Growing Dementia Challenge to Retain Its Surge On!

According to previous research* in England and Wales, the number of people living with dementia was previously predicted to increase by 57% from 0.77 million in 2016 to 1.2 million in 2040.

However, the new research, funded by the UK Economic and Social Research Council, suggests that this figure could be as high as 1.7 million.

Dementia’s Gathering Storm

Researchers examined nine waves of data from people over the age of 50 and living in private households in England between 2002 and 2019, from the English Longitudinal Study of Ageing (ELSA).

They found that the dementia incidence rate (a measure that considers what percentage of the population in each age group has dementia) decreased by 28.8% between 2002 and 2008. However, it increased again by 25.2% between 2008 and 2016.

A similar non-linear pattern was observed across subgroups according to age, sex, and educational attainment.

Most notably, researchers found that disparities in the rate of dementia incidence were increasing between education groups, as there was both a slower decline in 2002-2008 and a faster increase after 2008 in participants with lower educational attainment.

If the incidence rate increases as fast as what was observed between 2008 and 2016 (a 2.8% increase per year) researchers predict that the number of people with dementia in England and Wales is set to increase to 1.7 million by 2040 – approximately twice the number in 2023. This compares to an estimate of one million people if dementia rates had continued to decline as previously reported.

Urgent Action Required

Lead author, Dr Yuntao Chen (UCL Institute of Epidemiology & Health Care), said: “It is shocking to think that the number of people living with dementia by 2040 may be up to 70% higher than if dementia incidence had continued to decline.”

“Not only will this have a devastating effect on the lives of those involved but it will also put a considerably larger burden on health and social care than current forecasts predict.”

“Continued monitoring of the incidence trend will be crucial in shaping social care policy.”

Although an increase in dementia cases has often been attributed to an aging population, the researchers also found that the rate of dementia onset within older age groups is also increasing.

Principal investigator, Professor Eric Brunner (UCL Institute of Epidemiology & Health Care), said: “Our research has exposed that dementia is likely to be a more urgent policy problem than previously recognised – even if the current trend continues for just a few years.”

“We have found that not only is the aging population a major driver of the trend in England and Wales but also the number of people developing dementia within older age groups is increasing.”

“We don’t know how long this pattern will continue but the UK needs to be prepared so we can ensure that everyone affected, whatever their financial circumstances, can access the help and support that they need.”

James White, Alzheimer’s Society’s Head of National Influencing, commented: “Dementia is the biggest health and social care issue of our time. Statistics from this Lancet Public Health study are a stark reminder that, without action, the individual and economic devastation caused by dementia shows no sign of stopping.”

“We know that one in three people born in the UK today will develop this terminal condition in their lifetime. With prevalence on the rise, improving diagnosis has never been more important. Everyone living with dementia must have access to a timely, accurate, and specific diagnosis, and who you are or where you live should have no bearing on this. The figures also make it clear that pressure on our already struggling social care system is only going to increase. Quality social care can make a huge difference in people’s lives, but we know that people with dementia – who are the biggest users of social care – are struggling with a care system that’s costly, difficult to access, and too often not tailored to their needs.”
