute for Health and Care Excellence (NICE) guidance recommends prescription of antipsychotics should be undertaken with serious consideration.

The interactive chart in figure 4.1 shows the number of people with dementia receiving a prescription for antipsychotic medication in the preceding 6 week period, as a percentage of all individuals with a formal diagnosis of dementia. It displays the England and NHS regional trend lines.

Figure 4.1

In February 2024, 8.9% of people with a diagnosis of dementia also received a prescription for antipsychotic medication in the preceding 6 week period in England. The highest levels of antipsychotic prescribing were in 2 of the regions (Midlands and East of England) with the top value of 10.1% in East of England. Lowest prescribing levels were in North East and Yorkshire (7.6%) with 3 of the regions placed statistically below the England value (South West, North West, and North East and Yorkshire). The remaining 2 areas (London and South East) showed no statistical difference from the national prescribing levels.

The interactive chart in figure 4.2 shows the number of people with dementia receiving a prescription for antipsychotic medication in the preceding 6 week period, as a percentage of all individuals with a formal diagnosis of dementia. The bar chart displays 42 ICB in England grouped by NHS region.

Figure 4.2

In February 2024, the percentage of people with a diagnosis of dementia who also received a prescription for antipsychotic medication in the preceding 6 week period in England varied across the 42 ICB between 6.7% (Humber and North Yorkshire and Bath and North East Somerset, Swindon and Wiltshire) and 11.9% (Suffolk and North East Essex).

Coverage

This document is using Primary Care Dementia Data, which replaced the Recorded Dementia Diagnosis data in October 2022. The latter has been analysed previously in Wider Impact of Covid19 on Health - Dementia Surveillance Factsheet and reflects geographies from before July 2022. Geography changes are detailed by the data provider.

In the new Primary Care Dementia Data the primary care practice coverage was relatively low to start with, while practices were signing up to the new data collection system. That number has recovered to over 95% in March 2023 but still had incomplete data due to one of the Integrated Care Boards not submitting any data at all. From April 2023 all the ICB submit data and the coverage rises above 98%, which is why that date is the first reported in this factsheet. The latest coverage in February 2024 is 98.7%.

Statistical comparisons

Statistical data comparisons have been made using 95% confidence intervals. If the area’s confidence interval contains the comparator value of the higher geography, the values for both areas are not significantly statistically different from each other. These values are described as ‘not different’ in the factsheet. If the whole confidence interval is above the comparator value, the area’s value is significantly statistically higher than the comparator. These values are described as ‘higher’ or ‘above’. If the whole confidence interval is below the comparator value, the area’s value is significantly statistically lower than the comparator. These values are described as ‘below’ or ‘lower’.
