A recent analysis published in The Lancet Public Health reveals a substantial escalation in dementia cases in England and Wales since 2008, potentially resulting in 1.7 million individuals affected by 2040. This unexpected surge, spanning various demographic groups, underscores the critical need for revising policies and enhancing care strategies for dementia, positioning it as a major health and social care concern.
The study, led by University College London, predicts that the number of dementia cases in England and Wales might surpass 1.7 million by 2040, which is over 40% higher than earlier projections.
Previous research, using data until 2010, suggested a decline in dementia rates in affluent nations. However, the new findings indicate a rise in dementia cases in England and Wales beginning in 2008.
Based on these findings, experts anticipate that future dementia numbers in these regions could be considerably higher than previously expected.
Projected Growth in Dementia Cases
Earlier studies predicted a 57% increase in dementia cases in England and Wales, from 0.77 million in 2016 to 1.2 million in 2040.
The latest research, backed by the UK Economic and Social Research Council, however, suggests a possible rise to 1.7 million cases.
Examination of Longitudinal Data
In this study, data from nine waves (2002-2019) of the English Longitudinal Study of Ageing (ELSA) was analyzed, focusing on individuals over 50 living in private households in England.
The findings showed a 28.8% decrease in dementia incidence from 2002 to 2008, but a subsequent 25.2% increase from 2008 to 2016.
This non-linear trend was consistent across various subgroups, including age, gender, and educational levels.
Significantly, the study highlighted increasing disparities in dementia incidence rates among different educational groups, with those having lower education experiencing a slower decline between 2002-2008 and a steeper increase post-2008.
Consequences of Rising Dementia Rates
If the rate of increase continues as observed between 2008 and 2016 (2.8% annually), the number of dementia cases in England and Wales could reach 1.7 million by 2040, nearly double the 2023 figure. This is in stark contrast to the one million cases expected had the decline continued as previously reported.
Dr. Yuntao Chen of the UCL Institute of Epidemiology & Health Care expressed alarm at the potential 70% higher figure compared to if the decline had persisted.
Factors Beyond Aging Population
While an aging population is often cited for the rise in dementia cases, the study also noted an increase in dementia onset within older age groups.
Professor Eric Brunner, the principal investigator, emphasized that dementia is becoming an increasingly urgent policy issue, with both the aging population and rising onset rates in older age groups contributing to the trend.
Views from Alzheimer’s Society
James White from Alzheimer’s Society highlighted the significance of this study, underscoring dementia as the most critical health and social care issue currently. He stressed the importance of timely and accurate diagnosis and the mounting pressure on social care systems, which are already under strain.

Frequently Asked Questions (FAQs) about Dementia Incidence England Wales
What does the recent study in The Lancet Public Health reveal about dementia cases in England and Wales?
The study indicates a significant increase in dementia cases in England and Wales since 2008, predicting that by 2040, there could be 1.7 million individuals living with dementia, which is over 40% more than previous forecasts.
How does the new research on dementia differ from previous studies?
While earlier studies, based on data up to 2010, suggested a decline in dementia rates in high-income countries, the new research reveals an increase in dementia incidence in England and Wales after 2008.
What are the projections for dementia cases in England and Wales according to the new research?
The new study projects that the number of people living with dementia in England and Wales could rise to 1.7 million by 2040, a substantial increase from previous predictions.
What data was used in the new study on dementia incidence?
The study examined data from the English Longitudinal Study of Ageing, which included nine waves of data from people over 50 living in private households in England, spanning from 2002 to 2019.
What significant trend was observed in the study regarding dementia incidence rates?
The study found that the dementia incidence rate decreased by 28.8% from 2002 to 2008 but increased again by 25.2% between 2008 and 2016, showing a non-linear pattern across different demographic subgroups.
What implications does the increased incidence of dementia have?
The rising trend in dementia cases indicates a need for urgent revision of health and social care policies and strategies to address the growing challenge of dementia care.
How does the study address the factors beyond an aging population for the rise in dementia cases?
The research suggests that not only is the aging population a major factor, but the rate of dementia onset within older age groups is also increasing, indicating a more complex issue than previously understood.

Didnt know education level affects dementia rates, this study really opens your eyes to a lot of things we don’t normally think about.
i read about the decline in dementia before, but this new study is kinda scary, shows how quickly things can change.
wow, 1.7 million cases by 2040? that’s really shocking, we definitely need better policies in place.
interesting to see how the data changes over time, but it’s really worrying for older people, and the healthcare system.
